This life preserver can take a direct hit from a fire arm or fragment and still inflate. The unique damage tolerant design makes this PFD well suited for use in high risk tactical situations. The 65 lb. buoyancy provides extra flotation to compensate for the personal equipment and arms carried on missions. This universal size PFD can be integrated with most ballistic vests and comes with a harness. (US Patent 6,453,840)

The MD4020 Marine DTLP is designed for tactical boarding parties, and uses Auto Hydrostatic inflator technology HiT™. In the event of accidental immersion, the DTLP automatically inflates and self-rights an unconscious user. For missions that require manually activated inflation, the optional MA7219 conversion cap can reconfigure the PFD from automatic to manually activated inflation.

Life Preserver Inflatable Cells and Restraint Layer

Each DTLP contains two inflatable cells. The cells are made from polyurethane coated nylon fabric. Both versions are inflated using CO2 to inflate either cell. If one cell is compromised prior to inflation, the functional redundant cell can be inflated maintaining full flotation performance.

The MD4020 uses a Hammar hydrostatic inflator that activates automatically upon entry into the water yet remains impervious to high humidity, heavy rain or waves. The MD4025 FR must be actuated manually. Both models may be actuated manually by pulling on the beaded handle for either chamber. Inflating either one or both chambers provide full function of the device for operational use. Both chambers have oral inflation backup and pressure relief valves to prevent over-inflation. The larger buoyancy models come equipped with a dump valve that allows emergency deflation and improved mobility if needed. When inflated, the cell forms a yoke around the back of the user's neck, extending into two lobes down the user's chest. The inflatable cells are contained within a protective restraint, and can be easily replaced or repaired. The DTLP comes standard with a SOLAS signal whistle, sea light, buddy line, lifting strap and SOLAS-grade retro-reflective tape. The inflatable cell restraint layer comes standard in high-visibility international orange, but is available in subdued colors to meet covert operational requirements.

Maritime DTLP Re-arm Kit is available. Note: 2 kits required if both cells inflate.
