So I bought this pile of plumbing parts...

    SOME? I find it very hard to believe tbh. You'd need to throw the scooter in climbing and or descending turns on the trigger or run it very slowly.

    You can do exactly the same on OC too, that doesn't mean you should. If you come off the trigger you have it all to sort out. x

    I never said I hooned straight through at top speed. Of course I was going slowly.

    Youre not getting my point. Have you dived a CCR?

    I'm still not convinced. If you have to come off the trigger the scooter becomes luggage.

    No I haven't. The point you're making is that the scooter drags you along meaning you don't have to worry about your buoyancy. In the same way that people who have to keep swimming and constant finning aren't aware they are negatively bouyant, in the same way that it also works on OC. Unless the scooter allows you to somehow defy physics, this is how it works. x

    Or a valuable source of inertia/momentum ;)

    Except that's not the point I was trying to make.
    Of course you maintain concern about your buoyancy but it allows you to quickly ride over/under objects in the same way that you'd temporarily use lung control to do the same on open circuit.

    I'm not riding around using the scooter for 'buoyancy' for the entire dive.

    Oh, so you don't you fancy doing it at top speed on the Piranha? I'll bring the GoPro if you do :)

    Also useful if there is a lot of current on the shotline, like that time on the Markgraf where others were knackered when they reached the bottom, or heading back up due to CO2 alarms.

    I do agree that, after significant change in depth, it is important to establish neutral buoyancy (and to let the ppo2 drop if it has been a rapid decent) before getting back on the trigger.

    and in a tight space that just tends to end up as CLANG!

    I'm not sure what the point was then.

    You can do and many people do the exact same thing on OC. Generally its pointless temporarily adjusting your bouyancy if its only for very short periods as the scooter irrespective if you are on OC or CCR will drag you where its pointed.


    Its good to know ;) I didn't expect otherwise tbh :D x

    Scooters are great for Deco if there is current or if there is a nearby reef or something interesting to hoon about :D x

    I've been in tighter spaces than that box.

    Dave will vouch for that ;)

    They are great for Scapa and on big wrecks but not so useful on smaller wrecks. They do make NDAC more acceptable as they remove the need to haul stuff onto the pontoon and it is fun whizzing over the cliff and down, overtaking the sensible divers :)

    Yeah, you were in a bit of a jam. Good thing you had a reliable dive buddy who never abandoned you :)

    Oh yes. Very much so.

    Even with the Halo on I was overweighted with no lead. The 5mm BP should see me good for sea dives and I'll be trying my 3mm and Ally BPs next time I'm in a puddle.

    There's some fettling still to do; those stupid d-rings need cutting off for a start. :mad:

    It's interesting seeing your fins telling their story. Normally they'll be perfectly still, but as soon as you add the task loading, they wibble around like nobody's business.
