I just wonder whether using radar detector while riding is an effective way against ranger's radar gun.

One of the most powerful radar detector is Valentine V1 and it has a power consumption of about 3-5 Watts. (idling current is 225mA at ~12Volts) and we can easily power this thing with a battery pack. The whole thing won't be heavier than a pound or two.

Just wondering what kind of radar gun the rangers are equipped with. Are they the more sophisticated Ka band or just easily detected K-band or X-band radar? Do they use laser?

The more I think about this ticketing mountain biker thing, the more I think it's not right. How can they slap a single speed limit on all trails? Even our public roads have different speed limits for different sections.

Lol, reminded me of thus,....

Two British traffic patrol officers from North Berwick were involved in an unusual incident, while checking for speeding motorists on the A-1 Great North Road .
One of the officers (who are not named) used a hand-held radar device to check the speed of a vehicle approaching over the crest of a hill, and was surprised when the speed was recorded at over 300mph. The machine then stopped working and the officers were not able to reset it.
The radar had in fact latched on to a NATO Tornado fighter jet over the North Sea , which was engaged in a low-flying exercise over the Border district.
Back at police headquarters the chief constable fired off a stiff complaint to the RAF Liaison office.
Back came the reply in true laconic RAF style. 'Thank you for your message, which allows us to complete the file on this incident. You may be interested to know that the tactical computer in the Tornado had automatically locked on to your 'hostile radar equipment' and sent a jamming signal back to it. Furthermore, the Sidewinder Air-to-ground missiles aboard the fully-armed aircraft had also locked on to the target. Fortunately the Dutch pilot flying the Tornado responded to the missile status alert intelligently and was able to override the automatic protection system before the missile was launched'.


They would use laser, too much spread for radar at too small a target, but just lol at the very idea of testing cyclists for speed.....

Thanks for the story. Quite interesting.

So the rangers are actually using laser. Then there is no defense against it 'cause laser is by line-of-sight. YOu can't detect "strayed" laser around the corner.

the rangers arent using laser, its standard radar. I bought a battery powered escort solo for this purpose I just need to get around to designing and printing a mount for it

Story is total internet bullshit. Just the mention of "the Sidewinder Air-to-ground missiles" proves what a load of crap this whole story is.
Sidewinders are an air to air missile. They detect their targets through heat emissions, not radar. A radar wielding cop on the ground is not going to trigger any kind of response from one.

Re the RAF story. Radar might set off an alarm in the jet (being painted with radar), but Sidewinders are "air to air" missiles. Now would someone re-write it with Maverick air to ground missiles or HARM anti-radar missile and send it on it's way. If the RAF uses them. LOL. [9.0] Anti-Radar Missiles

As to original question, I'm thinking even a Valentine 1 won't be very effective at protecting you. Radar detectors work when the radar is on more often than its off. Prior to modern laser radars, cops would be sitting on the highway measuring car after car, sending tons of radar pings down the road, increasing the likelihood of your detector picking up a radar ping intended for someone else's car.

For rangers in the woods, there usually isn't enough traffic for that, I I'm thinking the detector will pick up the radar once, when it's pinging you.

Not that you should be speeding, but the best method would be the "slinky effect". One rider goes ahead, the other rider speeds to catch up. You'll need radios or cell phones. Remember, it's not the Ranger that counts, its not hitting other people out to enjoy the day. (hikers, horse riders, or other bikers.)

Lol of course it is - it is an amusing story though - would have first seen it on an email maybe 20 years ago now - though with slightly different details. Get happy!

I can't stand people spreading stories that are so patently false. The internet is full of this crap and suckers fall for it everyday.

Makes sense. Agree. So this leaves us pretty vulnerable prey out there by the rangers.

Exactly! Plan your descents to not piss off other trail users.

BTW LIDAR is the laser based equivalent of a radar gun. LEOs use both. It is harder to defeat LIDAR but for every measure there is always a countermeasure.

Surface to air weapon systems use both radar and laser tracking systems. Lots of stories from the good old boys I fly with. Including buzzing a Highway Patrol officer that had ticketed a young A4 sky hawk pilot on his way to work.

Apparently when the pilot returned to the spot the Highway patrol officer was hiding in his US govt supplied whip at 500 knots and 10 feet off the road: he knocked the billboard over the Highway Patrolman was hiding next too. 500 knots is fun. I can only imagine what it is like 10' off the ground in a fighter attack aircraft. This story was from nearly 40 years ago now, sadly that type of flying is discouraged by many branches of the modern military.

And yes sidewinder is a IR tracking air to air weapon system so the RAF story is a bit suspect.

Oh yeah? Once I talked to this guy in a bar who flew F14 tomcats and he told me this story where he called the tower and said "this is ghostrider requesting flyby" and the tower says "negative ghostrider the pattern is full" and he requests again and gets the same answer and then he does a fly by any way at like mach 4 just as the guy is getting his coffee, and the guy spills his coffee all over himself!!! He leftt to play volley ball and then went persian gulf later. Pretty neat. Pretty neat.

I think I met him before... Didn't he once go above the hard ceiling during training at Miramar?

Here is what you guys need to do. Take your ride computers off your bikes. Get rid of your Garmin and any other device that could give you an idea of what speed you are traveling at. Then when you get a ticket, fight it. Tell the judge you have no standard equipment on your bike that gives you an indication of speed. Tell the judge that unless Marin wants to mandate cycling computers then they cannot enforce speed rules. Fight it in any way you can to make it more costly to enforce. Make sure the ranger issuing the ticket gets dragged into court. At least that way they wont be out issuing tickets. Hit them where it hurts, when they run out of money the rangers won't be out there.

I saw a ranger writing a ticket today at Skeggs. Hopefully it was just a warning and not the full fine. But one thing is for sure, it was in the usual spot. So I've learned to keep an eye out when I hit that spot and ride full speed everywhere else. That spot is the fire road just above Blue Blossom, right around a corner so you don't see them until its too late. Of course, when they worked on that trail recently they added some nice little rises to entice you to go even faster and catch a little air. What scumbags.

When it goes to court, they'll tell you it's your responsibility to know how fast you were going. Your defense there is the same as the "I didn't know my speedometer was off". It doesn't work unfortuantely.
