The Hot Hole replaces the existing hole light, or it can be added to any hard sided fish house. The Hot Hole is molded from ABS plastic and is fitted with a fan and light directed at your fishing hole. The design of the Hot Hole is simple, it redirects the warmer air a foot above the floor down into the hole sleeve to help fight re-freezing. An attached LED light strip provides illumination to monitor your hole. The fan and light functions are switched independently, and the unit is fused for the safety of your electrical system. The Hot Hole is powered by 12vdc. Mounting screws, electrical connectors and a spare fuse are included.
