Bronze Thru Hull Transducers - Depth, Speed and Temperature, RAY A66091

Choose a transducer compatible with the Raymarine Series product you own; see table. Transducer kits come with installation instructions. Please follow these instructions carefully to ensure proper operation.
• Transducers only provide raw data, and must be connected to a processor (usually a depth sounder with a display, or a “black box” module) in order to display depth, speed, etc. Depth transducers are commonly available in 50/200 KHz (deep/shallow water) and 200 KHz (shallow water, less than 600 ft.) models
• Transducers with 0° of element tilt must be mounted so they point straight down; if the hull is curved or angled, they often require fairing blocks to achieve this. Transducers showing a range of element tilt angles (relative to the hull) can be set to a particular angle within that range at the time of installation. This can eliminate the need for using a fairing block when mounting on a curved or angled hull
• Models E26030, E66071, and M78717 have a removable core which can be replaced with a plug for safety
• Typical beam angles: 200 kHz 12°, 50 kHz 45°
• Replaceable/removable paddle wheel in speed transducers
• Hull material: wood - use a bronze transducer
• Hull material: fiberglass - use any transducer material
• Hull material: aluminum - use a plastic transducer
