Marine EPIRB beacons are emergency distress devices that transmit signals to satellites for search and rescue operations. They operate on the 406 MHz frequency, providing accurate location data to rescue authorities. These beacons are waterproof, buoyant, and designed for maritime emergencies.

Marine EPIRB Beacons:

- Size: Typically 30-40 cm in height, 10-15 cm in diameter

- Grade: Compliant with IMO, SOLAS, and COSPAS-SARSAT standards

- Viscosity: N/A (solid-state electronics, no fluid components)

- Buoyancy: Self-righting design, floats upright in water

- Material: High-impact plastic casing, corrosion-resistant metals

- Frequency: 406 MHz (satellite distress signal), 121.5 MHz (homing)

- Battery Life: 48+ hours operational, 5-10 years shelf life

- Operating Temperature: -20°C to +55°C

Marine Communication Systems (VHF Radio):

- Size: Handheld (15-25 cm), Fixed-mount (varies by model)

- Grade: GMDSS-compliant, DSC-enabled

- Viscosity: N/A

- Buoyancy: Handheld models often float, fixed-mount requires separate buoyancy

- Material: Waterproof ABS plastic, stainless steel components

- Frequency Range: 156-174 MHz (marine VHF channels)

- Power Output: 1-25W (adjustable)

- Operating Temperature: -15°C to +55°C
