Beautiful Poseidon BeSea - anyone have this BC???

[Matsya]

Well... it CAN decrease your total amount of required weight as a BP/wing has little to no inherent positive buoyancy like some standard BCs. Often, one can remove 3 to 5 pounds from their total by ditching the BC and going to a plate. Also, and maybe more importantly, the total required weight can be REDISTRIBUTED to help achieve an EFFORTLESS horizontal trim. A great example of this is when diving cold water in appropriate exposure protection when weight requirements zoom. Instead of putting all of that weight TOWARDS the hips it can be more evenly distributed.

What am I doing... you guys know all this!

I really don't want to convert this into a BP/Wings vs Jacket but I guess that is where this is headed.
I have never done cold water diving so am not competent to comment on that. To be honest I cannot say I have done any amount of ANY DIVING at all !!! But I use a WI jacket. The weight is distribute in the weight pockets and the trim pockets. I use a total of 8 pounds. I like to think that I have achieved very good trim (I really don't understand what "effortless" means but I can maintain a very good horizontal position with negligible or at times even no finning). I don't know about the reduced positive buoyancy of a BP/Wings but I guess that is a factor of the way a particular brand of jacket is made (as you yourself have said Stephen Ash - you used the words "some standard BCs") and not an inherent disadvantage of the generic jacket design itself.

Perception is reality and ignorance is bliss.

Truer words have been spoken but these are right up there.

We don't know what we don't know, do we?

So... back to the subject of this thread. Geogeous BC is the BeSea. All the rest pale by comparision. Oh, and BC's are better than BP/W's. Humm...

Now now, coming from you these words gain a new...ummm....dimension.

your blackplate is still attached to a webbed harness, and while you are supporting some of the weight on your hips, your web harness was not designed to do such. I am sure much of the weih is still on your shoulders and back. Now I could be wrong, as I have not used a backplae and webbing. However, on my BESea I can undo the shoulder straps and still support the tank. The waist belt is design is based on a backpack concept.

I beleive your harness and backplate probably provide a very secure feeling, which translate in to the comfort you feel. I am not sure if the design of the back plate and webbing can provide the same level of support as the Posedion BeSea does with its harnessn design.

At the end of the day, to each their own. I feel one should dive with what they are most comfortable in.

Hello Everyone,
This is my first time responding on an issue, so please excuse any mistakes. For many years I have dove with both an OMS SS backplate system as well as a Dive Rite Trans Pac. Both are excelllent systems which have proven themselves in both the Cave and Tech communities. That being said, I have recently tried out the Poseidon BeSea in both a pool, and a freshwater lake. The BeSea does seem to give much better support while on land than either the OMS or Dive Rite. I have a very bad back due to working in the field of Emergency Medical Services for close to 30 years, as well as being in a bad car accident. As a result, I have spinal stenosis as well as 3 herniated discs in the lumbar 2-3 region. This simply translates to my not being able to take much pressure or load bearing on my lower back. I honestly thought I would never be able to dive with doubles again, or for that matter, even a single steel because of the pain it caused. The BeSea does indeed remove the weight from the upper torso and transfer it directly to the hips, relieving the lower back. I tried the BeSea with my twin LP 95's with no problems. I could walk around with little to no pain, something I could not do with either the OMS or Dive Rite. In the water, the Be Sea worked fine for me, and I am definately going to get one. This is my personal experience, so of course I cannot say that the BeSea is right for everyone. I also am anxious to see what the second generation BeSea will be like. Hopefully less buoyancy, and maybe attatched to the next generation Cis Lunar rebreather.
At least one can wish.
Happy Diving,
Bear

Could the inherent bouyancy of the posedion bc be because its made in sweden and they use dry suits which need more weight. I'd like to try one if they came out with a more neutral warm water one. I love my Zeagle but this BC looks good.

I guess they look pretty nice, but I don't know how excited I'd be about having to wear all the extra lead to sink that thing. It's got to be about 10 pounds positively buoyant with all that padding. :11doh:

The besea 100 is nice I have one but... if you are not a tech diver (I am not) the 100pd bladder inflates unevenly and the design is such that the hoses of a smaller tank (MY 80) will cut off the bladder at the top of the BC. also the inflator hose must be held completely vertical on decent which means you have to remove it from the strap and reattch after you decend. other than that it requires no "extra lead" than normal and drives like a cadi. hope this helps

Hi Bambi,
If you're diving the BeSea 100lb bladder with an AL 80, you definately have a case of buoyancy overkill. The 100 lb bladders of all makes are designed for use with heavy doubles, and can actually be a hazard when used with lightweight singles such as an AL 80. Not knowing your diving experience and kit setup (ie wetsuit/drysuit, weight required etc) it's hard to make recomendations. However, I'm willing to bet that if you used the 50 lb bladder, you would be alot happier, and your buoyancy will be much easier to control. Even with my current OMS setup, if I'm using a single tank, I remove my 100 lb twin bladder, and replace it with a single bladder 50, even with a single steel tank for the same reasons - better buoyancy control and streamlining. Try it and see for yourself.
Take care,
Bear

Hi Bear, thanks for the tip. I have a 50lb bladder on order. I dive PST steel tanks but my hope was to grow into the BC and do some technical diving... still might, but for now just want to recreational dive.

The chart is a great brush-up on physics terms for kg/lb. Nice detective work.

All you need to do now is run out and get one of these things. X

Ok here it, this 5.3 lb force…

Using newton's first law

, where F - lbs force, m - mass (lbs), a = acceleration or g unit so to calculate lb equivalent:

m = F/a

5.3/g-unit = 5.3/ 32.1740486 foot/square second = 0.1647lbs…

Practically neutrally buoyant. Could someone correct me if I am wrong here, cuz the G-unit in water maybe different...
