RE: Coolest gadget?
Handheld GPS.... (Garmin 60CSx)
I hunt public land and always had guys going to my locations off my markers. Now I just plot the location and track the route and walk right in not more than 10 feet off the original trail I created in the dark. I have to say its the best confidence builder to go in deeper and explore more than anything I have ever used. I would be lost without it now in my woods.
FYI my walk ins are on average over a mile.
