Hi Toddville 393,
Any decent / high performing 1st stage will work with the Guardian. For best performance, it is recommended that your 1st stage is set to an IP of 135psi.
Go-Pros are easy to mount with the Guardian (we have mounting brackets) and the video comes out great, depending on if you are whipping your head around underwater or not. I have seen some video that will make you a little nauseous.
Here is a video from a dive done on opening night of lobster season with a GoPro. What we've found is that attaching one of the two earphones (right earphone) from an ear/mic assembly, typically used with our transceiver units mounted to your tank strap, such as our SSB 2010, to the back of the underwater housing of the GoPro with a small amount of Dual Lock, which you can buy at any hardware store for cheap works great!
All the audio from the video is coming directly from one earphone to the back of the housing :

If you have any questions regarding the masks or any of our communications, give me a shout and I'd be glad to answer them for you.
Happy diving! I'd be interested in hearing how your experience goes with the mask at your local dive shop!

I enjoy my Guardian FFM. I do the bulk of my dives in quarries in Indiana, Illinois and Kentucky (read: cold water) and am not terribly cold tolerant. When my dive buddies wound up with one and raved about its benefits in cold water, I knew I had to experience it. I bought one last year and haven't looked back. I also like the wider field of view, lack of fogging issues, GoPro mounting options and of course, the warmer face.
I also have the BuddyPhone communications hardware, however the only place I've used it is in the pool. I found that it was causing a small leak on that side of my mask (possibly pulling down on the strap) and the bubbles became annoying. I hope to spend some time in the pool this winter perfecting it. I think with enough people around me having it, there are some situations where it would be useful. I don't think I will dive with the BuddyPhone all the time, however, since I do enjoy the silence when underwater. I wonder if the Aquacom unit and the separate transceiver would be less susceptible to causing leaks/annoying bubbles since the transciever is mounted off-mask?
Triker,
I'd be happy to direct you to a more expensive unit with an earphone assembly, but this sounds like an improper adjustment of the straps. When you seal the mask, be sure that it is sealed completely on either the skin of of your face -- or on top of a thin latex hood. If you are trying to seal on top of a thick neoprene hood, the mask can leak.
What I've found with the buddy phone is when you seat the mask on your face, try tightening the left side straps first, starting with the bottom. Then go back to bottom right, then right middle, then lastly, the top. This will force the strap harness to seat correctly on the back of your head and it pulls the weight from the buddy phone up to where it needs to be. The strap OTS logo should be seated just above the "knowledge knot" on the back of your head and all straps should be snugged up, but not cranked on your face.
One common problem we run into it that users of the mask tighten the top strap first, which can cause jaw fatigue over time, especially if you are using communications and cause discomfort.
Sometimes I wish I could I could take 10 minutes with divers face to face and help alleviate small issues like this, but unfortunately teleporters haven't been introduced yet.
Or if you'd like I can still direct you to the nearest dive shop
Hope this helps! If you have any more questions, please let me know!
