RV-100
Transom-mount four-channel RealVision 3D transducer for outboard boats.
The RV-100 is an all-in-one transom-mount transducer for outboard-powered boats, carrying four channels: CHIRP fish targeting, DownVision, SideVision and RealVision 3D. A built-in attitude sensor (AHRS) steadies the 3D picture against wave and boat motion, and a fast-response sensor reads water temperature. Ranges are 274 m for CHIRP, 183 m for DownVision, and 91 m for SideVision and 3D.
The bracket is marine-grade stainless steel with a kick-up to protect against debris strikes. A jack-plate bracket with spacer kit suits bass boats, flats boats and skiffs, and a step-mounting bracket suits stepped hulls; both are sold separately. The cable is 8 m. It matches the Axiom+ RV, Axiom Pro RVX and RVX1000.

RV-200 Series
Cast bronze through-hull RealVision 3D transducer for inboard and outboard boats; single or paired.
The RV-200 series is the bronze through-hull version of the RealVision 3D transducer, for inboard and outboard powerboats. It carries the same four channels as the RV-100: CHIRP, DownVision, SideVision and RealVision 3D, with a built-in attitude sensor to steady the 3D image and a water temperature sensor. It sits near-flush and needs no fairing block.
The RV-200 is a single transducer with a 0° offset and 8 m cable. For hulls with more deadrise there are 12° and 20° offset versions, as a port and starboard pack with a Y-cable, or as individual port or starboard units. It matches the Axiom+ RV, Axiom Pro and RVX1000.

RV-300 Series
Plastic through-hull RealVision 3D transducer for fibreglass, steel or aluminium hulls; single or paired.
The RV-300 series is the plastic-bodied through-hull RealVision 3D transducer, listed for fibreglass, steel or aluminium hulls. It has the same four channels as the other RV transducers (CHIRP, DownVision, SideVision, RealVision 3D) with a built-in attitude sensor and water temperature sensor. It measures about 310 mm long and weighs 1.5 kg.
The RV-300 is a single 0° unit with an 8 m cable. Angled versions at 12° and 20° come as port and starboard packs with a Y-cable, or as individual port or starboard units, to suit more deadrise. It matches the Axiom+ RV, Axiom Pro and RVX1000. Choose the plastic series where bronze or stainless is not wanted, for example on a metal hull.

RV-400 Series
Stainless steel through-hull RealVision 3D transducer for fibreglass, wood or metal hulls; single or paired.
The RV-400 series is the stainless steel through-hull RealVision 3D transducer for inboard and outboard powerboats. It carries four channels: conical CHIRP fish targeting, DownVision, SideVision and RealVision 3D, plus a built-in attitude sensor and water temperature sensor. It suits fibreglass, wood or metal hulls without a fairing block.
The RV-400 is a single 0° unit with an 8 m cable. For hulls with more deadrise there are 12° and 20° versions, as a port and starboard pack with a Y-cable and 8 m extension, or as individual port or starboard units. It matches the Axiom+ RV, Axiom Pro RVX and RVX1000.

RVM-100
Transom-mount RealVision MAX transducer with 600 W, 200 kHz High CHIRP.
The RVM-100 is the transom-mount transducer for RealVision MAX. Where the RV-100 gives a general four-channel picture, the RVM-100 adds a 600 W conical High CHIRP channel at 200 kHz with a 12° beam, alongside DownVision, SideVision and RealVision 3D. The built-in attitude sensor steadies the 3D view against waves and boat movement, and RealVision 3D range is 91 m.
It is for outboard-powered boats, with a stainless kick-up bracket and an 8 m cable. A jack-plate bracket and a step-mounting bracket are optional. It works with the Axiom 2 Pro and RVM1600. It will not give MAX performance on the older RV modules.

RVM-400 Series
Stainless steel through-hull RealVision MAX transducer, with 600 W High CHIRP.
The RVM-400 series is the stainless steel through-hull RealVision MAX transducer for inboard and outboard powerboats. It has a 600 W conical High CHIRP channel at 200 kHz, plus DownVision, SideVision and RealVision 3D, with a built-in attitude sensor and water temperature sensor. Raymarine quotes CHIRP reach of 365 m, DownVision 182 m, and 91 m for SideVision and 3D.
The RVM-400 is a single 0° unit for hulls under 5° deadrise. The RVM-412 pair (12° tilt) suits 5° to 15° deadrise, and the RVM-420 pair (20° tilt) suits 15° to 25°. Pairs include a Y-cable and an 8 m extension. It works with the RVM1600 and the Axiom 2 Pro RVM.

B260
Bronze through-hull, 1 kW dual frequency (50/200 kHz), suited to bottom fishing; made for the CP370.
The B260 is a bronze through-hull transducer for conventional dual-frequency sonar, listed as made for the CP370. It transmits at 50 and 200 kHz with 1 kW RMS. Beam widths are 19° at 50 kHz and 6° at 200 kHz: the wide low-frequency beam covers more water, the narrow high-frequency beam gives finer detail. Eight internal ceramics give sensitivity in deep water with low ringing, and Raymarine suggests it for bottom fishing.
It suits fibreglass or wood hulls, deadrise from 0 to 20°, with a 9 m cable. It is a sonar-only transducer with no imaging channels. For the imaging transducers, see the RV and RVM series.

B60
Bronze through-hull, 600 W dual frequency with tilted element for 12° or 20° deadrise; for the CP370.
The B60 is a bronze through-hull transducer with a tilted element, which compensates for hull deadrise without a fairing block, and a built-in water temperature sensor. It transmits at 50 and 200 kHz at 600 W RMS, with beam widths of 45° and 12°. It sits nearly flush and is listed for wood or fibreglass hulls.
There are two versions: the 12° model for deadrise of 8° to 15°, and the 20° model for 16° to 24°. Raymarine positions it for inshore or coastal fishing in shallow to medium depths. It fits the CP370 directly, as well as older CP300, DSM300, DSM30 and DSM250 modules. Other systems need adapter cables.

SS164
Stainless steel through-hull, 1 kW dual frequency (50/200 kHz) with tilted element; for the CP370.
The SS164 is a stainless steel through-hull transducer for the CP370. It transmits at 50 and 200 kHz with 1 kW RMS, and works with both 600 W and 1 kW sonar systems. Beam widths are 22° at 50 kHz and 6° at 200 kHz. The tilted element compensates for hull deadrise, so no fairing block is needed, and a built-in sensor reads water temperature.
The low-profile housing protrudes less than 6.35 mm and is listed for fibreglass and wood hulls. Choose the tilt to match the hull: 0° for 0 to 7° deadrise, 12° for 8 to 15°, 20° for 16 to 24°. It uses an 8-pin connector that fits the CP370 and the older CP300, DSM300, DSM30 and DSM250 modules directly.
Getting this wrong is the usual reason a good sounder reads badly. We match the transducer to the hull and the module before quoting.
