Most hunters would do just about anything to recover a deer they shot but can't find. For some hunters, that includes spending a chunk of change to tip the odds in their favor. Enter Leupold's upgraded handheld LTO thermals: The LTO-Tracker 2 and 2 HD. After testing the HD model all fall, I gotta say: This thing is awesome. The major improvement for this model over Leupold's first LTO is the Beacon mode, which distinguishes similar heat signatures to help you find your target. For example: If you turn on the thermal and discover that the trees outside your back door look like a heat map, you can press the Beacon button and it will zero out those readings. Next, pan the thermal over a critter, and it'll pop on the display. (For an example of this in action, check out our video here.) The rest of the controls are just as easy, with one button to zoom, and third to power the unit on/off and toggle between the six color modes. The prices might be a little easier to swallow when you consider how much grief it could save you down the road, but before you shell out, check the regs in your state. Thermals are illegal to use while hunting game animals in most places, and are sometimes outlawed for recovery, too. The Tracker 2 HD is listed at $1,560, and Tracker 2 is listed at $1,040. —N.K.
