Our go-to OTS Guardian Full Face Mask in Black/Black—a rugged full face scuba mask trusted by Public Safety Dive Teams (PSD), dive professionals, and recreational divers. Stay warmer and drier with a secure double face seal, enjoy a fog-free visor design, and add underwater communications easily with the built-in comms port (including OTS Buddy Phone).

If you’re looking for a proven full face scuba mask that works across training, operations, and everyday diving, the OTS Guardian Full Face Mask has been our go-to mask for years. It performs exceptionally well for public safety diving, but it’s also a great choice for recreational divers and dive professionals who want a more comfortable, stable platform than a traditional mask + regulator setup.

Warm, dry, and comfortable for most divers

One of the biggest benefits of the Guardian is keeping your face warm and dry, especially in cold water, long duration dives, or high-stress conditions. The Guardian’s one-piece silicone skirt and double face seal help it fit a wide range of facial shapes and sizes, making it a strong “fits most divers” option for teams and individuals.

Built for harsh conditions (PSD, military, and professional use)

The Guardian Full Face Mask was designed by an ex-Navy Diver and built for tough environments—from military and public safety applications to demanding recreational diving. It’s a durable, mission-ready option that holds up when conditions are less than perfect.

Communications made simple (Buddy Phone + hardwire options)

OTS communications setups can feel confusing—hardwire vs wireless, mic/earphone options, surface stations, connectors, and integration details. That’s exactly why we help teams with this every day. We keep demo OTS communications gear available and we’re happy to walk your team through a clean, correct setup.

This mask is communications-ready with an integrated communications port, and yes—we can sell and support OTS Buddy Phone for underwater comms, along with other OTS communication solutions.

Clear view without the usual fog headache

The Guardian’s fog-free visor design means you don’t have to rely on a defogging agent the way you do with many standard masks—especially helpful for training days, repeated entries, and team use.
