    Ditching the can light is totally within rule #3 of course: Nothing underwater is worth dying for.

    Take a look around ScubaBoard... there are home built canister lights for apx $200. :) Can't wait to see if it's "DIR" hehehe (See my profile pic for example light.)

    wrt. trim: I can't exactly explain the mechanics of it, but if you don't keep your head back and your hands/arms up, you will slip out of trim. OTOH if you keep your head back, hands & arms up it will help bring your into or closer to flat trim.

    As I was taught, and what works for me, is that I keep my hands up to create a "horizon" for myself, so I need to keep my head back to be able to see over the "horizon".

    Of course if your weight distribution is *way* off, no postural changes will completely fix your trim.

    Considering canisters as ditchable weight goes back to the days when they used lead-acid batteries that actually weighed quite a bit. Ditching my canister nowadays, with its grand total of about 200g of weight underwater, wouldn't help much.

    I wouldn't ditch my canister either. If needed (e.g. wing won't hold gas), one of my teammates will be able to spare a few pounds of lift to help get me up

    I think the Explorer 13.5 weighs as much as a small cat though... maybe 7 or 8 eight lbs? I keep forgetting to swap out to the 9 for ocean dives!

    Go back for it. It's not like you diving in the middle of the Sargasso Sea...

    i dont think ditching my lithium battery would do much to help. I'd rather hang onto it

    If you've got a small can, it probably won't help you much to ditch it. Got a honkin SLA or a high capacity nimh? Perhaps.
