Raymarine RV-100 RealVision 3D All-In-One Transom Transducer

The Raymarine RV-100 is the all-in-one transducer that pairs with Raymarine Axiom MFDs to give you four sonar technologies from a single transom-mounted unit. Wide Spectrum CHIRP for fish targeting at depth, DownVision for high-detail straight-down imagery, SideVision for lateral coverage out to either side of the boat, and RealVision 3D for stabilized three-dimensional bottom and structure views. If you've got an Axiom and you want full sonar capability without buying separate transducers for each function, this is the unit.

The four channels run simultaneously. You can split-screen the Axiom display with CHIRP fish targeting in one panel, SideVision in another, DownVision in a third, and RealVision 3D in a fourth, all driven by this single transducer. That's the practical advantage of the all-in-one design over single-function transducers: one through-transom install, one cable run, and full sonar capability across the full range of imagery types.

RealVision 3D is the headline feature. It builds an actual three-dimensional view of the bottom and what's on it, with structure, fish, and bait shown in the spatial relationships you'd see if you could look down through the water and around objects. The 3D imagery is meaningfully different from flat sonar in how you understand a wreck, a reef, or a brush pile. You can rotate the 3D view from the Axiom touchscreen to look at the structure from any angle.

The built-in AHRS (Attitude and Heading Reference System) is the technology that makes RealVision 3D usable in real conditions. The AHRS senses the boat's pitch, roll, and yaw and continuously corrects the 3D imagery for boat motion. Without it, the 3D view would jump and distort every time the boat rocked or you turned, making the imagery hard to read in chop or during maneuvers. With AHRS, the 3D model stays consistent in any sea state, which is what makes it actually useful instead of a marketing demo.

DownVision sonar gives you photo-quality straight-down imagery in addition to the 3D view. Different anglers prefer different views for different situations. DownVision is the right call for verifying exactly what's directly under the boat at the moment you're vertically jigging or marking up brush piles. Wide Spectrum CHIRP fish targeting is the traditional 2D sonar that shows fish arches in the water column, which is still the best view for finding suspended fish and reading bottom hardness.

SideVision (also called SideScan in other ecosystems) sweeps the bottom out to either side of the boat at high resolution, useful for finding structure during a search pass without driving over it. The all-in-one transducer covers SideVision out to about 200 feet on each side at typical fishing depths.

The fast-response water temperature sensor is built in. No separate temp sensor to install, no second wire to run. Surface water temperature shows up directly on the Axiom alongside the sonar and chart. For anglers tracking thermoclines, looking for productive temperature breaks, or watching for warming or cooling trends through the day, this saves install time and keeps the wiring clean.

The mounting bracket is marine-grade stainless steel with integrated kick-up. The kick-up is the spring-loaded design that lets the transducer pivot up if you hit floating debris, a rock, or a stump at speed, which prevents the transducer from being torn off the transom. After the impact, the bracket returns to position. Owners who fish unfamiliar water or who run faster than they should occasionally come away from the dock with grateful stories about the kick-up bracket saving an expensive transducer.

The cable is 26 feet (8 meters), terminated in the standard 25-pin Raymarine connector. 26 feet is enough for outboard-powered motorboats up to about 25 feet, with the cable running from the transom up to the helm. For longer boats, the cable can be extended with the appropriate Raymarine extension cable (sold separately).

Compatibility. The RV-100 works with Raymarine Axiom MFDs that support RealVision 3D, which is the standard Axiom and Axiom Pro RVX models. Axiom non-RVX units can use the CHIRP, DownVision, and SideVision functions but require a separate sonar module to access RealVision 3D. Update your Axiom firmware before connecting the transducer.

Mount it. The RV-100 mounts on the transom with the included bracket. Position it in clean water flow, parallel to the boat's running waterline (not the static-at-rest waterline), with a slight downward angle to keep the cone clean at speed. Avoid mounting behind hull strakes, the prop, jet drive intake, or any other water disturber. The included install instructions and template walk you through the right placement on a typical outboard transom.

For bass boats, flats boats, and skiffs running jack plates, the RV-100 detaches from the transom bracket and reattaches to the optional Raymarine stainless jack plate mount (sold separately, A80465). For stepped-hull boats, the optional step-mounting bracket (also sold separately) keeps the transducer in the water through speed transitions.
