Technical divers using heated vests or gloves often face the challenge of fixed power output. Once set, the device delivers the same power throughout the dive, regardless of changi ng water temperature conditions. What feels comfortable at 70 meters can quickly become too hot during decompression stops. To address this, Bigblue developed the EO Heat Controller in collaboration with Patrick Widmann. This compact unit sits between the battery pack and the device, giving divers precise control over power delivery. The system provides three selectable output levels: 100% indicated by red, 50% indicated by yellow, and 25% indicated by blue. This allows maximum flexibility to adapt to the environment in real time. Two models are available. The EO Heat Controller I is an inline unit for single-device control, while the Y model splits power to two devices, with each output cable individually adjustable left and right for independent control.
