looking for Speed Gps for MTB

I haven't personally used this one, but it seems good.

cadence is pretty much useless on a mountain bike, unless you use your mtb on the road.

an Edge 705 from Garmin

I use the Edge 305. Love it. Small, light, display big enough to see when you are actually riding. Speed sensor is either GPS or wheel sensor.

i second the Garmin 305. Great tool! I have multiple readings on the display all the time:
actual speed,avg. speed,heartrate,time,stopwatch,+ elevation done ,actual height, % of grade, distance

I find the 705 too bulky and all those additional Gimmicks with maps etc aren't working anyway if you are riding in the forest or bushes....two of my friends aren't too lucky with the 705. One of them went back to the 305.

Thanks all, those are some great answers!
Anybody uses Polar?

I think I"ll go for the Edge 305
just have to find it for a good price in the U.S.
Thanks again

Well mine in working just fine, never had problems with it and maps are quite usefull (but I don't have to say that as it's obvious).

I can't understand though why Garmin don't use cadence sensor for speed reading. Instead it uses only GPS unit (after it fixes itselt). While it's not as accurate as normal cycling computer, it also gives you bizzare readings while riding in the forest.

Check Bestbuy - they had them on clearance a week ago for pretty cheap. The Edge 205 is also an option - basically the same without heartrate and cadence.

I found a used 305 on ebay. It has worked great for a couple of years. The battery seems to have a great life in these units. If anything goes wrong - Garmin has a blanket repair service for about $75 or so. They just replace it with another reconditioned unit. Very nice service.

Maps are pretty good. A little small, but very useful. Can't to topo, but easy to set waypoints and find your way.

The antenna seems to be very accurate, even in the woods. the GPS itself starts up and locks on amazingly fast too.
