Looking for an Engineer in USA

[JVanste]

I think a draeger gag strap with a comfobite or moldable bite piece will get you quite close. From your site it kinda sounds like you are trying to make a full face with low volume and isolated eye pocket. Would be interested to see it.

I do think it would be more important to have an experienced person properly trim you out. I don't know a single human that is naturally trimmed and properly weighted. Probably 90% of divers aren't either. I am constantly working on mine and sometimes I changed something and it sucks again.

Getting the right amount of lead, or in rarer cases foam, adjusted and placed properly could make the world of difference in someone unable to move different limbs.

The positive pressure with full face mask would probably be the safest option, but scuba is full of risks. Choose yours wisely.

I R engineer! Not sure how much help I can be.

You are absolutely correct! I'm trying to create a full face mask with low volume and isolated eye pocket. I want people with disabilities including me to be able to swim around underwater without the need for extra equipment.

Isolated eye pocket??
I would strongly suggest against it for any sort of depth but surface.

Here's a picture of me scuba diving in my pool.

As you can see from the picture, the full face scuba mask keeps me upright. I need extra equipment to put myself in a good swimming position.

Nope, your lungs are keeping you upright.
When floating on my back just in my swim shorts, I have to put my arms above behind my head as far as I can or I will go vertical. Same for face down. Legs will go down.
Your legs are just bones and muscles, they are higher density.
If you can, put your arms in front of you as far as you can. It's all about leverage, your lungs being pivot point.

Either way, I want something that's low volume.

You are also lacking the counter balancing properties of a scuba tank as you are on SSA. We also use trim weights. (I am very leg heavy)

Even hull cleaners using SSA use weights to sink and balance themselves out.

No, none of us have the physical challenges you have, but we do know SCUBA quite well...

Trim is a very important concept.

Then no FFM, and perhaps a gag strap as mentioned upthread?

I'd still hope @DiveHeart can weigh (pun intended) in...

That's why I'm working on developing a FFM

That's OK, but you do not want isolated eye pocket

A proper leaded necklace is all you need for bringing your head down. Free divers use them routinely.
See here:

Then, if you do not like your large FF mask, here is a low volume one, called the IST M37 Pegasus and found on Amazon:
