Furuno Transducers

Furuno has a serious reputation among offshore and commercial crews for sounders that mark fish and bottom in deep water, and the transducer is the front end of that performance. This collection covers Furuno transducers, many of them Airmar-built, in thru-hull, transom, and pocket-mount styles. Choosing right comes down to matching the transducer to your Furuno sounder, picking the frequencies and power for your depth, and selecting the mount for your hull.

Match the transducer to your Furuno sounder

The transducer has to pair with your specific Furuno sounder or DFF black box and use the correct connector and pin count, commonly 10-pin or 12-pin. Furuno lists the compatible transducers for each sounder, so confirm your model before you buy. Matching the transducer to the sounder is what unlocks the unit's full depth and detail, and the wrong one simply will not perform. Always check the model number on your sounder or black box first.

Frequency, CHIRP, and power

CHIRP transducers sweep a band of frequencies for sharper detail and target separation than a single ping. Higher frequencies sharpen shallow detail, while lower frequencies and more power reach deep, which is why offshore and commercial boats run high-power 1kW and 3kW thru-hull transducers to mark bottom and bait in hundreds or thousands of feet. Match the power and frequency to how deep you actually fish. Single-frequency models still work well for many inshore applications where simplicity matters more than maximum range.

Thru-hull, transom, or pocket mount

Thru-hull transducers, often bronze or stainless, give the cleanest high-speed signal for offshore boats but need a hole and sometimes a fairing block. Transom mounts are simpler for smaller and trailered boats. Pocket-mount and tilted-element transducers fit specific hull deadrise angles so the face shoots straight down. Match the mount to your hull and how you run. Each style has trade-offs in installation effort and signal quality at speed.

Plan the install

High-power transducers are an investment, so plan the location for a clean signal away from hull turbulence and running gear. A bronze thru-hull on a deadrise hull usually needs a fairing block to aim the beam down, and getting the placement right is half the performance. Our techs can advise on the best spot for your hull. Take time to review your boat's layout and running habits before drilling or bonding anything in place.

Not sure which Furuno transducer fits your sounder? Tell our techs your Furuno model and hull, and we will match the transducer frequency, power, connector, and mount so you get the deep, clean returns Furuno is known for. Proper selection avoids wasted time and money on returns or poor performance on the water.
