Anyone know of a good preferably small gps unit that will hold highest speed and maybe even altitude?I've seen the ones that holkd speed reading .Thanks[&:]

I own the Garmin Geko and am very pleased with it. It holds max speed but not altitude. It would be very interesting to see an altitude reading. The fastest speed it has clocked so far was from a flying wing @ 137km/h.

Thanks so much.Thats what I'll probably get.

Thats the version I have. Apparently the newer 301 is better. May have altitude features, check it out

I have the Garmin Foretrex, it does top speed but not sure about the altitude. But it is smaller and lighter than the gecko. Less weight will slow your boat down less.

Wow, do you have a link? The geko is 3.1oz with batteries

Ryan

i know that this isnt a altuted but here
its cheap

Hey i looked up bike computers and found all the ones i looked at had to recieve info from a frame mounted sensor that counts a magnets passing by that's attached to the wheel.the only difference i could tell in the cheap and expensive one's was the use of wireless sensors.These i'm afraid won't help us boat and airplane nut's , but thanks for the info anyways.

Ya most bike spedo's won't even work for rc cars since they need at least a 10 inch tire. For boats it is impossible to use a magnet/transistor setup.

I have the garmin etrex small and waterproof ... walmart website for 79 bucks . best price around.

I also have the Etrex and the Foretrex, the Foretrex is a little more $$ around $109 but its WAY smaller and MUCH lighter. On boats 30" and less this will make a big difference in your speed reading.
