Cressi Sub Jac Light BC Review

When I first started to dive it was a case of grab whatever fitted from the rack in the school and to be honest at first I was not very impressed with the Scubapro Glide BCs (Buoyancy Control Device) I was using during my training. They were old and well worn school jackets and I found them restrictive and uncomfortable to learn in.

I had so many other things on my mind (like remembering to breathe) that I was becoming a little dis-illusioned by a BC that inflated around my sides making me feel squashed all the time. So my instructor started lending me his old BC after I had done 5 or 6 dives after my Open Water course finished and straight away I felt much more comfortable and the Cressi sub Jac Light BC became my choice every-time I went into the equipment store.

Cressi Sub Jac Light BC

A wing style BC isn’t for everyone and as a complete beginner to diving I would never suggest something that makes life more complicated, especially the BC and Regs, but that is exactly why the Cressi Sub Jac Light is some thing I feel a beginner would benefit greatly from. Because it is a travel BC it is limited in the things it has, such as pockets and D-rings and as a beginner I found I didn’t need anything more than to clip my gauges and octopus to.

The shoulder straps are shaped nicely and seemed to fit my physique well, with a little adjustment it was like a clamp holding the BC to my upper body and the elasticated chest strap made for a tight fit allowing me to relax even more feeling secure in the knowledge it wouldn’t come off. I did notice straight away it had space for 2 tank straps, but as a beginner wasn’t aware how important that could be as the single strap always felt secure on the tank and it was easy to put enough pressure to take the slack out of the band and secure the tank properly, hearing the thunk as the plastic clamp was flipped into position always made me feel re-assured it wouldn’t let the tank slip.

Being comfortable in the water is something every diver finds important, as it was for me, and as my first BC that my instructor and I came to a deal on for me to have it became my baby, it fits me so well I will be sorry for the inevitable day I have to change it and even though other divers warned me of the problems of being pushed forward when on the surface with a wing, found I adapted to it very quickly and wasn’t in any way encumbered by the BC. However at the surface this BC does rise up slightly pulling the cummerbund under my lower rib cage and this is the only real fault I have found but a simple crotch strap fitted between the back plate and the cummerbund would fix this.

It has an integrated weight system that clicked into place securely but allowed the weight pockets to release so easily with a gentle pull, easing another worry off my mind. It also has 3 dump valves, 1 on the lower right rear, right shoulder and on the inflator hose, they are easy to pull with just enough cord so it doesn’t tangle on anything else when in the water in case of an unexpected rise to the surface, and I had a few of those to begin with so they became well used. I was also shown the technique of rolling over to allow the air to fill into different parts of the bladder making it even easier when I needed to use the pull cords.

When I started scuba diving I had no gadgets so didn’t even think about D-rings or clips but for a travel BC the Cressi Sub Jac Light comes with 4 stainless steel D-rings and they are ideally located 1 on each front strap at chest height and 1 under each weight pocket within easy reach to unclip or clip things as needed. It also has a small pocket on the right side under the weight pocket, a little fiddly to get out but just the right size for 1 or 2 items, like slates, line cutter, spare mask (just squeezes in). I can see why they have kept the weight down by not putting too much on it but personally another pocket on the other side would have been handy at not much extra weight and as I am not rich (like most of us in the real world) can’t afford to replace the BC easily so have come up with something that I will post about at a later date.

As a beginner the Cressi Sub Jac Light BC in the wing style would be one I recommend to anyone that is thinking about starting to dive, purely because of its simplicity in design and rugged material while remaining light weight for transporting, it is a shame that Cressi have brought out a new model because finding one of these will be a search on the second hand market but that will bring kit costs down a lot, make sure if you do buy one to get it serviced by a good agent.
