What to monitor when installing Raymarine RV transducers
RealVision 3D™ transducers ensure maximum sonar image detail and accuracy only when correctly installed. In addition to the official installation guide, be sure to follow these principles:
1. Choose the correct power supply
Do not connect Axiom Pro RVX-i ega RVX1000 sonar module to the starter motor. The sound generated when the engine starts Ping-pong can To cause the sonar image to be lost, which disrupts the device's operation and navigation.
2. Avoid installation locations that create turbulence
The floor covering must not be installed in the vicinity of air intakes, protruding parts or other obstructions, which can cause Turbulence and air bubbles – these affect sonar image quality.
3. Precise and symmetrical installation is critically important!
-
The hardware must be installed exactly parallel, the same distance from the stern of the boat.
-
If one sensor is ahead of or behind another, The sonar image is shifting..
-
Andurite The distance must not exceed 2 metres (preferably up to 1 metre on either side of the wedge).
4. Depth below the waterline
The doors must be installed at least 300 mm below the water line – during travel, to ensure continuous water contact.
5. Effect of magnetic fields on the AHRS system
On the RV-anduritel Integrated AHRS (Attitude and Heading Reference Sensor), stabilises the sonar image.
-
Avoid installation metal and components with strong electromagnetic radiation nearby (e.g. engine blocks, inverters, chargers, electrical panels).
-
When necessary Turn off the AHRS function from the menu If it does not work correctly due to interference.
RV-412 stainless steel through-hull transducer pair, 12° a plug, 2 m Y-cable and 8 m extension cable
The RV-400 series transducers feature DownVision™, SideVision™, 600-watt high CHIRP sonar, and 3D sonar support. The transducer has a built-in Attitude and Heading Reference System (AHRS) that stabilises the 3D sonar imagery by automatically compensating for the vessel's motion. The RV-400 series also has a built-in fast-response water temperature sensor for quick and accurate readings.
The RV-412 is a pair of port and starboard sensors designed for boats with a deadrise angle of 6° to 18°. Each sensor element is tilted 12° to compensate for the hull's deadrise.
The RV-412 transducers have angled sonar elements within surface-mount housings. The angled elements ensure correct sonar beam alignment for maximum performance while eliminating the drag and turbulence associated with flush-mounting a transducer that has a blocked cover. A Y-cable is included to internally connect the two transducers and an 8-metre RV(M) transducer extension cable.
