    I purchased your Mantis full face mask a couple of years ago and just loved the full face comfort, and the way that water was releasing with each breath through the bottom valve, but breathing through my nose was a little difficult, but could be done. I just receive your Spectrum and dove with it the first time this past weekend. I was blown away with the comfort, doning was quick and simple. Breathing through my nose was like I was not wearing a mask at all, just natural breathes and my air consumption was much lower. The ABV worked great at the surface, much easier to use than the one on my Mantis. The chin tab to release water works okay, but I had gotten use to the valve on my Mantis, so I had to remind myself to pull it when I was at the surface. If the Spectrum had the same release valve as the Mantis, it would be the perfect full face mask in my opinion. I am working towards my PADI Divemaster and I frequently help my instructor with Open Water Classes, so after our flooded mask skill, I always put on my full face, you would not believe how many comments and questions I get about it. There are dive schools from Texas, Colorado, New Mexico and Oklahoma at our open water location, so I am very proud to show it off. I wanted to let you know my thoughts on your Spectrum, keep up the good work.
    Thank You,
    Kelly F.

    I am a professional hull cleaner in the San Francisco Bay Area and have been using full face masks for work for over two decades. The OTS Spectrum is hands-down the best mask I’ve ever worn. It’s comfortable, dry and looks cool. Plus it seals perfectly on every hood with which I’ve used it. I love it.

    Just purchased the OTS spectrum also the ABV & even though I have only done a practice dive I have to say I’m very happy with it.this is my first ffm n I’m impressed with how comfy the mask is when it’s on ,it’s so nice to be able to either breathe through my nose or mouth it’s just a bit freaky .
    I’m not keen on cold water having done most of my diving out of the uk but now with the spectrum I am now looking forward to doing a lot more when our club starts up again I’m sure I will be asked loads of questions by members when they see it.

    I just pulled the trigger on this mask after I tried one in the pool. I like how comfortable this mask is and being able to breath out of my nose. I also have a guardian which is second to none in my opinion. I liked the guardian so much I had to try this option. This is a great back up for the guardian, and in the future, I can get a buddy phone for both so I can communicate with a dive buddy for a more enjoyable dive. OTS? Great job!!!
