<div dir="ltr">Yeh, I forgot to mention that the viewports are also designed to seal from the inside so that would have to be changed. A 2m OD is a pretty large deco system if that is what it is. Couple things to think about, being a double lock system, there is the weight of the extra dish and hatch inside plus having such a large OD, you would need a heck of a lot of ballast to counter that positive bouyancy. Also need to have someone on the list re calc the numbers to come up with a proper frame size and distance apart.<div><br></div><div>Good luck</div><div><br></div><div>Rick</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Mar 26, 2015 at 7:31 AM, James Frankland via Personal_Submersibles <span dir="ltr"><<a href="mailto:personal_submersibles@psubs.org" target="_blank">personal_submersibles@psubs.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div>I've been in this one (as a test, not for treatment).

You would also need to add internal or external frames and if you chose to go internal, you would have to install them in two or more pieces as the chambers have the dished ends on them and then a smallish entry hatch to contend with plus any system that I have been in, the doors are designed to seal from interanl pressure. Just some things to ponder.</div><div><br></div><div>Rick</div></div><div class="gmail_extra"><br><div class="gmail_quote"><div><div>On Thu, Mar 26, 2015 at 1:52 AM, James Frankland via Personal_Submersibles <span dir="ltr"><<a href="mailto:personal_submersibles@psubs.org" target="_blank">personal_submersibles@psubs.org</a>></span> wrote:<br></div></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;padding-left:1ex;border-left-color:rgb(204,204,204);border-left-width:1px;border-left-style:solid"><div><div><div dir="ltr"><div>Hi All,</div><div> </div><div>I am thinking about my next sub.
