The versatile GX400B is the perfect blend of both 27MHz and CB radio frequencies. The GX400B is a versatile marine communication tool featuring both 27MHz Marine Band and 27MHz Citizen Band transceivers in the one unit. Built tough to withstand some of the harshest environments, the GX400B has an IPX7 ingress protection rating meaning it can be positioned on the dashboard by flush mount or gimbal bracket mount as supplied. With a compact mounting depth of only 45mm, it’s possible to mount this compact unit into tight locations where space is limited. For enhanced clarity and ease of use, the GX400B is equipped with dual speakers – one in the front panel and a second built into the waterproof speaker mic. The provision for an additional extension speaker ensures clear audio no matter where you are on the vessel. Featuring programmable channel scanning, dual and tri-watch functions, you’ll never miss important communications. The large red ‘Channel 88’ button enables simple emergency communication in the case of distress. The GX400B is a stylish and versatile addition to your vessel. Also available in white (GX400W).
