Tree Cover Questions


Recommended Posts

What would you suggest as the most affordable GPS unit that can deal with tree cover? I'm not talking thick deep-woods canopy, but rather, partially open sky directly overhead but with a lot of tall trees around. I don't know how sensitive lower-end GPS units are to this sort of obstruction. How much open sky do you have to have in order to get a clear lock on satellites with one of the lower-end units?

For heavier canopy, probably the Lowrance Ifinder and the Magellan Sportrak are the most affordable (around $140). From the Garmin line, the GPS 72 and 76 are the cheapest units with great sensitivity.


For lighter canopy, indeed any unit will be fine, but I believe (from what I read) that the Gekos are somewhat better than the Etrexes. The Etrexes are probably the least sensitive units on the market.
