NOTE: AIRMAR NO LONGER MANUFACTURES THIS PRODUCT

Airmar has now made it possible for saltwater fishermen to “widen up” the high-frequency, 200 kHz performance for most of today’s popular fishfinders. The SB264 connects your existing, 1 kW, Airmar transducer and a newly-installed SS264W for wide and narrow-beam selection at your fingertips. The switchbox works with most of Airmar’s 1 kW transducers including the B260, M260, B258, and B256 found on boats from center consoles to large, sportfishing vessels.

Installers can leave any of these models in place and mount an additional SS264W Tilted Element™ transducer, then wire both into the SB264. The waterproof panel-mount switch is easily installed and takes minimal space. This lets the operator toggle between 200 kHz wide (25°) or narrow-beam (6°) fish finding, together with the 50 kHz low-frequency operation.

Traditionally at 200 kHz, most transducers have a narrowly focused beam in which fish swimming near the boat can go un-marked because they are outside of the transducer beam. At 50 kHz, the beam is wider, thus marking more fish, but resolution and detail are not as crisp. Tightly-spaced fish tend to appear on the fishfinder screen as one large target or “blob". The SS264W, 200 kHz, transducer provides the coverage and resolution needed so that fishermen do not miss any fish or bait lurking close to the boat. Additionally with the, tightly-spaced fish appear on the fishfinder screen more as individual targets and as arches.

Wide-beam, 200 kHz operation is great when trolling or searching for fish in the mid to upper portion of the water column. This makes it ideal for tuna and marlin fishing. Switching to a more traditional, narrow-beam, 200 kHz operation works best when bottom fishing for cod or grouper in waters up to 122 m (400'), providing optimal bottom detail and separation between the bottom and tightly-spaced fish targets. A narrow and wide beam, 200 kHz combination on the boat caters to the versatile fisherman who may be bottom fishing with a narrow beam in the morning and tuna or marlin fishing with the SS264W, 200 kHz by afternoon.

NOTE: AIRMAR NO LONGER MANUFACTURES THIS PRODUCT

This switchbox can be used to switch between two fishfinder transducers connected to one sounder, so that you can select the transducer that is appropriate for different fishing conditions. It comes with a panel-mount waterproof switch. The SB260 can be used with any two of the current range of 1kW fishfinder transducers from Airmar. It will work with certain newer 600W models - contact us with information on the transducers you want to switch. The SB260 can also be used with one fishfinder transducer and two sounders, to feed the transducer signal to either one sounder or the other.

The Airmar GH2183 combines GPS positioning and highly-accurate heading information in one compact antenna. The GH2183 eliminates the need to install a GPS antenna above deck and a heading sensor below deck. Only one, above-deck installation is required, saving installation time and money. The waterproof housing protects the internal components—all of which are solid-state (no moving parts). This means the GH2183 can withstand almost any condition that exists in the marine environment.

The best performance in ANY sea condition!

What sets the GH2183 above the competition is our 2° heading accuracy in dynamically changing conditions—including rough seas, hard turns, and steep heeling. Airmar’s unique dynamic motion correction software is the key difference, allowing the GH2183 to maintain 2° of accuracy even if the vessel is pitching and rolling up to 30°. Also unique to the GH2183 is that the three-axis accelerometer and three-axis rate gyro are temperature compensated across the entire operating range, resulting in precise tilt and rate of turn data. The fast 10 Hz update rate, along with best-in-class heading and GPS data, make it the best choice for interfacing with autopilots, chartplotters, navigation software, and radar systems.

Whether you are offshore fishing or just enjoying family time on the water, feel confident and comfortable that the H2183 is your reliable source for heading information. The solid-state, three-axis compass combined with Airmar’s additional advanced sensors and software provide unparalleled performance.

What sets the H2183 apart from the competition is its ability to maintain 2° of heading accuracy under dynamic motion conditions such as steep heeling, hard turns, and rough seas. Heading integrated with three-axis rate gyro and three-axis accelerometer data allows the H2183 maintain 2° of accuracy even if the vessel is pitching and rolling up to 30°. This level of accuracy is perfect for interfacing with autopilots, chart plotters, and radar systems. The H2183’s innovative circular design easily mounts and aligns on ANY angled bulkhead. Designed for simultaneous use with NMEA 0183 and NMEA 2000® devices, the waterproof, easy-to-install sensor can be wired into both NMEA 0183 and NMEA 2000 networks on the vessel with just a single cable.

The G2183 is a highly-accurate GPS antenna—WAAS / EGNOS enabled. It is one of the first true 10Hz GPS Antennas made available. Scoring high in sensitivity, it delivers quick signal acquisition, reliable positioning, and accurate speed and course-over-ground readings.

NOTE: AIRMAR NO LONGER MANUFACTURES THIS PRODUCT

Airmar’s R299 is radically different. Why? Because it operates at ANY frequency between 33 kHz to 60 kHz and 130 kHz to 210 kHz. Adjusting the frequency allows you to change the R299's Beamwidth and depth capabilities. For example, if you are bottom fishing in 61 m (200') of water, the narrow high-frequency beam will display extreme bottom detail and fish holding tight to structure. If you are tuna or marlin fishing in deep blue water, the wider, low-frequency beam will not only give deep-water bottom detail, but more importantly show you what is around your vessel—including bait which may attract game fish. Widen the band and increase the catch with the R299.

Because the R299 has a bandwidth that covers a continuous frequency spectrum, next generation fish finders can be made “tunable”, so fishermen can “dial-in” the best frequency for the target-fish species or conditions.

The M265LM Chirp-ready transducer is a perfect mid to deep-depth transducer. The huge bandwidth includes many of the most popular frequencies for targeting top gamefish. This 1 kW powerhouse transducer delivers clear target details, bottom discrimination, as well as bait and game-fish separation at all depths. The low-frequency band provides deep-water performance down to 914 m (3,000') and is a good choice when scouting an area or fishing in deeper depths. The medium-frequency band is excellent for identifying targets suspended close to the bottom on structure and within the water column.

The Sealcast™ M265LM includes a plastic tank which is aligned to the centerline and secured inside the hull. Then it is filled with non-toxic antifreeze. The transducer is inserted into the tank and adjusted for the proper deadrise offset, insuring the beam is shooting straight down for maximum echo returns. Antifreeze is the best medium to transmit through solid fiberglass and into the surrounding water. The major benefit of an in-hull transducer is no protruding features on the exterior of the hull, making it the perfect choice for trailered or lifted boats. Designed for boats up to 11 m (36') with a solid-fiberglass hull.
