These dew heater straps are designed to work with 12V power supplies and produce heat to keep dew off of the objective lens or eyepiece. A simple design but astonishingly good quality materials and finishing.

It's main advantage is its low power consumption (0.2W/cm). It's made to be easily wrapped and held in place with the attached elasticated Velcro strap. 

Comes with 2m of flexible silicone cable with male RCA/Phono connector.  Current draw is dependent on size and at 12V

Compatible with all popular controllers, but work especially well with our own.

Thankyou 5 product stars
"Hi all, Thanks for quickly sending the eyepiece warmer. I was very impressed with the speed with which it chased the fogging away on my eyepieces. I used my FLIR camera to take a heat image of my rig with the heaters on. Cheers, Bryan" Bryan Dawson - 11/09/2018
