I agree - I was quite surprised when I saw the thread that VMG by most GPS units was calculated by using the initial vector vs. current vector.

<br>I have an Etrex legend and have used the accessory "handlebar mount" mounted to my tiller (have to be carefull not to slap it when switching sides with the tiller extension). It does loose a substantial amount of waterproofing to the battery compartment this way and I have yet to find a better way to waterproof it with the handlebar mount (it replaces the stock battery cover that has the rubber seal - no seal with the new back). I'm open to any ideas.<br><br>[color:blue][b]Jake
