Hi-Spy makes coin-operated binoculars and telescopes in both a standard model and an ADA (wheelchair accessible) model. We also make Special coin-operated models such as our memorial machine, customized height machine and wall-mounted machine. Once you decide on a coin model, you need to choose between 10X magnification and 20X magnification in a binocular or 20X and 35X magnification in a telescope.
You can purchase Hi-Sky products from NightSky Astronomy shop in the Middle East Region.
Magnification ratings are in comparison to the human eye. Therefore, 10X magnification is bringing the image 10X closer and 20X is 20X closer, etc.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.
