Dew-Not was founded by John Marstiller, the author of six United States patents and multiple international patents related to resistance heaters and innovations in flexible electrical circuitry. John has been designing and manufacturing thin film heating elements for over 30 years, and has used these products in home heating and military thermal imaging applications as well as in his highly regarded telescope heaters.

High Point recommends Dew-Not heaters. Why? Because they draw a lot less power and cost significantly less than other telescope heaters on the market. Drawing less power means your battery will last longer! Dew-Not heaters are very well made right here in the USA. Each strip has a standard plug that will fit most dew controllers, including the one manufactured by Dew-Not!

The Dew-Not Dual Channel Controller is also made in the USA (we love that!). It sports two outputs per channel, and you can control the output (from zero to 100%) on each channel. The Dew-Not microprocessor-based controller has a two stage low battery indicator, and is virtually RFI free.
