Like the model we have carried for years (78D02.02
), this lets you see people and objects in complete darkness. It works exactly the same but has two significant enhancements. First the objective lens is twice the diameter which gives it 3½ times the light gathering capacity. Second, it’s magnification power is twice as great (4X instead of 2X). (The field of view is therefore, slightly reduced.) Although bigger physically, as you can see, it only weighs 2 oz. more. The extra cost is well worthwhile for the enhanced input.
