The multiple function, programmable submersible life vest
The multiple function, programmable, submersible life vest is the first automatic inflating vest available in four modes: Immersion or "Auto" mode and Submersion "Dive" mode, Delayed inflation "Delay" mode, and "Scuba" mode
In Immersion or Auto mode, the MRV is an auto-inflating PFD, and is virtually immune to wave splashes, heavy rain, and high humidity. While a wet environment will not set it off, simply immersing into the water will.
In Submersion or Dive mode, the MRV inflates only
when the user's self-set time and/or depth triggers are exceeded. This valuable delay in
inflation allows for the operator to:
The Depth trigger is valuable when the operator is faced with a rapid sink rate, which can accelerate as he descends into deep water. Even though the time trigger has not been met, exceeding the depth limit will cause inflation.
In Scuba mode, the user may stay underwater as long as the mission requires, however if he exceeds his depth setting, the MRV will fire. This mode is useful in shallow-water tactical rebreather operations.
In Delay mode, users specify the time after they fall into the water before inflation. Often soldiers simply fall or slip into the water and do not want immediate inflation, preferring to self recover by climbing on a boat, or up a bank and thus avoiding unnecessary inflation. The delay time is set by the user. By pushing the remote button, the mode is suspended for one minute allowing operators time to be inserted in deep water, or alternatively to escape a sinking helicopter.
MULTI-FUNCTION REVIEW:Immediate surface inflation: Protection from falling into the water when you want immediate inflationuse AUtO Mode.
Delayed surface inflation: Protection from falling into shallow water when you want a short delay for self rescue, for example falling off the boat into the wateruse dELy Mode.
Sinking too deep, or for too long inflation: Protection from falling into deep water when you want protection from sinking too deep or from being held down too longuse Sub Mode.
Excessive depth protection: When you are in shallow scuba or rebreather ops and you want protection from sinking too deepuse ScbA Mode.
The remote light/switch:
You can cause immediate inflation by pressing the button 4 times rapidly or by simply
yanking on the remote wire.
