I find when I take a passenger, even my daughter Roman who is light as a feather, I am always quite over weight. That is no problem at all in a Gamma size sub because the vertical thrusters have enough jam to stop the sub hitting bottom. A trim tank would be good to keep you closer to ideal weight, or have lots of small weights to take out. I foolishly made two rather heavy lead weights. </span></div><div dir="ltr"><span>Are you running your O2 through a ss nipple, is that okay, I am planning to do that for external O2.
