The ACR EPIRB1 Pro Emergency Beacon operates on the 406MHz satellite band. This band contains the international distress frequencies, which are frequently monitored by Cospas-Sarsat, the international search and rescue satellite operators, to ensure a prompt response when a signal is received, regardless of where it is received throughout the world.
The ACR EPIRB1 Pro Emergency Beacon is the world's smallest EPIRB, and it combines its compact size with a durable design to make it a valuable solution for all commercial, fishing, and pleasure vessels. With a 10-year battery life and great functional life when activated, the device has been designed for maximum efficiency, keeping rescue services informed of your whereabouts for a longer amount of time.
A 121.5MHz homing beacon is included in this EPIRB, which is used by rescue personnel to determine the exact location of vessels in distress. Additionally, the EPIRB has a high-intensity LED strobe light for increased visibility, especially at night. For emergency situations where a user is not physically able to access the EPIRB in time, the EPIRB1 Pro has a Category I Automatic Release Housing (commonly referred to as 'float free'). The EPIRB is automatically launched from the bracket, triggered, and floats to the surface to broadcast your distress message to the satellite network, thanks to the built-in Hydrostatic Release Unit.
The Automatic Release Housing (ARH) also includes a useful adapter on the EPIRB1 Pro that enables a number of refit options. The ARH may be simply mounted using the same mounting holes as previous and larger EPIRBS, such as the Ocean Signal E100/E100G, Jotron Tron 60s, and McMurdo E5/G5.
