Why choose this model?

The TD635LS brings together the three things most used on a night in the field: a wide field to find the animal, 640×512 resolution to observe it well and laser-measured distance to make the decision. It has the same body and the same weight as the TD435LS (374 g), but with 2.7 times as many pixels.

It is a good balance for those who hunt in mixed terrain. Those who mainly observe at long range in open country have a 50 mm lens in the TD650LS.
