    Canister lights and interference with AI transmitters

    I do not know what Orca Torch is using internally, so this comment does not relate directly to their product. As Grantctobin said, transmitters can have their signal interrupted with Pulse Width Modulation (PWM). My heat controller as well as most others use PWM. Many light manufacturers also...

    Discussion of best practices for advancing in cave diving (moved from A&I JB thread)

    If any instructor is requiring CCR removal, passage through a restriction, and put the CCR back on for a CCR Cave Crossover class then do not use that instructor. Before SM CCR was a thing I modified a BM CCR to be removed, floated in front of me while on the loop, and put back on to pass SM...

    Breast Cancer Awareness Limited Edition "Pink"

    The last pink heat controller shipped out today. If anyone is still wanting one you should call a UWLD dealer ASAP to see if they have any left. Dealers and I still have some of the pink LD-40's as well, however they are getting down to the last ones as well. I want to thank everyone that has...

    Breast Cancer Awareness Limited Edition "Pink"

    I don't know if I will do another run of pink in future years. I highly doubt I will do other colors than the UWLD blue and the breast cancer awareness pink.

    Converse Chucks

    My wife dives Chucks, the reason is that she has very narrow feet and the dry suit boots available are too wide. She has been cave diving for 13 years and has never had an issue with the laces. BTW, rock boots and other dry suit boots also have laces, the Pinnacle boots that I wear (very wide...

    Flooded Light, new light recommendations?

    In your defense, IIRC, you have not had the new MIL spec cord until now. If you need a longer cord you only need to ask, I do custom cord lengths all the time. If you are pulling the cord tight when you reach your arm out it should probably be lengthened an inch or two. If you want that done...

    4S3P Battery Pack

    FYI, any cells packaged together form a pack. All LiION battery packs must be UN/DOT 38.3 certified for commercial air travel. The limit for carry on is 160wh. IMHO, taking home brew packs on an aircraft is not a good idea.

    Thank You

    Some people like to switch from the Goodman to another clip on their helmet, scooter, etc.

    Thank You

    I want to thank everyone for making 2021 the best year UWLD has ever had. I also want to thank everyone for their patience as we were backordered the entire year. 2022 has kept the same pace of orders as last year. The good news is that all orders have shipped out and we are now building...

    Help on Canister for Heater/Light

    Before I left for our T-give diving I had all orders shipped. I didn't get to build inventory however. Present orders that came in over the T-give holiday should ship this week. An order that came in today should ship next week. Yes, I've been back ordered for the entire year however the wait...

    Help on Canister for Heater/Light

    Rjack, Who did you order the canister from? I was caught up on all orders before I left for our T-give dive trip. I've only had two orders for canister only, both came in November, and they shipped the next week. I have been back ordered since the end of 2020 and have not been able to build...

    Planning full cave training in Mexico - any recommendations?

    Roger Williams is a top notch instructor. He and his wife, Nellie, are great people that run a cave diver BnB. My wife and I have stayed with them and have paid Roger as a guide while we were there. XOC-Ha | Cave Divers BnB Mexico

    LP50s Modular Valves required?

    Who at CA told you they don't have them? I'm sure that they stock them, they order them from me all the time.

    Seeking pressure chamber recommendations

    Do you have a link to Global's pressure pot? I tried to find it myself with no joy.

    Dry cave and UW cave helmet mounted light options??

    I use a Piezo that is made to my specifications to keep accidental turn on/off from happening. My Piezo requires a small amount of pressure to activate, not touch contact, and a full 3 seconds of pressure to turn the light on/off.
