A smarter way to stay warm on your dive.
LED Ring Indication
New LED battery status and heat level indication ring.
5 Power Levels
Select from 5 power levels to control comfort and burn time.
Constant Temperature
Innovative design ensures constant heat levels across battery duration.
Integrated or Stand Alone
Share you light power source, or run it independently.
Highly Efficient
Highly efficient design ensures that no battery power goes to waste.
LED Power Indicator
Power level is indicated by a piezo integrated LED signal.
Using a heating solution
Heating solutions are a simple and effective way to stay warm in cold water or on long dives. In conjunction with effective thermal undergarments, they enable a diver to manage thermal capacity and therefore optimise decompression.
One problem with traditional heated vested battery setups, is that as the battery runs down, so does the voltage in the battery. This means that at the end of the dive, when you need heating the most, your vest will be at the coolest temperature.
Leveraging the higher voltage of Light Dude batteries, as well as our heat controller with variable power output, you can maintain a constant temperature to the end of your dive, or even turn it up at the end!
Heat Controller System
From $695
Main Features
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, no moving parts
LED battery status indication around the Piezo switch. Eliminates guessing battery charge and extends the life of the battery by only charging when needed.
Piezo switch does not have to be toggled to adjust levels
LED indicator for 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 Gen5 battery packs
Comes standard with the stack cap for the Gen5 battery
Stack cap allows the controller to be added or removed with ease
Industry standard wetmate E/O connection
Supports all 12v heated undergarments
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?
Advanced technology ensures consistent heat at the most crucial time, the end of the dive.
Traditional solutions offer only 75% of heat at the low end of the battery voltage.
Double O-Ring Seal
LED feedback removes guessing of set heat levels
Leverage existing investment in Light Dude light and batteries
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:
30W (LD-35) + 60W vest(X 110%)= 96W /160Wh (canister rating)
Both on high yields 1.66 hours on a tall canister
Light on high, vest on low yields 3.7 hours on a tall canister
