Product Description

The Thermalution® Deep Diver 70m Undersuit is the world’s only first and only battery heated wetsuit product for scuba divers.  Tested to depths up to 250ft, the 70M Thermalution is the perfect tool to fight against the dreaded thermocline.  Powered by two 7.4 volt Lithium Polymer batteries and worn under your current scuba wetsuit, Thermalution® turns your existing wetsuit into a heated wetsuit!  As water enters the wetsuit on a dive, it circulates throughout your wetsuit and over the Thermalution.  This results in an increased water temperature in your wetsuit, keeping your core body temperature warmer, longer. 

Nearly identical to the core 15m model, the only difference lies in the temperature control unit, which is designed to withhold water pressures of up to 250ft below the surface!  Thermalution can be taken with divers on the longest and deepest of dives, helping to warm you when your body alone cannot produce enough heat to keep you warm throughout the dive.  With three levels of adjustable heat, your Thermalution heated wetsuit can be adjusted with the push of a button, giving you the warmth you need when you dive deep with the ability to turn off quickly for that warmer safety stop.

 

Similar to any base layer clothing (like Under Armor®) Thermalution Undersuits can be worn beneath any wetsuit, dry suit, or jacket. It's most effective to wear directly on your skin.

Wearing beneath a wetsuit

Thermal protection of a wetsuit is limited to insulate your body and minimize heat loss. The thicker the neoprene, the warmer you'll feel, but you may get extremely exhausted by putting a thick wetsuit on. With our Thermalution® Power Heated Undersuit, you can say good-bye to a thick wetsuit and enjoy a fun cold water sport with a thinner wetsuit, because Thermlation generates heat instead of only been able to reduce heat loss. By wearing Thermalution® Power Heated Undersuit beneath your wetsuit it distributes the heat through whole body by the water underneath your wetsuit.

Battery and Controller

Thermalution Heated Undersuits use two 7.4 volt Lithium Polymer batteries. Battery Size: 4x2x0.5 Inches.

These are the same type of batteries found in your mobile phone or mp3 player. There is no danger of radiation, electric shock or explosion from these batteries. Batteries are compact and lightweight and are positioned outside of the undersuit at the sides of the chest, under the arms. It offers maximum freedom of movement and it's easy to change batteries.

Thermalution micro controllers are easy to use. To turn on the undersuit push and hold button for 2 sec. On start up it displays a green light and starts temperature on low. Push once more to change to medium temperature with an orange light indication and once more to change to high with a red light indication. To turn the undersuit off simply push and hold button for 2 sec.

  1. Amazing warmth!

    Posted by Melissa Guzior on 31st Oct 2016

    This is a amazing product! Wore this under my 7mm wet suit in Guadalupe island diving with the Great White Sharks. Cold water! Was able to stay down longer and get great photos of the experience. I am usually shivering underwater after 45 minutes....but, not in this shirt! Would recommend to all. Charges easily and lasts a long time.


  2. Game changer for coldwater drysuit diving

    Posted by Bonnie on 9th May 2016

    I bought this to wear under my drysuit while diving in the winter in the Pacific Northwest. It is great! It has nearly doubled the length of my dives. Previously I could go about 30 minutes before I was so cold that that was all I was thinking about. I just spent a week in North Vancouver Island and all my dives were 50+ minutes. I always kept it on low. I can't imagine turning it up higher if you are wearing it under a drysuit. I had to wear 2 shirts under it as well. When I went with only one shirt, my back got burned.....literally.
    The battery life was okay on low, but if we were out on the boat for back to back dives, the shirt would usually die sometime during the second dive. So I am buying a second set of batteries for back up.


  3. She's hooked

    Posted by Mark on 20th Apr 2016

    My wife is always cold, and she's been using this shirt since 2012. For her, it makes the difference between diving and not. We were on a liveaboard where the crew poured warm water into wetsuits at the end of a night dive. She was the only one who didn't ooh and aah; she said it was what the heated shirt does all dive.

    After her shirt stopped working on our last trip, she contacted Matt, who offered to repair her broken shirt, sell her a new one with no batteries, or even sell her a used demo shirt. She went for both the repair and the demo shirt, so that she's never without the shirt again--and can loan out the spare to skeptics.

    The great customer service is almost as good as being warm throughout a dive.


  4. Never Know if It is going to work

    Posted by Linda Kruszka on 19th Jan 2016

    My heated vest is great when it works. The last two times it worked great. I find the batteries do not hold the charge for as long as advertised. I have the setting on low. The last time, there was a flashing red light. Nowhere on the web site or in the materials I have tells me what this means. More FAQ's or tech support should be available. The idea is awesome, however there need to be some upgrades and tweaks.


  5. Guadalupe cage diving

    Posted by Unknown on 20th Dec 2015

    The white shark cage diving of Guadalupe Island in colder water and not generating much body heat I found this product great for keeping warm. Thanks


  6. Works Great!

    Posted by Unknown on 17th Nov 2015

    Does everything as advertised. Test it for power duration and at Low Heat, the batteries lasted 2 hours and 23 minutes. I have only used it twice, but it has functioned perfectly.


  7. Nice

  8. Theremalution 70M - only modestly warm

    Posted by Brad Wright on 27th Sep 2015

    I bought this recently and used it for the first time on a dive trip to Galapagos two weeks ago. I have to say I wasn’t impressed. I was wearing it under a 5mm wetsuit and while it provided some warmth it in no way provided me the kind of relief from the cold I expected. It was a small localized heat, even on high. For the price I expected a lot more.

    I’m unsure what to do with it now as it’s hardly worth the weight in baggage for the warmth it supplied.

    Another diver expressed the same feelings when diving wet. He however had the wireless one and could use it under a drysuit where he said it was considerably more effective.

    Overall I’m disappointed.


  9. works great but quality an issue

    Posted by Unknown on 26th Sep 2015

    I used the wet suit for 12 days of diving in the Maldives and it worked great. Really kept my core warm the whole time. However, the thread on both the battery pockets has broken. Not likely to last through another dive trip without repair. I showed it to a tailor and was told the product was made with the wrong stitch for the type of fabric and pockets need to be re-sewn with a stretch stitch to prevent future tearing. For a product this expensive the quality is unacceptable.


  10. Extended my diving options

    Posted by Ted on 16th Sep 2015

    Just used the heated shirt for the first time in a cenote dive in Mexico. I am alway the one who comes up cold and blue. This time I was warm and smiling while the others were shivering to get warm. The shirt will certainly allow me to do dives I could would not consider before. Before my trip I had some questions and customer support was prompt and thorough. Great product.
