Why dive an IDM

After you read the above, you might also want to check out:
  • Apertometer: competitor comparison with our field of view.
  • Visor treating: the importance of having scratch resistance inside and outside means that, while an outside scratch on underwater equipment is a minor problem (the water will fill the scratch and you won't be able to tell it's there), an inner scratch will be very visible, also once underwater. Thus, OCEAN REEF IDMs, the only Full Face Masks with coating on the market, highly reduce the possibility you will ruin and need to swap your visor.

sizing chart for IDMs web

The Neptune Space is available in two sizes, Small/Medium and Medium/Large.The sizing and measuring system were designed in accordance with the official measuring procedure used in the Los Alamos Scientific Laboratory Charts at the SBCCOM Mask Fit Facility-Aberdeen Proving Ground (Maryland, USA). Before purchasing a mask, the customer may use the calliper to take two simple face measurements. Using the Full Face Mask Size Recommendation Chart, he or she can evaluate the size category into which the measurements fall. There are three different size categories on the chart: Small/Medium, Both, & Medium/Large. If the measurements fall within the both category, then the diver should technically be able to wear either full face mask (M/L or S/M), and in that case should try on a mask to select the best fit. Please note that the chart boundaries fade. The fading areas represent less common face measurements. It is very likely that a mask will still fit comfortably even if measurements are located in these fading areas.If needed, OCEAN REEF has available to purchase a measuring kit.
Our older NACS was built with the possibility of breaking (for engagement reasons) in mind. Our customers (not everyone) didn't like the fact that it could break - they preferred something sturdier and more reliable. We created the Extender to solve this problem too. The concept is the same as the old NACS, but it's now a solid piece with the frame. this distributes the weight perfectly along the mask AND is comfortably located and rigid so that it does not flap on your ear when moving.
These earphone supports serve multiple purposes. First of all you have 2 of these. You can mount either one, or both together. When mounting both, you will have to renounce to the new NACS. These are the natural fittings for the earphones (MHA-2) of the GSM G-Power SL communication unit, once complete, this systems let's you enjoy a double speaker system, with volume control and extra range. Either having or not the GSM G-Power SL unit, the supports, once the plug is inserted, can serve as sport camera supports (such as the GoPro camera) - the shape is that of the sticker for this popular camera, and you can then figure out a 90° angle arm. Or, you can just drill holes in the plug, and mount whatever you want to them. The plugs rotate 30° vertically, which means, anything you attach to them will be able to do the same! for example - a light!
The frame has a flat, trapezoid shape, specifically made for sport camera stickers, or to drill holes and fix lights to it.

The beauty of diving IDMs is that you have a lot more than a mask and regulator – you have the space and ability to add (integrate) accessories to your breathing and visual apparatus. We have a whole set of accessories designed to add features to your mask that will broaden your options while diving.
