Which XDeep BCD should I get? Help me with my analysis paralysis

1. Interesting app - what is it?
2. That's a huge amount of lead, are you sure? Just for reference, with a very similar setup I might use ~2kgs

<EDIT> I made some back of the envelope, hand-waving estimates a little while ago Apeks WTX D18

1. Scuba buoyancy calculator
2. Yes to be conservative I based it on what I used with a 7mm. So its:
7mm+: 8kgs (I sink fast, so likely overweighted)
5mm: 4-6kgs.
Rash-3mm: 2-3kgs.

Its my first time trying it out so its a learning journey too.

Thanks for the link, I'll take a look.
Re the 8kgs, fair enough if that's for 7mm - I thought you still meant the 3mm, given that the (very rough) rule of thumb is 0.9kg bouyancy per mm (and your screenshot has +1.8kg for the wetsuit). Still seems a little on the heavy side so worth experimenting...

Re the wing, you'll be fine with the conventional 11 to 13 kg sizes, really no need for any more unless you're diving doubles. Give it a try, and I'd be surprised if (once rig is balanced) if you ever inflate it more than 1/2 full when subsurface

It's a tough one! Since it would be sinking about 600 usd into trying something out. On hindsight im sure the cost would be minimal in comparison to the other bits but still.

I agree that the math leans into the Zeos 28 being quite right buoyancy wise, and it might be nice not having to flap around with a large wing.

I assumed the requirement was for warm water diving. A 7mm wetsuit certainly isn’t for tropical waters, maybe more for temperate waters (South Africa? Galapagos?). If diving colder waters with 7mm and lots of lead then the Zen with 19kg lift may be more appropriate.

On the other hand I’ve never worn (since the lockdown) more than a Scubapro 0.5mm full wetsuit or a 1.5mm shorty in the waters of the southern Indian Ocean to the east Andaman sea and extending into the Indo-China-Pacific waters of the Philippines (ok Nusa Penida required a rental 5mm)…

Hence I came to the belated conclusion after the purchase that I never needed a Zen in the first place and I could have settled for a Zeos had I been wiser before the purchase.
