Pull dumps on their inflator hoses? Do they have valves at the bottom for dumping while upside-down?
I read something about Halycon supplying a "bungee" for keeping the power inflator tied down to the shoulder strap... That sounds pretty homemade, doesn't it?
I've never dived with anything but a standard BC, so back inflates and backplates are completely new to me.
Also, is it possible to get a backplate setup with integrated weights? I guess what I'm really asking is if I can get the weights off of ME and onto the rig, and still have a system where it's easy to dump weight in an emergency.
This would be my first BC setup... Everything I've worn before's been borrowed or rented.
I'm also wondering if I'm unique here... Everyone seems to be swimming with so much weight! I'm 6'1" and started diving a month ago at 230 lbs or so... I'm now down around 218 or so. Having always worn about ten pounds, but now sporting a new 3/2 mil wetsuit, I thought I'd go and see how much more weight I'd need.
My sweetheart was doing some pool work for her certification, so I took the opportunity to climb in with full gear and see how my boyancy was, without a current or wave intervention.
In PADI we're instructed that with no air in your BC and a full breath of air, you should float at eye level with the surface of the water.
Imagine my surprise when I found that I took a whopping six pounds off! Now I'm swimming with about 4 pounds...
Okay, I've got some disclaimers here... Firstly, this is a 3/2 mil suit... Many people are diving with 5 or 7 mil... But still...
Also, this was POOL water... I'd be much more boyant in salt.
Lastly, while the feeling of "lightening up" was GREAT and made the experience sooo much better, I found that breathing now affected my boyancy more than ever. Also, I found out that I had a leaky inflator valve... After just a few minutes, I had to dump again to maintain boyancy. I can understand, too, that some people like more weight so that if they want to go fully negatively bouyant so that they STAY on the bottom, particularly useful in a stong current...
Still, I was floored to find that I was using just 4 lbs WITH a wetsuit. The BC was a standard jacket style, and other than a dive tool and a whistle and a min PCa dive light, I had no gear to speak of. I was diving with your standard run of the mill AL80. (Maybe I was using a steel 80?) Maintaining bouyancy was easy and a blast.
I can tell in freshwater with a current I might want to go up to five or as much as seven pounds, max. Heck, I might even want to stay at 4 pounds... The feeling was wonderful and natural, and with a wetsuit, you become more negatively bouyant as you sink, right?
I don't know what this would translate to in salt water... Somewhere between 10 and 15 pounds, I believe.
My point is this... I'm thinking about purchasing gear... Especially since I don't seem to need (or like) to swim with much weight, I'd like to go with weight integration. Seems like I'd get all the benefits without the disadvantages. And sometime in the next year or two I'd like to start with doubles. Does that mean I'd HAVE to go with a backplate at that time? If so, I might as well save myself the money and go with a BP now. But given the weight situation... Will a BP, even WITHOUT weights, be too heavy for me?
