    A while, bought so many they've lasted ages!

    Lol
    Are they not for emergency use . Its not like your using one for every dive .

    Divers being green ffs.

    I have used the Kent Tooling ones for a while and quite like them. If I'm closed circuit they're my DSMB of choice as wasting bailout seems silly to me but if I'm OC, which means I'm pretty shallow, I'll use an old-fashioned DSMB and blow it up with my exhaled gas.

    As others have said, buy spare mechanisms as they fail. A lot. Don't undo the cylinder underwater unless you really have to and that will help protect the mechanism. The last one I bought came with some quite detailed care instructions (most of which I've forgotten).

    Buy cylinders from catering companies rather than diving companies and/or cycling companies as they're much more reasonable. Also, buy in bulk. Occasionally a cylinder will fail to fire.

    To satisfy my green credentials I always bring used cylinders home to be recycled. It's not that green but better than chucking them in a bin. I try not to worry about the loss of the captured CO2.

    My only gripes are:
    1. my old DSMB developed a hole where it rubbed on the mechanism in my pocket. I fixed it with some duct tape so it holds air albeit not as firm as a new one
    2. the bungee on the new DSMB fell off so I replaced it with a loop of bungee through the D ring.
    3. the mechanism is a type 2 whereas there was an incompatible type 3 supplied by the chap that had his warehouse burn down a while back. I now have a couple of serviceable DSMBs without mechanisms.

    What a lot of words to support your needless waste of resources!

    I have a CO2 blob (as backup) and I clean and check the mechanism (they are shit and will fail) and I fire it once or twice a year to confirm it works. It also has LP fill just in case. The last time it was used my backup by necessity was in 2015 (the day after I collected it from Aquatec) and since then it is mostly a maintained pocket object (now the Aqua elevation version).

    For dives where I expect to deploy an SMB my crack bottle is used. This is filled from the same source as the suit bottle and I fail to see why any alternative is actually better!

    Hot air is never is short supply in the diving world but for sending an SMB from depth I'd rather let compressed air do the work... and provide me with a lift from the seabed so I can keep the middle-sized bubbles in sight until the SMB hits the surface and I have to start winding <yawn>.

    Handy hint- push a blob of silicone grease into the hole before you screw the cartridge in. Then when you fire it, the grease gets spattered over the internal mechanism. Never had to change one yet.
    I have nothing to do with BSAC any more apart from being a muggle member. So anything I write on here is likely to be complete bollocks. Hooray!
