The Double Seal was specifically designed to allow people with a small faces or a slim face, especially in the temple area, to seal better. Everyone has a little different face. As divers you all know how important being able to equalize is. Equalizing is a challenge for all full face masks one size does not fit all! In order to ensure everyone can equalize, we have put together an Equalizing Kit which comes with every Guardian full face mask. The kit consists of two bases. One is a standard size without any holes. It can be adjusted up or down to fit as necessary. The other base has two holes which allow for different size pads that can be added. In the event the standard base does not work for you, one of the pads and the other base should fit the bill. The Guardianoffers an easy to adjust buckle system. The strap is just the right thickness to allow for a comfortable fit no matter what depth you go to. As you go deeper, the strap will help take up the slack. When you go shall ow and everything readjusts, so will the strap keeping you snug in your Guardian full face mask. We have made the buckles out of a tough, robust compound which should give you years of use. However if a buckle does break, it will be easy to replace. There is definitely one thing you won't have to worry about and that is RUST. Rust is the number one cause of replacement when using metal buckles. The ABV-1 Ambient Breathing Valve allows the user to breathe ambient air at the surface, conserving your tank air. It is simple to use and its low profile keeps it out of the way. To use the device, while on the surface simply rotate the valve counterclockwise. The one way valve will open and allow air into the FFM. The one way valve located on the inside of the FFM ensures that your exhaled air does not go back out the valve. Your exhaled air is sent out through the second stage regulator ensuring you do not get a Co2 "building" in the FFM. The valve also is forced closed when diving. The over pressure in the FFM assures that. If you forget to close the valve before diving, the valve disc will help keep water out. The Guardian full face mask has a custom designed 2nd stage regulator that was specificallydesigned for a full face mask. We also realized what is involved with the maintenance of a full face mask and regulator. We designedthe 2nd stage with trouble free maintenance in mind - it is easily removed! This is important for cleaning and/or maintaining your full face mask.
The Buddy Phone¦ D2 is a digital, micro-miniature, ultrasonic transceiver allowing communication between two or more scuba divers or surface stations. Using "Digital Signal Processing" (DSP) techniques, the Buddy Phone produces uncompromising speech clarity. The Buddy Phone¦ D2 differs from our standard Buddy Phone in that it is digitally controlled and has some fantastic new features such as: a voice menu to guide you adjust your Volume, change from channel A to Channel B or put the Buddy Phone in a continuous voice transmission mode. Voice Menu: When you submerge with a D2 Buddy Phone, you will hear the voice system say "Buddy Phone ON, frequency A (B), channel one (four), volume High (Medium, Low)," depending on the prior dive's settings. Changing a setting is easy and can be done while underwater. Depress the Push-to-talk switch (PTT) three times quickly and hold the third depression until you hear "main menu - volume, channel, continuous transmit." When you hear the main menu selections, simply depress the PTT to select one of the choices. The unit will make the selection and go back to the receive mode. If you don't make a selection after the menu repeats twice, the D2 Buddy Phone goes out of the main selection menu and back to the receive mode (see operators manual for a more detail explanation)(note: continuous transmit mode allows the user to talk, hands free. This was requested by many movie makers and scientist who talk on camera often).

Comments about AGA OTS Guardian Full Face Mask Package and OTS Buddy Phone 2 Channels, Black:
i was recently using this for a six week commercial project and it definitely filled its niche. we required comms and that made this hat ideal. however, one thing i might mention on this is that this system eats batteries. i mean it goes through them like crazy. comms start to really suckin' when the batteries start dying but are really good when they're fresh. oh, and the battery compartment is not the best design; careful when opening so as not to snap off the clips. we've already sent back two i think.
the comm box on the surface ate batteries at a pretty furious rate also. we replaced batteries about every 1.5 days.
good notes: fits a wide range of faces, is very easy to breath. comms are good when the batteries are fresh.
bad notes: tears through batteries. fogs easily and the only remedy is to clear it via standard scuba protocol: flood it and clear it. unfortunately with this, to flood it there is a huge amount of air required to clear it again. i tried using some commercial anti foggers to no avail...
one other note: as i mentioned, comms can be good. if you're using this recreationally, this might mean that your SIGNIFICANT OTHER is talking to you... if you're like me i'm pretty stoked to get them diving so i'm NOT talking to them... ;)
