VHF55S INTRODUCTION

The Humminbird® VHF55S represents state-of-the-art high tech VHF Handheld engineering, and is skillfully designed and constructed with the finest components. It is constructed to commercial- grade standards to give you clear, reliable communication.

The Humminbird® VHF55S is available in three different versions:

•VHF55S.

•VHF55SC Camouflage.

•VHF55S Plus.

HOW VHF WORKS

The most popular method of communicating with other boats is via very high frequency (VHF) radio. In technical terms, this is similar to the way that commercial radio stations transmit. VHF equipment is relatively simple, and can therefore be compact and low cost.

To ensure that maritime users do not cause interference for other radio users, a part of the radio spectrum has been allocated specifically to this group of users. These reserved frequencies have been numbered; for example, Channel 16 (usually abbreviated Ch16) actually refers to a frequency of 156.800 mHz.

Because radio does not recognize geographic or political boundaries, and to make sure that boats traveling on international voyages can always communicate, the VHF marine band is the same worldwide. There are 55 international marine channels, a similar number of private channels (allocated on a local basis to commercial organizations) and some other unique national channels.

The United States and Canada employ a slightly different application of marine channels, using the same frequencies but allocating more simplex (one-way) rather than duplex (two-way) channels.

National channels include WX (weather) channels in the U.S., fishing channels in Norway and the marina channels M and M2 in the U.K. To make sure that your radio is fitted with the correct local channels, be sure to purchase type-approved equipment in the country of intended use.

The VHF55S operates on all international VHF marine channels, offering full coverage and ensuring that boaters can communicate effectively with other vessels and shore stations. Its powerful 25-watt transmit power guarantees clear communication over long distances, making it ideal for offshore adventures.

Another significant aspect of the VHF55S is its intuitive interface, designed for user-friendly operation. The large, bright LCD display ensures visibility even under bright sunlight or at night. The radio is equipped with large buttons that facilitate quick access to commonly used functions and channels, minimizing the learning curve for new users.

In addition to its core functionalities, the VHF55S features advanced scanning capabilities, allowing users to monitor multiple channels simultaneously. This ensures that no important communications slip through the cracks, which is particularly advantageous during busy boating seasons or when navigating crowded waterways.

The Humminbird VHF55S is built to withstand the harsh marine environment. Its rugged design features a water-resistant housing, making it resilient against splashes and the dampness often encountered on the water. Furthermore, the unit is compact and lightweight, allowing for easy mounting in various locations on a boat without occupying too much space.

For connectivity, the VHF55S allows integration with other marine electronics, such as chartplotters and GPS devices. This capability enhances situational awareness and aids in navigation by providing real-time communication data and positioning information.

In summary, the Humminbird VHF55S is a state-of-the-art marine VHF radio that combines essential safety features, advanced communication technologies, and a user-friendly design. With DSC capability, robust construction, and versatile functionality, it is an indispensable device for anyone navigating the waters, ensuring that users remain connected and safe at sea.
