The transducers differ internally, and contain different numbers and types of transmit and receive
elements. Your installation should comprise either a single RV-400 transducer, or a split-pair of
RV-412(P/S) or RV-420(P/S) transducers.
The hull geometry of your vessel determines the most appropriate transducers to use. You should
fit transducers whose elements are angled to match within ±6° of your hull's deadrise angle, as
detailed below:
• RV-400 RealVision™ 3D stainless steel 0° (for deadrise 0° to 6°) thru-hull all-in-one transducer
(Part number: A80615)
• RV-412P and RV-412S RealVision™ 3D stainless steel 12° (for deadrise 6° to 18°) thru-hull split-pair
transducers (System pack part number: T70450)
– RV-412P port transducer (Part number: A80616)
– RV-412S starboard transducer (Part number: A80617)
• RV-420P and RV-420S RealVision™ 3D stainless steel 20° (for deadrise 14° to 26°) thru-hull
split-pair transducer (System pack part number: T70451)
– RV-420P port transducer (Part number: A80618)
– RV-420S starboard transducer (Part number: A80619)
2.3 Product overview
The RV-4xx series of products are thru-hull mounted RealVision™ 3D sonar transducers, capable
of producing realistic 3D representations of the objects below your vessel, to help you identify
underwater structures and locate fish.
• Stainless steel construction transducers are recommended for installation on vessels with steel or
aluminium hulls.
• Stainless steel construction provides robust and reliable operation.
• 4 sonar channels: DownVision™, SideVision™, CHIRP, and RealVision™ 3D sonar technology
combined in a single unit.
• Powerful and practical sonar operating ranges:
– CHIRP sonar = 0.6 M (2 ft) to 274 m (900 ft)
– DownVision™ = 0.6 M (2 ft) to 183 m (600 ft)
– SideVision™ = 0.6 M (2 ft) to 91 m (300 ft)
– RealVision™ 3D = 0.6 M (2 ft) to 91 m (300 ft)
• Built-in AHRS (Attitude and Heading Reference Sensor) helps to stabilize the sonar imaging,
automatically compensating for vessel motion.
