Product overview

The GX700B is a full-specification fixed-mount VHF marine radio in a compact form suited to limited dashboard and console space. The rear microphone input socket is a standout installation feature. Most VHF marine radios have the microphone socket on the front panel, which routes the microphone cable into the skipper's field of view. The GX700B adds a rear input: an optional extension cable (5m or 8m, sold separately) runs from the rear of the radio to a flush-mount waterproof socket installed at a convenient vessel location beneath the windscreen, on a side panel, or anywhere the MC616B speaker mic needs to be positioned. The speaker mic plugs into this remote socket rather than hanging from the front panel. A waterproof blanking plug covers the front socket when the rear input is in use. This is particularly effective for above-windscreen installations in hard-top vessels where helm cable clutter is a concern.

25W is the standard maximum output for fixed-mount VHF marine radios, providing communication range of typically 10 to 20 nautical miles under good conditions. The 1W low-power mode suits close-range communication with nearby vessels and reduces power consumption. The large LCD display is readable from any angle in daylight and low-light conditions with adjustable brightness. Dual and triple watch monitor two or three channels simultaneously, keeping Channel 16 the international distress, safety, and calling frequency continuously monitored. Two programmable priority channels and two working channel memories provide quick access to frequently used frequencies. Programmable channel scan stops on active transmissions and returns to scanning when the channel clears. An optional SPK45B extension speaker can be added for audio coverage at a second vessel location.

The GX700B is functionally identical to the GX700W. The choice between the two is based entirely on vessel colour scheme.

Technical specs

Frequently asked questions

What is the rear microphone input and how does it enable above-windscreen installation? Most VHF marine radios have their microphone socket on the front panel, routing the mic cable into the skipper's sightlines. The GX700B adds a rear input: an extension cable (5m or 8m, sold separately) runs from the rear of the radio to a flush-mount waterproof socket at a convenient vessel location. The speaker mic plugs into this remote socket. A blanking plug covers the front socket when the rear input is in use. For above-windscreen hard-top installations, this keeps the helm area clear of cable clutter.

What is the difference between 25W and 1W transmit power? 25W is the full-power output for fixed-mount VHF marine radios, providing communication range of typically 10 to 20 nautical miles under good conditions depending on antenna height. 1W is low-power mode for close-range communication with nearby vessels, reducing interference to other channel users and conserving power on vessels with limited battery capacity.

How does the GX700B differ from the GX700W? The GX700B and GX700W are functionally identical. The GX700B is black; the GX700W is white. Select based on vessel colour scheme and interior aesthetics.

What optional accessories are available for the GX700B? Available accessories include 5m and 8m rear mic extension cables for remote microphone placement, the SPK45B extension speaker for audio at a location away from the helm, and the waterproof blanking plug for the front mic socket. Contact us to confirm current accessory availability.

What channel sets does the GX700B cover? The GX700B includes complete International, USA, and Canadian VHF marine channel sets, covering Australian waters and vessels that operate internationally.
