Overview

The Simrad 000-13914-001 is an in-hull, 1 kW 50/200 kHz sonar transducer with a 9-pin xSonic connector for depth-only sounders.

It runs two frequencies: 50 kHz with a 19° beam for broader coverage and deep-water work, and 200 kHz with a 6° beam when you want a tighter cone for more defined returns. The element stack uses seven ceramics for the 50 kHz array plus a single 200 kHz element, for a total of eight internal ceramics.

This model installs inside a solid fiberglass hull using a bonded tank that is cut to match the hull deadrise (up to 30°). You avoid external drag and you keep the transducer protected from trailers, debris, and dockside bumps. It is commonly chosen on sportfishing and light commercial boats from about 8 m (25 ft) and up.

Key features

• 50/200 kHz depth-only transducer with 19° beam at 50 kHz and 6° beam at 200 kHz
• 1 kW power rating for conventional 50/200 kHz sounders
• In-hull tank installation for solid fiberglass hull sections, with the tank cut to match deadrise up to 30°
• Eight internal ceramics (seven for 50 kHz plus one for 200 kHz)
• 9-pin xSonic connector for compatible Simrad sonar ports
• Fits existing installed M260 in-hull tanks when retrofitting
• Commonly paired with SonarHub and Simrad NSSevo3 family displays when used with a supported sounder channel

Compatibility and fit

Because this is an in-hull installation, the mounting location needs to be a solid fiberglass section of hull with good water contact and no air pockets under way. The tank is trimmed to match the hull angle at the mounting spot, up to 30° deadrise, so the element can sit level and read cleanly.

On the electronics side, confirm your sounder supports a 1 kW 50/200 kHz transducer and has the matching 9-pin xSonic transducer port, or the correct adapter for your system. This transducer reports depth only, so it is not meant to provide speed or water temperature.

Installation and setup

The tank is bonded inside the hull using fiberglass resin, then filled with non-toxic propylene glycol so the transducer face stays coupled to the hull without air gaps. Take time on placement and leveling, since small voids or a location that aerates at speed can show up as bottom dropouts.

Route the cable away from ignition wiring, high-current battery runs, and other noise sources where possible. Leave a service loop so the transducer can be removed from the tank for troubleshooting without redoing the tank bond.

Use on board

This setup is a good match for skippers who want a 50/200 kHz depth channel without a through-hull fitting, especially on boats that see trailering, rough docks, or areas with floating debris. It also suits offshore runs where the 50 kHz beam is used to hold bottom deeper, while 200 kHz is kept for tighter cone work over structure in shallower water.
