Spectrum Vs. Guardian

OTS Spectrum Full Face Mask

$479

The Spectrum Full Face Mask provides a simple method to adapt your own regulator to the mask by eliminating the bite down mouthpiece and tying your own reg in with the rest of the FFM.

Specifications:

  • Lightweight design and easy to travel with
  • The Spectrum FFM allows you to use most modern standard 2nd stage regulators with easy installation and removal
  • Equalization is a breeze with the Spectrum’s traditional “pinch-your-nose” method
  • A double face seal and slightly smaller oral nasal cavity to fit most faces
  • Includes a communications port for easy installation of a Buddy Phone or ear/microphone assembly to connect an OTS Diver Communications Unit such as the PowerCom/MilCom series Diver Units (this point also needs to be updated on the Guardian FFM side – it currently says “such as the Aquacom SSB-2010)
  • Many additional accessories to choose from to allow a user to build it like they want it
