Newbie JJ diver advice

[bipolarbear]

Congrats on moving to the silent side.

Are you saying your going to do Mod 1 Helitrox (45m) soon and hope to knock off Mod 2 within 2 months of that? It seems ambitious to me. I don't know Will personally, but I know some very good divers that he has told to go away and come back when they had practiced more (i.e. a year)

I was also told recently, that MOD 1 now has a maximum deco time, so whilst Bikini isn't a heck of a lot deeper than a MOD 1 cert on average (say 50m) it clearly is a lot more deco.

Best wishes ... you'll need alot of ascent and stop work, belting up and down an ascent line very GUE Fundies esk, to practice bouancy and minimum loop volume.

Yes I think having taken a step back to reconsider this is probably too ambitious. I'll lock in my Mod 1 Helitrox and then dive as much as possible for the rest of the year. Then look at taking Mod 2 sometime in 2026 once I'm more comfortable on the unit.

Looks like Bikini will be an open circuit trip for me. That's a bit of a shame because I was hoping to avoid having to do those deep dives on air. I was in Truk last year where trimix is not available in sufficient quantities for open circuit and doing wreck penetration at 50m+ is just not my cup of tea anymore (and is, for me at least, frankly unsafe). Even without penetration, I would have really liked to have better recollection of some of the 60m+ wrecks I dived in Truk (IJN Oite being a good example).

Well its ambitious I didnt say you shouldnt have a crack.

You can certainly use the JJ for the workup dive the Prinz Eugen some livaboards are pretty easy going. There may even be a JJ instructor onboard.

1. JJ Sucks big time in warm weather wet diving. I use carbon backplate, aluminum cylinders and travel stand and deep6 Eddy fins to mitigate the issue. Like stated above, seahorse trim is kinda unavoidable.
2. I am coming from backmount doubles and stages background too, and at MOD1/Tec1 level that’s pretty straightforward. However it starts getting complicated at Normoxic and Hypoxic level pretty quick and that depends how do you want to carry bailout, if you want to stick with stages, be prepared to do lots juggling and carrying tanks on the leash. I sidemount my bailouts and that makes life much easier in few aspects.
3. Air travel with JJ is discouraging, specially if you have to fly economy. Level of discouragement depends on you, to me it was discouraging enough to buy second CCR for travel.

I hope it helps and welcome to the club.

Hi, which one did you buy to travel ?

Lastly, I note your point re air travel. I will often fly economy but I always have heaps of luggage allowance (80+ kg) due to status. Would you recommend just getting a pelican case for the JJ and, if so, which one?

Have a look at this thread. It's about my original JJ, but it's all still relevant
