Description
Main Features
- LED battery status indication around the Piezo switch. Eliminates guessing battery charge and extends the life of the battery by only charging when needed.
- Constant heat output from start to finish of battery
- Heat does not decrease with battery level; very important for optimal decompression
- 5 heat levels for range of comfort in water of -3c to 20c (23F° – 68°F)
- Piezo switch control for both on/off & changing heat levels
- Eliminates the high failure rate of boot switches
- Mechanical switch does not have to be toggled to adjust levels
- LED indicator for battery status indication (high/green, medium/yellow, low/red), power on/off, & heat level setting
- Can be used independently or with lights on the same battery
- Small, compact & light weight design
Compatibility
- Compatible with all UWLD Latchless Batteries
- Comes standard with the stack cap for the Latchless Battery
- Stack cap allows the controller to be added or removed with ease
- Industry standard wetmate E/O connection
- Supports all 12v heated under garments
- Incompatible with lights heads run downstream of the controller
- Incompatible with non-UWLD battery canisters
The Science
- Research has shown optimal decompression occurs when warm
- The body may be cool on descent, but should be warm on ascent
- Dr. Neal Pollock from DAN discusses Thermal Physiology and how temperature effects decompression in Broadcast 1 &Broadcast 2
- Warm is 36C (96°F) | Cool is 27C (81°F)
- Being warm at the beginning of the dive increases the uptake of inert gas
- Being cold at decompression confounds decompression
Why UWLD?
- Leverage existing investment in light and batteries
- Advanced technology ensures consistent heat at the most crucial time, the end of the dive. Traditional solutions offer only 75% of heat at bottom low end of the battery.
- Double O-Ring Seal
- LED feedback removes guessing of set heat levels
- LED battery level indication
Battery Burn Time
- The controller runs slightly above undergarments rated wattage on high
- To calculate burn times, UWLD suggest that 110% of wattage be used. If a diver has a 60W vest, they should calculate burn time for 66W for the high setting.
- Each level drops the power consumption by 20%; for a 60w vest: Level 4 = 53W; Level 3 = 40w, Level 2 = 26.5W, and Level 1 = 13W.
- With a light, add the light and vest wattage then divide by canister rating:
- 32W (LD-40) 60W vest(X 110%)= 96W /124Wh (canister rating)
- Both on high yields 1 hour on a 124 wh canister
- Light on high, vest on low yields 2.5 hours on a 124 wh canister
- 32W (LD-40) 60W vest(X 110%)= 96W /124Wh (canister rating)
