well they cant be that bad if the UDT , EDU and SEAL teams are using them
Gotta remember that the EDU/UDT etc doenst necessarily select a piece of diving equipment solely on its performance needs.
There are many other factors including. allows divers to wear while inside the SDV. Is cheap enough for seals to ditch when they hit the beach on certain missions. Easy to stow away in their alice packs, its light enough to carry on long ground missions etc.
There are many factors in its selection. But, unlike weaponry its mostly based on compactness and cost.
For example I bought an official seal issued diving mask 3yrs ago. I believe it was an oceanways teardrop style mask. The one you mostly see seals wear in pictures etc.
Well it cost me $12 at a Navy PX. The same mask i saw for sale at a local dive shop for $19.
Its probably as good quality as a mask you buy in kmart. But, the Navy didnt buy them for ultra performance, they bought it because it was cheap and thus desposible.
Now i will admit one thing though. This $12 mask is still my primary dive mask. While i have a $70 dive mask that is far better in quality which i use as a backup mask.
Why? because it is the lowest profile mask i have ever seen. Its comfortable and the teardrop design is awesome.
Teardrop design:
The top portion is like those old style round faceplate masks while the bottom is teardropped shaped much like bomber sunglasses.
