howdy,
I too have the ocean reef ffm. I don't like it much, for 2 reasons.
1. the internal volume is large, which makes the mask too buoyant.
2. I can't get the reg to crack where I want. There's very little adjustment. I get tired inhaling.
I also used a Cressi-Sub ffm, the style that was advertized with the Viking Unisuit. You can install any reg in it. Didn't have comm support, but good for dirty water.
The best was the Kirby Morgan band mask However, I dove that one surface supplied. The gas block was just for a bailout bottle. All the blending was done topside. I'm not sure you can swim with it. I was standing.
I just ordered two AGA masks to try them out.
I wold like to know why Uncle Pug sold his!
The SRT guys seem to love them.
As to why I like ffms, I'm spoiled with having a comm unit, where I can talk to the surface support crew, and other divers. I personally believe that so many accidents would have been easily prevented if everyone was using comms. I've asked topside for tools and been able to shae intresting sights with my buddy.
Also, I am quite loquacious (as you can see) and get lonley and bored if I stay quiet too long.
happy days,
Warren
