Raymarine Transducers

Installing the right type of depth Transducer is crucial to getting the most out of your Raymarine HD Digital Fishfinder. Raymarine offers a wide Range of Transducers suitable for a variety of vessel types and performance requirements.

When trying to determine which Transducer is best for you, you’ll need to consider the following variables:

• What material the Transducer housing is made of, based on Boat Hull composition
• How the Transducer should be mounted on the boat: in the Hull, through the Hull, or on the transom
• What you want to see displayed: depth, speed, temperature, or a combination

Plastic housings are recommended for Fiberglass or Metal hulls.
Bronze housings are recommended for Fiberglass or wood hulls. Bronze is preferable to plastic for wooden hulls because the expansion of wood could damage a plastic Transducer and cause a leak. A Metal housing should NOT be installed in a vessel with a positive ground system.
Stainless Steel housings are recommended for steel or aluminum hulls.

Transducer Power

Power refers to the strength with which the Transducer sends the Sonar “ping”, expressed as Watts RMS. Higher power increases your chances of getting a return echo in deep water or poor water conditions. It also lets you see better detail, such as bait Fish and structure. Generally, the more power you have, the deeper you can reach and the easier it is to separate echoes returning from Fish and bottom structure from all the other noises the Transducer detects.
