Recently took my first dives with a BP/W setup, 3 dives over two outings. Eclipse 40, SS plate and heavy STA, ACB 12 for eight pounds total, AL80. Although I was rather satisfied with my Black Diamond back inflate, I want to take my diving in a different direction, so the configuration change is part of that.

My first dive was far from the epiphany I have heard many other users describe. However, on saying that, that conditions were poor in the extreme and that could have colored the experience.

On land, the webbing hurt a bit (wearing 6.5mm wetsuit), though I did have a long walk to the entry. Once in the water, I was surprised that the unit was so vertically stable at the surface, much more so than my BC was. So far, so good. As a note, on the next set of dives and after some strap adjustment, the unit felt much more comfortable out of the water.

While descending, I did not that the rig felt much freer. The SS inflator is nice, feels solid, and mine was working. The dump in the back takes some getting used to. I had trouble finding the string reliably, though I am getting better at that. The dump works well, once activated.

I was a bit disappointed when I discovered that my trim was off. I was foot heavy at the beginning of the dive, but then foot light one the tank got below 800. This was discouraging. On the subsequent dives, I was able to drop 2 pounds, so now only 3 on each side in the ACB12, and next time I will try to drop another 2, where I suspect the limit would lie with this suit, total 16 pounds (including plate and STA).

Now, I have to experiment with trim weights to suss out my balance. I tired moving the tank up a bit, which seemed to help, but only a little.

Regarding the 7’ long hose, I was pleasantly surprised it really did not feel in the way at all. I like the idea of the necklace backup.

One other difficulty I had was with the little SS double ender clips. I thought I was a relatively coordinated person, but I felt like a fumbling fool trying to clip them on and off, especially for the SPG on the left hip. Felt like I was trying to unsuccessfully learn the guitar again. I had a look at the interesting OMS design for these clips that look much easier to clip on and off, but I will wait to see if I get used to these…

After care of the equipment is much easier for me. Mostly metal, and not so much fabric to rinse and let dry. The webbing and wing were dry inside a day. My old BC used to take days to dry, and boy was it heavy when wet! New unit also packs up a lot nicer for travel (I bring my gear by motorcycle in summer).

Overally, becoming more satisfied...trusting that the trim will be sorted out, though it remains a real disappointment at the moment.

It took me about 5 dives to start feeling comfortable in a back plate and now about 40 dive later it disappears when I am in the water. Don't know if you are looking for any advice but I would stay away from trim weight and try to just let you body adjust your trim. Once you learn to do this you can even add something to your rig like a bail out bottle in a staged config and learn to naturally compensate for the shift in trim. Like everything else, practice, practice, practice.

Great to hear your positive experience. I was actually thinking the same way...keep diving and see how if trim gets itself figured out.

Interesting comments.

For those who don't know Jagfish, he's pretty muscular. I'm surprised to hear his comments that the webbing hurt, especially with a 6.5 mil suit.

At first most people think that "bare" webbing hurts, but then they realize how streamlined it is and that they don't need padding because the harness and plate just "disappear" because of the way it fits. You don't need the padding normally used to compensate for bad design.

For the rear dump, the trick is to run your hand down the wing, finding the dump first then find the string with two fingers. Actually in maybe a hundred dives, I have only used the rear dump a few times.

What OMS clips are you talking about?

I think your trim problems will be solved when using 10 or 12 liter steel tanks instead of the Al 80s.

Cheers,
 
No doubt...
Many of these issues will fade away with use (pull dump and SS clips).

I hear you on the tanks...I think it would be best to get it all figured out with AL80s since that is what most places I go use (especially overseas).

As for the clips, they are on this page mid level on teh left side...called Stainless Steel Butterfly Swivel Bolt Snap:

They look really easy to clip and unclip.

Thanks for the support...

Muscular...maybe, but a wuss at heart.

I almost called ya a wuss, but then again, sometimes I dive Team Stroke.

Hey, ever hear of suicide clips?

You know what they say, Do It Right or DDIAL (don't do it at all).

Just my 2 cents here on these clips. I thought cool - these things are great. I can do this with gloves on. I bought a whole bunch of them. Then I read about them being suicide clips, so I thought I would do a bit of a test. Here is what I found out: These clips while making it far easier to hit your d-ring also make it very easy to clip off to other things. I tied off a bit of cave line and was shocked at how easy it was for the clip to attach. I then tried to do it with the recommended clip. These didn't do the the auto catch. I then took 20 # mono filiment fishing line - same result. Conclusion for me: I don't want clips that will attach to things that they shouldn't. I took back all the unused clips and traded them in for more appropriate ones. It may take a bit of time, but you will get used to them.
BTW- One thing I also did was to use a stage bottle clip (larger than normal) and attach it to my spg since that is the one I most frequently use. I feel very comfortable with it now. I may even change it back for a smaller size.
