Standard Horizon HX400IS Intrinsically Safe Handheld VHF Case of 20

The Standard Horizon HX400IS Intrinsically Safe Handheld VHF, Case of 20 (MPN HX400ISCASE) is a bulk case of 20 of the HX400IS, Standard Horizon's intrinsically safe handheld VHF radio. The case format is designed for commercial buyers, fleet operators, charter companies, marine industrial operations, harbor crews, and any organization that needs to outfit a team with IS-rated handheld VHF in a single purchase rather than ordering radios one at a time.

Why intrinsically safe matters. Intrinsically safe (IS) is a regulated electrical safety category that means the device is engineered so it can't generate the spark or thermal energy needed to ignite flammable atmospheres. For marine commercial operations around fuel handling (tank cleaning, fuel barges, refueling operations), petrochemical waterfront facilities, hazardous cargo loading, and any other environment where flammable vapors might be present, only IS-rated equipment is legally and operationally usable. A standard handheld VHF in those environments is a safety violation. The HX400IS is the IS-rated answer.

What submersible IPX8 actually means. The HX400IS is rated IPX8 to 1.5 meters (4.92 feet) for 30 minutes. That's not splash-proof or water-resistant, that's actual submersible. If the radio gets dropped overboard, you can retrieve it from the bottom up to 1.5 meters and it still works. For commercial marine use where radios get wet daily and occasionally dunked, IPX8 is the operational standard that keeps fleets running without constant radio replacement.

Transmit power and battery. The HX400IS provides selectable 5-watt or 1-watt transmit power, with the 5-watt setting delivering full-power marine VHF range for safety communications and the 1-watt setting extending battery life and reducing range when close-range communication is sufficient. The supplied 2550mAh lithium-ion battery delivers approximately 17 hours of typical use, and the included three-hour rapid charger (both AC and DC versions) means crews can cycle radios through shift changes without battery downtime.

Land Mobile Radio capability. Beyond the standard marine VHF channels (USA, Canadian, International, and NOAA Weather with weather alert), the HX400IS supports 40 dealer-programmable Land Mobile Radio channels in the 134-174 MHz band with CTCSS or DCS signaling. For commercial operations that combine marine and land-mobile communications (port operations spanning water and dock, multi-site industrial operations, security teams covering waterfront and shore-side facilities), the single-radio LMR capability eliminates the need for separate handhelds for the two networks. Note that LMR channel use requires the appropriate Federal Communications Commission license.

Noise canceling and voice scrambler. Built-in noise canceling microphone for clear communication in windy and noisy environments (engine room, dock operations, helicopter operations). Built-in 4-code voice scrambler compatible with Standard Horizon's fixed-mount and handheld VHF scramblers, for secure communications without buying a separate scrambler accessory. For commercial users who need both clear and private communications, both features standard on the HX400IS.

Loud speaker audio. 700 milliwatts of power supplied to the internal speaker, designed to be heard in even the noisiest environments. Optional speaker microphones and headsets are available for specific operational needs, but the built-in speaker handles most commercial use without accessory dependence.

Distress strobe. Unique super-bright LED distress strobe light built into the radio body. For man-overboard scenarios, low-visibility night operations, or any emergency where visual signaling matters, the integrated strobe is operationally useful and doesn't require a separate piece of safety gear hanging off the operator. One radio handles communications and visual distress signaling.

Scan and channel management. Programmable scan, priority scan, and dual watch for monitoring multiple channels simultaneously. Preset key recalls up to 10 favorite channels for quick access to operationally critical frequencies. Programmable channel names so users see meaningful names (DOCK-OPS, SECURITY, EMERGENCY) instead of just channel numbers. Key lock prevents accidental setting changes during use.

What's in the case. Twenty HX400IS handheld VHF radios, each with the standard supplied kit including the 2550mAh lithium-ion battery, AC and DC three-hour rapid chargers, antenna, belt clip, and documentation. The case format is intended for direct deployment to fleet or team members rather than retail individual sale.

Who buys a case of 20. Commercial marine fleet operators (charter companies, tow boat operators, work boat fleets, fishing fleets). Marine industrial operations (fuel barge operators, tank cleaning contractors, port-side petrochemical facilities, ship repair yards). Harbor and port authority operations. Marine security and law enforcement teams. Large yacht owners outfitting a crew. Any organization that needs to standardize a fleet of IS-rated handheld VHF in a single procurement event.

Why pay this much. The case-of-20 pricing reflects bulk procurement economics for the HX400IS, which is the intrinsically safe handheld VHF that commercial marine and industrial waterfront operations actually use. The IS rating is the legal requirement for hazardous-atmosphere operations, not an optional feature, so the price floor reflects the certification work behind the IS rating, not just the radio hardware. For organizations that need to outfit twenty operators with IS-rated handheld VHF, the case format eliminates twenty separate procurement events and standardizes the entire fleet on one radio model with consistent training, accessories, and maintenance.
