Just ordered a garmin gpsmap 62s on close out pricing as the new 64 series is on the way to stores. I'm going to pair it with the huntgps chip for colorado....never needed one of these in texas, just drove to the stand which was on a road or on a pipeline, lol. I used the gpsmap stuff on my offshore boat when we lived on the coast and if this hand held is even remotely related it should be a good piece.
Try to put your tree stand in a tree with plenty of background cover, keep the prevailing winds for that time of the year to your face, and take care of those pesky squeaks and creaks your stand may have developed while sitting in the shed. A good treestand lube can be made by heating petroleum jelly until it reaches a liquid form. Some hunters have reported success by including a cover scent in this mixture before applying it to their stands.
