I use a DAAM and like to swim on my back if I have to surface swim any distance on shore dives. I find it easier to stay on course, be more aware of surfers, swimmers and other surface objects, and I can kick more efficiently on my back.

DAAMs free flow when you're on your back and I have not found any commercially made mouth plugs that are wide enough to fit the double hose mouthpiece. I resort to holding my thumb over the mouthpiece.

I have heard that divers used a wooden plug in the past. Before I start whittling one on my own, does anyone have any pictures, specs or diagrams of what those old plugs looked like?
 
At one time Vintage Double Hose sold a rubber plug. They are currently shut down however. I have one somewhere in my pile of SCUBA stuff. IF (and it's a big IF) I can find it, I will post dimensions.
 
In olden times we mostly just shut the valve off until the surface swim was done with. But people did use plugs. I would tie mine on a string to the hose near the mouthpiece, still do if not using the VDH DSV. In recent times several sources have produced various rubber plugs and referred to them as a PMDSV (poor man's dive/surface valve).

I would look at investing in the DSV from VDH. Also gives you the ability to swap mouthpieces to whatever you think is most comfortable. It's the bomb dot com @Luis H did a brilliant job with it
 
I don't believe Bryan will ever make these plugs again. I designed this back in 2009, but this drawing is from 2012.

These plugs worked great with the US Divers curved mouthpiece (original or reproduction). It doesn't work with other mouthpieces, they are all different.

Notice the curve mouthpiece has sharp inside corners. You don't want to round the edges, they just don't need to super sharp either (or have burrs). The rubber plug that Bryan used to sell was probably the best, but it can be made of other materials.

If you are going to carve one out of wood, I recommend something like Teak. It will last longer and you can get a long lasting finish by just sanding it smooth.

Note: this is just a plug... you don't really need to keet the dimensions down to three decimal places. It is just a tapered plug, not a Swiss watch. Sorry about the unnecessary implied precision. I just didn't paid attention to my dimensional settings in AutoCad when I did this drawing. That is bad... :oops:

Hey!, I believe that "Poor man's DSV" was my the name I came up with for my plug... :wink:

Indeed you did Luis. That would be my recollection as well. :) And a fitting one. And Luis also designed the real DH DSV that VDH sold as well! The plugs had existed off and on but there had never been anything quite like the VDH double hose DSV.

Thanks.

Yes, I prefer using my DSV now, but the curved mouthpiece used to be my favorite DH mouthpiece.

The plug was a very simple solution at the time. It really worked amazingly well for what it was.

I have not used the curved mouthpiece in years, but I should, just for old times sake.

Luis, with your permission, I can whip up an STL file for this and print some in TPU... I need one myself, and could send some to those in need. Your design though, so I don't want to step on your toes (so to speak).

Yeah, using a plug itself was nothing particularly original, but after I did mine, I have only seen home-made ones carved out of wood and they all seem to have rounded edges.

Having a relatively sharp edge can be difficult with most woods. That is why I am recommending Teak. But I will admit that I am not a wood carving expert... or any kind of expert.
