The Orion Dew Zapper Heating Band for 3" - 5" small aperture telescope is part of the larger Dew Zapper Pro 4-Channel Dew Prevention System. The heating band is highly power efficient. A 10-amp fuse in the control module prevents any mishaps from electrical surges or reversed polarity.
Unlike competing dew-prevention systems, the Dew Zapper Pro's heating band has right-angle cable connections to reduce cable strain and provide a tighter fit. Hook-and-loop fasteners hold the bands snugly around your instrument and accessories. It comes with a 6'-long cable that plugs into the control module via an RCA-type connector. Removable caps are included to protect any unused ports from exposure to the elements.
