Hi Ready4Launch,
The Spectrum FFM, as the Chairman is speaking about, does not have a plastic shield covering those nose pocket like the Guardian FFM (shown in my photo) or the Stealth FFM. The Spectrum has a soft silicone nose pocket where you can reach in and pinch your nose like traditional half masks.
To equalize in the Guardian / Stealth FFM with a poly carbonate visor, we have an equalizing block or "V-Block" that sits on a metal wire which can be customized to sit just below your nose. When you want to equalize, you simply push up and in on the regulator / mask to help seal the block against your nostrils to equalize. When this block is set up correctly, you should only need moderate force to equalize and it should be comfortable. To see what the blocks look like, please feel free to visit our link here :
Shop | Ocean Technology Systems We also have a variety of training videos on our website if you're interested in more info.
A few reasons recreational divers are using our FFMs is that they offer benefits over a traditional half mask like :
- Reduced jaw fatigue as you are not biting down on something. This has been big for disabled divers / veterans who are unable to bite down on something
- Reduced dry mouth as you can breathe through your nose
- They help keep salt water out of your eyes
- They allow for underwater communications if you'd like to go that route
- If using the Guardian / Stealth FFM, the mask self defogs. No need for defogger / spit into the mask. The Spectrum does require a defogging agent.
- Keeps face warm when diving in cold environments
If you have any other questions, please let me know!
Cheers.
