Get a waterproof garmin unit, a Vista HcX or the likes.
Some models even have scout mode where you can mark a perimeter, but almost all of them offer tracking.
I have used my Lowrance quite a few times, once even a heavy rain on a trek, and it works like a charm.
Make sure you get a unit which is waterproof upto 3 feet or something.
Also do not use rechargable batteries, but get good Duracell for your unit, most units last 12-14 hours on a pair of batteries. |
