Hi-Spy now makes bill-acceptor-operated binoculars and telescopes. They are identical to our coin-operated odels except for the bill-acceptance mechanism. Once you decide on a bill-acceptor model, you need to choose between 10X magnification and 20X magnification in a binocular and between 20X and 35X in a telescope.

Magnification ratings are in comparison to the human eye. Therefore, 10X magnification is bringing the image 10X closer and 20X is 20X closer, etc. Please see our magnification examples to view the difference. There is always a trade-off: the lower the magnification, the smaller the image but the wider the field of view. For example, if you want to see all the sailboats in the lake, use 10X - if you want to see just the people on one boat, use a higher magnification.
