Raymarine RVM-400 Series, Installation Instructions Manual, Page: 13 / 58

3.1 Product overview
The RVM-4xx series transducers are RealVision™ Max 3D stainless steel
thru-hull transducers.
In conjunction with a RealVision™ Max 3D compatible multifunction display
or sonar module, the RVM-4xx series transducers produce realistic 3D
representations of the objects below your vessel, to help you identify
underwater structures and locate fish.
RealVision™ Max 3D transducers benefit from improved ping rates and tighter
beamwidths, resulting in sharper sonar images, detailed wrecks, and distinct
fish targets. RealVision™ Max 3D transducers also provide higher contrast
color palettes for accentuating targets, allowing fish targets to stand out
from the water column noise.
Sonar channels:
• RealVision™ Max 3D transducers offer the following sonar channels:
– RealVision™ Max 3D
– SideVision™
– DownVision™
– Conical High CHIRP / Low CHIRP 600 W / 200 kHz
• RealVision™ Max 3D transducers include a built-in AHRS (Attitude and
Heading Reference System) sensor that helps stabilize 3D imaging
automatically, by compensating for vessel motion.
Stainless steel transducers are suitable for installations on vessels with
fiberglass, metal or wooden hulls.
Important:
• When installing the transducer on a vessel that has a metal hull you
must use ALL of the supplied isolator parts to ensure the transducer
metalwork is fully isolated from the metal hull.
• Do NOT install stainless steel transducers on vessels with a positive
ground system.
These transducers are capable of producing 3D sonar images when
connected to a
RealVision™ Max 3D variant MFD running LightHouse™ 4
software, or a LightHouse™ 4 compatible MFD used in conjunction with an
RVM1600 RealVision™ Max 3D sonar module. The RVM-4xx series includes
5 transducer variants, each having the same external shape and dimensions.
The transducers differ internally, and contain different numbers and types
of transmit and receive elements. Your installation should comprise either
a single
RVM-400 transducer, or a split-pair of RVM-412s or RVM-420s
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:
• RVM-400 RealVision™ Max 3D stainless steel 0° (for deadrise 0° to 6°)
thru-hull all-in-one transducer (Part number: A80704)
• RVM-412 Port and RVM-412 Starboard RealVision™ Max 3D stainless steel
12° (for deadrise 6° to 18°) thru-hull split-pair transducers (System pack
part number: T70543)
– RVM-412 Port port transducer (Part number: A80705)
– RVM-412 Starboard starboard transducer (Part number: A80706)
• RVM-420 Port and RVM-420 Starboard RealVision™ Max 3D stainless
steel 20° (for deadrise 14° to 26°) thru-hull split-pair transducer (System
pack part number: T70544)
– RVM-420 Port port transducer (Part number: A80707)
– RVM-420 Starboard starboard transducer (Part number: A80708)
