Even though I hunt the same area, same piece of timber for 6 years now. I still take along my GPS and use it religiously. I always mark where the horse it tied up, everyday. It has helped me find the shortest way to my elk on several occasions now. The timber I hunt is very rolling ground with lots of deadfall and most every knoll looks just like the next one. It has also helped me to find the quickest and shortes way back to the horse more than once. I use it deer hunting and elk hunting both. I have never had a problem in the canopy geting a signal, just took a little longer to get the signal.
