Hi Bigbore,
Got one for myslef last year after putting it off for a long time.
Very useful, heres a few points:
- you can mark a detailed trail in heavy forest cover
-allows you to get back to starting point even in the dark
-calculates speed , distance travelled, and elevation etc
-like having a moving "live" map with you
- great for marking where your kill may be from the truck
- can be used to mark a great fishing spot on a lake
- I take it on airplanes to follwow our route
- can be used to navigate in the car
- no heavier than a cell phone, can hang around your neck
- some models are very sensitive & can sense and mark movement as little as a few feet
-with a compass as a backup, you'll never get lost
I always take mine now and have become really comfortable with it. I think its a good tool. I have a fairly basic Garmin, $159 dollars.
If you never go far from the road, then maybe you don't need one, but you never know when you may venture into thick cover and follow an animal a fair distance. I think the best thing is to go with a hunter who uses one to see the possible benefits.
Good luck
