CH-66
Waterproof and salt water resistant: ideal for marine applications
The CH-66’s extremely rugged housing is waterproof to a depth of 0.5 m and saltwater-resistant. This makes it ideal for outdoor use on seagoing vessels.
A powerful, dynamic transducer serves as both a microphone and a speaker. It ensures excellent speech intelligibility even in noisy environments.
The transmit button is easy to operate even when wearing protective gloves. The entire device is made exclusively of flame-retardant and self-extinguishing materials.
