GPS Unit for Speed Question

[CaptPJB]

Seems like the Garmin Etrex GPS is favored to get speed probably because of its price around of $50-60 on Ebay. Has any one tried using the small cheap Tom Tom or Garmin units to get a max speed reading?

Seems like if it would work you could get dual use out of one, A Nav unit for the car and Max speed unit for the boat.

they would probably work fine just make sure the are somewhat water proof or in a good ziploc bag

Good thing about the Garmin Etrex is its water proof.Its worth the money.

I use a forerunner 301, GREAT small GPS about the size of a AA4 cell nimh rx pack. Light weight waterproof and A LOT smaller the a etrex I love mine https://buy.garmin.com/shop/shop.do?pID=270&ra=true
