Question 1

What if the mask fogs?

Accepted Answer

IDMs do not fog – no product treatment is needed thanks to the 1 way air circulation system achieved with the orinasal pocket. The orinasal pocket also keeps separated fresh air for inhalation from the CO2 exhaled.

Question 4

Can I wear glasses while diving?

Accepted Answer

The optical lens support is a dedicted frame, compatible with the scuba line, the ARIA mask and other snorkeling full face masks, which allows to use optical lenses (lenses not included) with the mask. Easy to place and remove, it gives you the ability to share the mask with anyone by just adding or removing the lenses.

Question 5

What if I’m in an out of air situation?

Accepted Answer

There are 2 ways, we recommend, depending on your configuration:
 • Without removing the mask: if you and your dive buddy are equipped with quick connection on the IDM regulator and on the octopus. Procedure: (diver A is going to share the air, diver B needs air). Diver A disconnects the lp hose from his octopus, diver B disconnects his lp hose from the IDM 2nd stage and Diver A connects the yellow lp hose to diver B’s 2nd stage
 • Removing the mask: if not equipped with quick connection, or for preference reason. Procedure: by using the quick release Diver B removes his mask and gets his buddy’s octopus in the mouth. We always suggest to keep a conventional spare mask in the BCD pocket. In the training section you can find helpful videos on how we recommend to perform these drills – we highly recommend to get training in a certified facility for added safety and to really get the best out of your equipment.

Question 6

How do I wear the mask? Donning/Doffing the IDM

Accepted Answer

Release all the 6 straps. Put the mask in place and then proceed with the correct tightening order:
 • (from top – forehead – to bottom, vertical) pull middle ones;
 • Make sure the strap is still in place, well centered behind your head, if necessary pull it down;
 • Tighten the bottom straps;
 • Top straps tightening. DO NOT OVER TIGHT.
Doffing procedure: grab the two quick releases (or the tabs) and pull them outward in front of you.

Question 9

Multi gas dive: Yes. Professional line masks come 40% Nitrox compatible. There is the option for a Space Extender 100 O2 compatible 100%.
