⚠️ Important: Marine vs. IS Model

The standard HX400 (this model) is a commercial-grade radio, but it is not Intrinsically Safe. If you are working on a fuel barge, oil rig, or in a refinery where explosive gases are present, you must use the HX400IS (Intrinsically Safe) version.

The Standard Horizon HX400 Handheld VHF Radio is an excellent choice for boaters and professional operators looking for a rugged, feature-rich VHF solution that combines maritime communication with expandable LMR capability and secure, private voice transmission.
