    Halcyon manifold with no burst disks

    You would need a wrench to tighten down a metric thread manifold onto a 3/4" thread tank, it would not spin on by hand, and I think you would have some idea that you were screwing things up when you were forcing things together. If it threaded easily, then the threads are Ok, but I still would...

    Halcyon Manifold 3/4 NPSM ITS OK(NO BURST DISCS

    If there will be any problems with shops filling the tanks with a manifold intended for overseas use. I thought it was a legal requirement in the US (DOT regs) that all valves be equiped with burst discs.

    Halcyon ACB vs. OMS No-Sag pockets

    Works good. Comfortable, can be slid up or down on the waist to fine tune trim, more streamlined than the ACB's. That's what I have. Oh, and since it is stretchy, it is depth compensating too.

    Help Me!!!

    SD03, I see you live in the Seattle area, so do I. where did you buy your reg. from? If I were you, I would have your regulator serviced by a reputable dive shop before you use it, there are a couple that are pretty close to you. Once it is tuned up, it should give you years of service. But...

    Wetsuit donning question

    you've got a wetsuit that will keep you honest: Don't gain any weight!! Baby powder is messy when wet. What are you wearing under your wetsuit? It can be a wrestle to get into a wetsuit that fits snug. I would evaluate how "snug" your new suit is. If it's is too tight, you might want to...

    About to purchase a BP/wing setup

    I use the 1/2" fittings/hoses on my Apeks 200 and the hose is not any stiffer that the 3/8" size, in fact, it is the same diameter. The difference is in the size of the opening on the fitting that screws into the first stage, and the oversized port on the first stage, not the hose itself. 5th D...

    Halcyon - rust problem

    You don't need the steel grommet on the webbing, in fact, if you remove it, the tank will sit flatter against the backplate. With the grommet from the webbing, plus the grommet on the Pioneer wing, it creates a high spot under the top bolt that is thicker than the built in STA's, causing the...
