Duration Product Used:6 months
Purchased At:250
Strengths:Downloadable data to PC, Lots of functions
Weaknesses:Price... must read the manual and follow the directions contain in it for it to be "fit-for-purpose".
Similar Products Used:VDO
Bike Setup:SC Blur XTR Disc
Bottom Line:I have had no problems with this monitor. After reading the manual, I took it out of the box, put it on the bike, strapped on the transmitter, and started riding. If this product is installed properly and programmed the way the instruction manual says, it will work as advertised. After the ride, I uploaded all of the exercises recorded that day into the Polar Precision Performance software on my computer through a USB infrared receiver without any problems.

If you are serious about training or racing you must have a heart rate monitor and software to track and assess your performance. The 720i did exactly what the manufacturer said it would do, and what I expected it to do. There are other comparable products on the market but they all do about the same thing.

Purchased At:LBS
Strengths:Altitude sensor, lots of data storage
Weaknesses:unreliable speed/cadence sensing. Have to dismantle sensors to change battery!
Similar Products Used:VDO bike computer
Bike Setup:Standard Trek 5200 / Scott MTB
Bottom Line:Like one of the other reviewers, I bought this in relative ignorance, believing it must be a quality product if it's made by a big name in the HRM world such as Polar. I just wish I'd read and believed the reviews on this forum before I did. BIG AND EXPENSIVE MISTAKE!

The first unit I had lasted all of 6 hrs(!) before the altitude sensor went bonkers. 0ft one minute, 20000ft the next.

The second (current) unit seems ok, but like many other reviewers, I find the speed sensor is just too unreliable, making the whole (expensive) setup no more than a useless geeky looking watch.

The speed sensor unreliability seems to be getting worse too. On my daily 5 mile trip to work I rarely manage to record the entire 5 miles, usually 4, and often as little as 1 mile! This suggests to me that it cannot be being caused by power lines, etc otherwise the data loss would be much more consistent and anyway, if the device can't cope with a typical suburban environment, it's no use to anybody.

It's no good Polar stating in their manual that reliability is affected by just about everthing that you might come across on a typical ride. If this is the case, then the product is definitely NOT (in english consumer law terms)fit-for-purpose.

However, I don't think the problem is exclusively caused by interference (although undoubtedly some of it is). Like one of the other reviewers, the unit often stops and starts itself when changing speed, but not stopping. - I often get this at traffic lights, when I slow down to say 5 or 6mph behind traffic, the unit gets all confused not knowing if I'm stopped or going, beeping all the way and then it seems to give up, and if it thinks I'm stopped when it does, it takes about 300yds before it wakes up and starts again. - Obviously a crap auto-start algorithm - I never had this problem with the VDO.

Originally, I thought the heavy metalwork of the MTB suspension fork was affecting the signal, but the road bike is all carbon, so that can't be it. I have also tried the two different magnets and just about every different orientation of sensor and magnet that's practically possible, all to no avail. And anyway, if the positioning is that critical, it's a crap design.

I've used it with 2 different heart sensors (I lost the first one), and the same speed sensor problem occurs on both the MTB going to/from work in a suburban environment AND the road bike in a rural environment at weekends (two different speed sensors, both with new replacement batteries).

On the subject of replacement batteries, the design of the speed sensors is incredibly poor. On other products, you use a coin to unscrew the cover, pop out the old battery, plop in a new one put the cover back and you're done. On the Polar ones, you have to take the sensor off the bike, then get hold of a jewellers screwdriver set, dismantle the unit, fiddle around with the cheap and nasty coin-battery clip and then re-assemble the whole thing. To make matters worse, the screws are very cheap soft metal self-tappers screwed into hard plastic, so after a couple of battery changes, the heads shear off. I'm an electronics engineer and have a range of very high quality suitably sized screwdrivers,and the whole operation was an incredibly frustrating experience requiring drilling out the old screws and then replacing them with a bigger set. The whole operation took nearly TWO HOURS TO REPLACE THE BATTERY!

While I'm talking about electronics experience, this product (the radio part anyway) smacks of being designed by an amateur using rules-of-thumb and not understanding the theory required to design a reliable radio device, and thus unable to fix the design when it doesn't perform as expected. I've seen this kind of approach time and time again with exactly these results.

In summary then...

I WOULD NEVER BUY ANOTHER POLAR PRODUCT EVER - AND I WOULD HIGHLY RECOMMEND YOU DON'T WASTE YOUR MONEY AS I DID.

Date Reviewed: August 1, 2005
Favorite Trail:rural paved roads
Duration Product Used:6 months
Price Paid: $280.00
Purchased At:heart rate monitors usa
Strengths:great data logging
Weaknesses:steep learning curve, poor design of speed/cadence senders, peculiar restirictions on display.
Bike Setup:Motobecane 2004 team issue; Bacchetta Corsa.
Bottom Line:I wanted to clear up some of the problems people have been reporting with the speed/cadence functions of the 720i. The units are fairly sensitive to alignment. First of all, for those who see their speed doubled, this is because the magnet is too close to the pickup. The sender is reading two pulses each time the magnet passes by; one as the magnet approaches the sensor, and another as the magnet leaves. To fix this you might try moving the magnet above or below the sensor snout. Intriguingly, when I first got the speed sensor working on my Bacchetta, it was reading 2x the correct speed until I got to 23 mph, then it would show the speed at 1x until I slowed down again.
If your speed reading tends to drop out, you probably have the sender pointing too far forward. This is a matter of getting the antenna in the sender aligned with the antenna in the readout unit. As shown in the instructions, the long axis of the transmitter needs to be parallel to the axis of the cylinder around which the wrist unit is wrapped.
Unfortunately, with the forks on my bikes, this was nearly impossible to do without making special adapters. On my Motobecane, with a semi-bladed Kinesis fork, I was able to saw off a piece of a wooden dowel that I could place against the flat portion of the fork blade while the speed sensor sat against the curve of the dowel and the whole thing was strapped onto the fork with the standard wire ties. I have had no problems with irregular data since making this modification.
My Bacchetta was much more problematic. There was no way to get the speed sensor attached so that it would point inward enough to communicate with the receiver unit. I ended up carving a wooden mounting bracket that straps to the fork and has a peg pointing forward that the transmitter straps to with the Polar logo pointing down. With this setup, the unit is very reliable. But most people wouldn't be able to make this unit on their own.
Polar really needs to fix this problem so that an average cyclist can get the units working on his bike right out of the box.
One positive story about the monitor is that I bought it in winter and made a special bracket to put the speed sensor on the back wheel of my Motobecane while it was mounted in a resistance trainer. Even though the transmitter was over a meter from the receiver, I got reliable data and was able to make a systematic study of my pedaling efficiency at different cadences by maintaining constant wheel speed in different gears (and thus constant power) and comparing my heart rates for different pedaling cadences.

Date Reviewed: July 27, 2005
Duration Product Used:More than 3 years
Price Paid: $300.00
Strengths:Records all the essentials at 5s intervals, and data can be downloaded and analyzed on your PC.
Weaknesses:Heart rate is very sensitive to power line interference. File is closed after 5 minutes of in-activity (this has been extended to 30m in newer models). Speed sensing is flaky even though the sensor is as close as physically possible (on my front fork).
Similar Products Used:Many inexpensive, non-recording computers and HRMs.
Bike Setup:Specialized Epic Disc 2003, upgraded with Dave's Dream wheels, Race Face Deus Cranks, SDG I-Fly seat and post, Race Face stem.
Bottom Line:I was excited about this initially, but its just too unreliable. Under power lines your HR shoots up to 225 and the speed goes crazy. You then have to edit the data afterwards to filter the results.

The speed sensor if flaky (I've replaced the batteries not too long ago, so that's not it) - I rarely make it through a ride with valid speed readings.

I've worked on the Linux decoding SW for this and they do some stupid things. Rather than recording the number of recolutions of the tire (which is the raw input), they record the speed and then derive the distance from this. This gives inaccurate distance measurements, even if you carefully calibrate the unit.

The 5 minute timeout is a pain. I was in a meeting a couple of years ago with a Polar rep. where we mentioned this problem - I hear this has been extended to 30 minutes in the newer units. Doesn't do me any good though.

The temperature readings seem to be quite a bit off as well.

There are lots of bells and whistles, but they just don't do the basics well. In designing something like this, you should focus on the basics: measuring speed, distance, HR, and altitude reliably, and then add features.

I really like the idea of recording all the keys stats about a ride, but I wish this thing was more reliable. It annoys me most of the time.

Unfortunately, there aren't too many alternatives ... and I hate to spend another $300.

Bottom Line:The manual may be a bit long (over 100 pages) but you don't need to read all of it and it does explain the monitor's functions - and there are a LOT of functions.

Of course it's going to pick up interference just like any wireless product. You have to be aware of this fact and it's not a defect. As mentioned by someone earlier, you can change the power setting in the speed sensor but be warned that a higher setting means shorter battery life.

Very good product overall.

Strengths:This is a correction from my earlier review. The product is good for the gym and for the bike. The data is great.
Weaknesses:Small read out for a bike ride. You really don't want to be looking for data when your riding 25mph
Similar Products Used:suunto
Bike Setup:Litespeed Siena
Bottom Line:I wrote a horrific review when I first got the unit. See above. As it turned out I was riding under high voltage wires for most of the 30 mile path. The ride is situated along an electric train path. Thus, the read out went wild on me. I thought it was the unit and it turned out it was the electric interf. from the overhead wires. Odd but true. I now know not to use the unit on that ride. Otherwise, I love the unit. I have been confined to a gym for the Winter and I still love to wear the watch. Another great feature is many cardio machines at the gym pick up the pulse from the chest belt and read out on the machine your on and the watch. I'm looking forward to spring and summer when I get back on my litespeed. I feel bad about the earlier review but I had no idea the overhead eletrical wires would make the unit go nutty.

Strengths:Lots of bells and whistles. Documentation is better than most but still hard. Software is good. Yet, the graphics and navagating is "old school." With all of the great graphics and programs out there function and form should have been better.
Weaknesses:While the manual is better than most you better have some serious time to read it. Close to 100 pages. The watch has too many features. That is coming from a tech nut. Unlike other like products the read out is small and you are glancing to get info. They have crammed so much info on the display that it is hard to read while biking 20MPH. At any given point the display will be providing you with 4 readings. The wireless reception is for hell. It quits out on me at least once per three minutes. When I used the mount for the bike it was near impossible to keep a signal. I had to wear it on my wrist. How dumb is that? There were also readings which were impossible. Unless of course my heart rate jumped to 225 and I was doing 56MPH on my road bike. If this unit isn't defective then they should give up.
Similar Products Used:Suunto Advisor
Bike Setup:Tricked out road bike w/ultegra. Klein Mtn. Bought two set-ups for one watch.
Bottom Line:During my third ride trying to use the watch I had this overwhelming desire to smash the little bugger with a large rock. The watch beeps every time the signal is lost from the wheel sensor. Thus, you get reminded continuously during your ride that the watch is unable to keep data from the wireless sensor on your wheel. We are talking every 30 to 45 seconds. I doubt I ever got more than 5 minutes during the two hour ride with a constant signal. Then when you look at the watch and it tells you your going 56 MPH and your heart is doing 225 bpm you know you have wasted close to $300. I had a Suunto Advizor and bought this b/c of the biking components. My favorite flaw was that no signal can be received when the unit is mounted on the handle bars. It works on the wrist but not on the provided mount. There must be some alloy or something on my bars which interferes with the signal. Since my setup is not exotic who knows why? I have read the 100 page manual three times in the hopes of getting better acquainted with the unit. I know it well and it still works for crap.

I am running it with the IR USB on Windows 98 w/o any problems. The data gets through after two or three tries. The software’s looks is ten years old. With all of the great program designs and graphics you feel they should have gone the extra mile. One nice thing was I was able to get a person, rather quickly, at the company to help me with the driver for the USB. Not the most technical guy but we worked it out.

In the end if this product isn’t defective the company should be flogged for selling the unit. I love their by-line....”Train Like the Pro’s.” I don’t think so.

It pains me to leave this review b/c I wanted to love the product and spent close to 300 bucks on the unit, an extra sensor for my mountain bike and the USB IR. My Suunto Advizor didn’t have the bike interface or the software. Yet, at least I got data. I would seriously look to Ciclosport units. They are well priced and can’t be any worse than this.

About altitude measurements: You must set the altitude regularly (before every ride is probably best). You must set the altitude when the watch has cooled to air temperature. Accuracy is best above 1500 ft elevations.

About the uplink kit. I got the USB version ... much less hassle, but you MUST DOWNLOAD THE LATEST PATCH in order for it to work properly. I run it on WinXP and Win2K. On my Win2K laptop, I had to disable the built-in IR port before it would work properly. Takes a little tilting and fiddling to get the device and PC talking, but once you figure it out the IP uplink is pretty flawless.

Strengths:Loads of features. Ability to download multiple workouts.
Weaknesses:DO NOT purchase the infrared USB connection if you are using Windows XP. That's what I ordered and after hours of attempts and downloading drivers, it simply does not work. Also, when I unplug the device from the USB port, my computer shuts down. I've ordered the infrared device with the serial connection and hope I have better luck. If not, I'll return everything for a refund. I've been using the S510 with soniclink and so far it's worked perfectly. I wanted the S710 because of added features and the ability to store multiple workouts. Another drawback of both the 710 and the 510 is the alarm. It is so weak, I doubt if anyone can hear it. So it's useless to set any of the timers because you'll be unable to hear the alarm when it sounds, anyway.
Similar Products Used:Polar S-510 w/soniclink.
Bike Setup:Trek mountain bike, full suspension
Bottom Line:Again, don't order USB connection if you have Windows XP. I'll write another post when I try the serial connection. If you only need to download one workout at a time, stick with the S-510 with soniclink. If you need a heart rate monitor that has a lot of features and want to keep track of multiple workouts for manual entry, this is the monitor for you.

Bottom Line:The 710 model seems to struggle with computer connectivity and uglyness. The best way to avoid this is to get the new 720i, I got it a couple of months ago and I still have no problems with it. The option to use the IR-da(infraread port) on your computer removes the need for a USB-interface and works like a charm. It`s got a stainess steel finish rather than ugly purple. Still a bit big but no worries unless you`re extremely self conscious. Other than that it`s the excact same product as the 710, and a really amazing tool if you`re serious about training and want to use your computer to record your progress.

Weaknesses:'Power unit' is more expensive (~$325US) than the whole HRM with cadence and USB IR interface (~$300US)...this makes the 'power' add-on very unappealing.

Bottom Line:I'm a Triathlete, I found this site attempting to solve the XP driver issue,... something clicked when reading one of the reviews and I tried the Serial Interface I had in a box, it worked,.. I figured I would share this with you.

I have found that the download works best if I keep the monitor on my wrist and put the IR interface on something about 1" thick (off the table) then launch the download in the software then the monitor. Angle seems to be vital.

Good Monitor, to much monitor for most. I'm starting to like the software better than the Advisor Software (which I thought was good),.. it does take some getting use to b/c there are many options.

Strengths:Works as expected. Reasonable documentation, easy to install speed sensor. IR sync works very well once the upgrade is installed, software is quite easy to use and effective.
Weaknesses:Big and clunky, unattractive (I think). Watch functions take some getting used to, not always intuitive. For example to reset the trip distance is a hassle. Software doesn't work 100% out of the box (Windows XP) and free upgrade needs to be downloaded.

Bottom Line:Definitely the market leader. The functions are outstanding and, if used with the software, provide an easy to use, effective training diary. The watch is a bit too big to use as an everyday wrist watch but I guess they needed the space to fit all the functions. I suggest spending a lot of time familiarising yourself with the software because that the products real strength. The IR transfer to the software is the real killer app, without it the watch is a waste of money and you should go for a cheaper option. In conjunction with the software the product provides information on a scale which was unimaginable even a few years ago. Lost one value chili due to expensive price and the fact that the extras (IR adapter, power and cadence sensors etc) are expensive and should be included in a value package. Overall rating lost one chili due to poor aesthetics and very average ergonomics for such an advanced product.

Strengths:Well developed by company who has done heartrate monitors for a long time. Fairly bullet proof product which gives more information that I could use, but it is nice to have the options if I want it.
Weaknesses:The only thing I don't like is you can't change the chest transmitter battery yourself, which means sending it back to Polar for replacement.

Bike Setup:Mountain - 2002 Giant NRS AIR w/Time Carbon Pedals.

Bottom Line:This definitely the answer to a technogeek's prayer. The unit will act as your bike computer and give you heartrate to boot. If you decide to buy one of these, you are nuts not to buy the IR interface. Yes, you can program it using a computer's speaker, but it doesn't work nearly as well as the interface. With it, you can program intervals, heartrate limits, and form multiple files of different sets of exercises, and program the monitor in a matter of seconds. It takes just a bit to learn all the features, but once you have them down, this thing will give you all the information you could possibily imagine. A superb training tool. I did notice that it can have problems with indoor equipment that has an LED display panel as a part of the equipment, however I can't ding them for that, as they are upfront about stating it in the manual. I wish polar would come out with a chest transmitter so we could change our own battery, still, it's a great piece of training equipment.

-Replaced check strap, problem occurs less frequently.

-My Observations:
-Stops recording when bar mounted on MTB, hill climbing a firetrail.
-No problems recording same trail on my wrist???
-No problems when running.

It's a bit on the big side, I hope this is for durability.

The Altitude sensor is a great way of 'seeing' your fave trail. It's also great to look at the day's climbing total.

All that recording (it does normally work BTW) is great. Riding a racing track and seeing where your cadence, speed or HR can be better is great to improving lap times.

HR training has taken me from a '5km and pass out(literally)' guy 6 months ago to now when I am much faster and can hold 80% for hours(6,8,+?). The other day I did a spin class and managed to pull >90% MHR(lab tested) for over 30 mins(45 min class). I've also lost around 15kg of fat(at least). Now I'm considering and Iron Man and a solo 24hr.

HR training is GREAT and this is a great tool to get you to your goals. If you don't believe me, then rewatch the Le Tour tapes and look at the arms of the top sprinters, I'm sure I saw one of these on all of them...

The software is quite easy to use and has only a few failings. You should be able to clear the watch memory without having to download it first. There should be a 'save all' function if your too tired to add details.

Don't bother putting a cadence sensor on unless you ride only firetail. I tore off the magnet 4 times before the sensor got moved to the road bike. Glue on magnets don't like sticks\branchs etc.

Despite some quibbles with my wife's unit and my speed sensor quibbles I think this is a solid product and if I was to buy a new HRM I'd buy this model again.

Expensive, but well worth it.

Bottom Line:When I got this thing home, the packaging stunk so badly that my wife made me take it out in the garage. After three days in the garage, she made me take it outside on the back patio. The smell was starting to make me sick also. I had difficulty setting up the cadence because on anything but a road course the transmitter is so large that bumps move it around and the signal goes away. The thing is impossible to use on the trainer because there is no position where everything can be placed to get the speed, cadence and heart rate to register on the receiver. The reset button quit working on the first one that I had. I let the LBS manager order another with the hopes that the packaging would not smell so awful. It did, so back outside to the porch. The second one lasted about 30 days before the display quit recording sporadically. It would record for anywhere from 5 to 80 minutes, then stop recording any data (all zeros) and sometimes start up again after 5 to 20 minutes, or sometimes NEVER start again. I took it back and swore I would never buy another Polar product again. Purchase one of these flamers at your own risk.

Strengths:Reliable and interfaces with their PC software, which is FANTASTIC.
Weaknesses:The max distance of the wheel pickup to the watch is 18". Therefore, you probably won't be able to wear the watch, but MUST mount it onto you handle bars.

The software is VERY EASY to use, however, there isn't a manual and the online help is limtited. I keep stumbling into great features, but had I been able to read a manual, I would have KNOWN of the feature sooner.
Similar Products Used:Specialized P-Brain- I returned this. The software is not good and I couldn't get the technical specs from Specialized to write my own. Specialized OEMs the P-Brain.
Bike Setup:1999 Specialized FSR-XC
Bottom Line:This heart rate monitor is the best I've ever seen. The software that runs on your PC is also a fine piece of work. I blindly purchased the S-710 because of the features of the heart rate monitor, but the software ties EVERYTHING together. This product is GREAT! Basically, you download the data to your PC and your workout gets automatically stored in YOUR calendar (my wife is another user and her data gets stored into HER calendar). The software will graphically display your heart rate, speed, altitude, distance and time. You can get stats on the entire workout OR you can select only the time frame you're interested in (i.e. the excercise time of an interval; disregarding the resting time)

Anyone interested in seriously tracking their workout should get this!

My only comment to Polar is they need to better market the software. It is BARELY mentioned on their website, but is SUCH a valuable piece to this heart rate monitor.

Strengths:Great all-in-one unit. Software quite good with lots of heart rate analysis tools.
5 second datalogging of speed, cadence, HR and altitude for over 8 hours gives a good picture of how a ride went.
Weaknesses:Looks too odd as a wrist watch.
Speed and Cadence sensor shape only suits certain rare fitment conditions. I ended up having to strap the speed sensor on with tape!
The cadence sensor range was only 530mm on the bike i.e. useless, (it did 1070mm on the table) this was mentioned in a previous review. Polar UK have said they can do a hardware mod which will double the range. The Speed sensor was ok at 480mm on the bike and did 730mm on the table). Interference sometimes puts spikes in the data.
Come back wires, all is forgiven!
The PC sonic link nearly but never quite worked, so I had to buy the IR link for £28. This works fine but its another plastic gadget to clutter up the desk :-(

3. Really easy download to computer.
4. Really easy plotting and review of exercise over the days-weeks-months.
5. THE tool for a serious performance enhancement program.
Weaknesses:Very short range of cadence and speed transmitters meant I had to mount the "wristwatch" on the top-tube of my Jekyll 2000 to get it to work. Must buy $40 computer interface to use it with the computer.
Similar Products Used:Several Polar brand heart monitors over the years.
Bike Setup:MTB with Polar S710 mounted on top-tube of Jekyll 2000. Mount on top tube with plastic electrical tie-straps available cheap at Radio Shack. I made bracket for speed sensor on Lefty Shock using 2" and 1" PVC tubing which fits perfectly around the shock -- also held on with electrical tie straps.
Bottom Line:I ride for serious cardiovascular improvement -- and fun. Now that I have the S-710, I cannot imagine training without it.

I recommend it to those who are deadly serious about getting fastest possible training effect -- you spent thousands on your bike and hundreds of hours a year riding -- now spend $280 to get the most out of that time/money investment. I would suggest a good book to tell you how to do that. I found "The Lance Amstrong Performance Program" to be the best overall among several books I bought for that purpose.

Casual and semi-serious riders can do just fine with a cheaper unit (and the same book mentioned above). My girlfriend uses the dirt-cheap Polar Beat heart monitor and a standard bike computer to good effect.

Weaknesses:None of the seperate parts seem designed to work together. The data wand doesn't sit well on the reciever wrist band. The reciever doesn't fit all that well on the handlebar mount.

Bottom Line:I've been using the S-710 for a month, and it makes dreary winter base training much less boring. Looking at the graphs after a ride lets you know what you really did. You see things like where you couldn't keep your cadence up on a climb. The included software makes it easy to keep a comprehensive training log. This thing is gonna be even more fun and useful when the real riding starts this year.

Note that NiteRider Digital headlights swamp the chest transmitter signal so that HR doesn't register. HID lights don't do this. Also, a friend with one of these needs Ba-Bump creme to make his work.
