One of the biggest issues with current heated systems is the diminishing heat output as battery life dwindles. The UW Light Dude heat controller’s innovative design offers functionality for a wide range of diving that requires heated undergarments and addresses the need for warmth when you need it most – longer duration dives.
There are 5 power settings and each setting gives the same heat output regardless of the battery voltage. Research has shown that cooling on the ascent/decompression portion of the dive has a negative affect on decompression. Dr. Neal Pollock, from DAN, has summarized a number of studies that make this point, he has 2 YouTube broadcasts covering this information. Broadcast 1, Broadcast 2. Optimal for decompression is to be cool on the descent/bottom portion of the dive and warm on the ascent/decompression part of the dive. Other systems cool off when the voltage drops from the battery canister the heat output also drops. Our 5 heat settings are spaced to give heat output from -3c to 20c (23F° — 68°F ) water.
The controller comes standard with a UWLD Stack Cap allowing it to be used as a single on a battery, with the included blanking cap, or with a UWLD light canister cap stacked on top of the stack cap. Our other caps are available as well.
