With over 60 years of diving experience and having sold almost every Full Face Mask on the market, it was easy to see there was a need for something better. OTS put together a design team consisting of Mr. John Hott, Mr. Michael Pelissier, Mr. Charlie Van Tassel (outside consultant), and Mr. Jerry Peck.
Charlie was primarily tasked with regulator design although he proved invaluable in helping with the interface of a full face mask and 2nd stage regulator. John, Mike, and Jerry concentrated on the mask concept, features, and overall design.
A common problem with most full face mask on the market today, is the seal. The lack of a good seal causes the diver to use air quicker and can interfere with the diver’s ability to hear if using underwater communications. With that in mind, the Guardian was designed around a double seal. This along with many other great features (i.e. semi positive pressure, quick release 2nd stage, easy maintenance, etc.) is why you will find the Guardian is the best choice for your money when looking for a full face mask.
