    BCD TUSA Valve cap removal

    Hi. I received a TUSA BCD. The valve cap has the cord broken and missed valve knob. I was trying to remove the valve cap but I couldn't. The valve cap moves a littel freely in both directions, but it seems that it's not threaded as all other brands. Does any one know how to remove the valve cap...

    Diving the Thistlegorm no liveaboard

    Hi all. I and my dive buddy and friend, and perhaps one more diver want to dive multiple times the Thistlegorm. We do not plan to dive from a liveaboard as the Thistlegorm seems to be dived only two times. We want to make perhaps 4 day dives and one or two night dives in that wreck. Also, some...

    Dive Trip to Bonaire, staying in Buddy Dive

    I've just reserved a dive trip to Bonaire. We will stay in Buddy Dive. The deal includes a truck for every 4 divers. The question is what do divers do with the truck keys while diving. Truck keys can be submerged ? or we need to by a dry case ? Dry cases are also included with the truck rental ?

    Reyson regulator (Japan) service manual

    I was offered for a killer price an almost new Reyson reg set. I guess that the first stage is a Reyson RS01-j YOKE and the two second stages are also Reyson but no clue of the model. It also has a Coltri Sub SPG. I was trying to find info about that brand, but only side comments. I only could...

It's a little separated from the neoprene. I cannot find a way to disassemble it and I do not want to do too much force and break...

    As per this thread New Dacor Extreme 1st and Pacer XLE 2nd..in need of a service kit for both! DACOR came with a device called Purge Button Depressor installed in the second stage.

    Advice not to break 2nd stage case with sticky Inlet Fitting

    Several dive friends gave me regulators to overhaul because they have them and not dived it since several years. All threads were sticky and with plastic 2nd stages the risk to crack the case trying to disassemble the valve is too high. This happened to me in two ocassions. In the first the case...

    Poor's man mask

    Yes, you all can tell me all sort of insults, but here am I. Someone gave me a Mares Wahoo mask that had both strap hangers (I don't know the right name) broken. Those hangers are part of the silicone skirt of the mask. A terrible design. The mask was useless. The right place for it was the...

    Why SPGs got dirt inside ?

    I've seen lots of SPGs that got dirt inside, full functional, no water inside, but making them useless as they cannot be read. SPGs are bourdon type manometer, so the air that comes from the tank goes to a closed bended tube inside. The interior of the SPG is also sealed to the environment. So...

I can remove the designed mouth piece from a cube and have a two parts mold. I don't know the adecuate shore hardness that a silicone...

    How to disassemble a SI Tech exhaust valve

    Hi, the SI Tech exhaust valve of my Drysuit is leaking. I could remove from the drysuit but I do not know how to disassemble it. The valve rotates as if it has sand in it (it's a used DS). I have the SI Tech brochure, but there is no disassemble instructions. Any help is much appreciated.

    I'm not lucky with UW cameras

    I'm just demoralized. My first UW camera was a Canon A570IS. I bought the Canon OEM UW Housing. Too bulky and always with my heart in my mouth if something goes wrong, I mean a flooding. I switched to the INTOVA Sport HD. I wanted to video and the proposal on a camera within a housing was...
