Thermalution® Blue Grade is the first power heated undersuit which utilizes the Close Proximity Sensor (CPS) control system. It is an intermediate model best suited for divers who wish to dive deeper into the ocean.
No one enjoys diving while it's cold and miserable. If you are feeling a little blue underwater, why not let the Thermalution Blue Grade fix that? Armed with two lithium polymer batteries, this garment will turn up the heat for up to 120 minutes underwater.
Introducing the new Close Proximity Sensor control system, the Thermalution Blue Grade can be turned on and off with a simple tap. Avoid having to press clumsy buttons through your gloves with this new simple control system, making your diving experience even smoother.
