Standard Horizon HX400IS Intrinsically Safe Handheld VHF

The Standard Horizon HX400IS is an intrinsically safe handheld VHF designed for demanding commercial environments where rugged construction and dependable communications matter. Its submersible construction is rated IPX8 to 1.5 meters for 30 minutes, and selectable 5- or 1-watt transmit power lets the operator balance maximum output with lower-power operation when appropriate.

A built-in noise-canceling microphone helps improve voice clarity in noisy working conditions, while the voice scrambler adds privacy for compatible communications. In addition to marine channels, the HX400IS can be dealer programmed with up to 40 land-mobile channels from 134 to 174 MHz with CTCSS and DCS signaling, making it useful for operations that rely on both marine and land-mobile communications.

The supplied 2550mAh lithium-ion battery is rated for about 17 hours of operation, and both AC and DC three-hour quick chargers are included to support faster turnaround between shifts. NOAA weather channels and weather alerts, programmable scanning, priority scan, Dual Watch, a preset key for favorite channels, and the built-in distress strobe round out a feature set aimed at commercial crews and other demanding users.
