Be twice as effective with a Leupold® LTO-Tracker HD Thermal Viewer in your pack. First, use it to scout your area to avoid spooking game on the way to your stand and then get a bead on where your downed game ended up. Follow blood trails with a 2nd-generation thermal sensor that picks up signatures out to 750 yards and offers a 390x390 pixel full-circle display. Customize the contrast of your images with the choice of 8 palette colors and dimmable display. Automatic shut off kicks in after 15 minutes of inactivity so you don't waste battery life.
