Garmin Alpha XL Navigator Features The Garmin Alpha XL Navigator is designed around a large easy-to-read 10 inch touchscreen that displays mapping and dog location data in a format far easier to interpret than a small handheld screen. Its 1280x800 resolution keeps map details and dog tracking icons crisp and legible even at a glance while moving through the field. The unit is capable of tracking and monitoring up to 20 dogs simultaneously making it a practical tool for hunters running large packs across wide open or heavily wooded terrain. Built to handle off-road use the Alpha XL Navigator is constructed to withstand the bumps and exposure that come with hard hunting conditions. A rechargeable lithium-ion battery delivers up to 20 hours of runtime on a single charge giving hunters enough endurance for a full day in the field without needing a mid-hunt recharge. 64GB of internal memory provides ample storage for detailed topographic and property mapping data letting hunters navigate unfamiliar terrain with confidence. The black finish keeps the unit low-profile for use in a variety of hunting environments. For hunters who need reliable large-screen dog tracking and navigation in one rugged package the Garmin Alpha XL Navigator is available for sale at GrabAGun.
