Topping our list as the best GPS for hunting is the Garmin eTrex Vista HCX. It'sa superb hunting GPS device to guide you as close in on whatever prey you're looking for, primarily because of its size, performance, and memory. It's small enough to fit in a pocket which means you don't have to keep it in a pack. As you know, you'll want to keep your movements as quiet and restricted as possible to keep from alerting your prey to your presence. Therefore, the ease of accessing this compact, lightweight, waterproof device by simply reaching in a pocket or even having it clipped to a belt enables you to remain as stealthy as possible. Even though it’s small, the bright color screen is still easy to read and the functions are easily learned and intuitive. Incidentally, if you're looking for all the best and most popular models available, you should read handheld GPS reviews catered to outdoor enthusiasts as well.
This handheld portable has an electronic compass which is vital especially for coordinating your plan with hunting partners so no one gets crossed up. Some GPS compasses only function when you're moving but the Vista HCX will work if you’re as fixed as a tree. The

MicroSD card slot means you can upload specific, topographic maps for whatever area you plan on hunting. This card that slips in and out (but it’s within the waterproof case when in the field) easily provides you with valuable extra memory which you can use to mark your sweet and lucky spot from prior hunts of the past years. A machine would never understand the concept of gravitating toward a place because of something called “good luck” but this device will get you there with a great deal of accuracy.
There’s a huge storage capacity for waypoints which means you'll never get turned around no matter how bad the weather gets or how baffled elusive prey can make you. Easily interchange the card if you're a hunter who goes on destination trips to track your prey in areas unknown to you. It’s the accuracy that bodes well for it too because if you have to leave your kill to go get assistance in dragging it out of there, you want to know exactly where it is on the return trip. The WAAS enabled Garmin gives you accuracy to within three meters and operates even in a deep tree canopy or narrow ravine. The long battery life (2 AAs give it 25 hours) will match the wait that many times is inevitable. The cost is roughly $300 which is part of the reason it’s at the top of the list.
