Ocean Technology Systems

OTS is a great company with superior service. We purchased 2 Guardian Full Face Masks with Buddy Phone’s and absolutely love them. My girlfriend sometimes has anxiety when she dives and these have eliminated that. Being able to communicate has made all the difference. Not to mention never having to put anti-​fog on a mask again. Oh yeah did I mention you don’t have to ever clear again, it is worth it for that alone.
Dennis in the service department is amazing and has taken great care of us. Mike gave us great training and Renee was extremely helpful on the initial purchase as well as her after sale service.
If you are thinking about a full face system OTS is the best and most reliable. For the exception of replacing batteries the masks have worked flawlessly.

We purchased 9 of the Guardian Full Face Masks (FFM) and 9 of the Buddy Phone systems in 2010 for our joint police/​fire dive team.
Prior to the OTS masks, our team had been using the Ocean Reef masks, which advertise themselves as FFM with comm, but they are not. I’m afraid we were the victim of predatory sales: The Ocean Reef masks were a complete waste of time and money (poor fit, leaks, horrible comm, and exposed circuits that actually burned your lip like licking a 9V battery). So, we liquidated the Ocean Reefs and found OTS based on a recommendation from John Chatterton himself. John Hott at OTS couldn’t have been better: Expert advice, good sense of humor, understood our needs, and even hosted us on the OTS boat for day of diving at Catalina to try the masks ourselves.
Equipment is very well made, and while the gear is expensive (all scuba is expensive though), you are definitely getting your money’s worth. Customer service is OUTSTANDING. So, if you have any hesitation about spending the money on a FFM with comm, you can relax because you’ll be in good hands post-​purchase. High quality hardware with great support.
After nearly two years of in-​service use in altitude, cold water (including ice), and usually zero visibility, these masks have met or exceeded every expectation for performance and comfort. Worth every penny.
HIGHLY RECOMMENDED if you are in the market for FFM with or without comm.
