DewZapper 3-4" OD dew heater for telescopes and finder scopes (52cm length, 11W)
DewZapper dew heaters are the high quality solution, with a genuine Nichrome wire heating element embedded in a silicon rubber substrate, for durability and moisture-resistance. The 22 awg silicon coated wires have a synthetic rubber outer sheath, which remains flexible even in very low temperatures reducing "cable pull" related tracking errors. The RCA power jacks are bonded with flexible glue and a heatshrink tube for strain relief. A high quality Velcro pad sewn onto an elasticated strap is included for easy fitment. An internal neoprene insulator directs heat into the optics so you won't waste any power.
There is simply no comparison with heaters which use thin audio cables and thin-film or "foil" heating elements, which are crimped to the wires, creating a failure point.
