Simrad TM150M Transom Mount CHIRP Transducer, Medium CHIRP 95-155 kHz, 300W, 26-17 Degree Beamwidth, Depth/Temp Sensor, 9-Pin, 10m Cable

Overview

The Simrad 000-13944-001 is a TM150M transom mount CHIRP transducer with a 9-pin connector and a 10 m cable for Medium CHIRP sonar (95-155 kHz) at 300 W.

It reads depth and water temperature from one housing, and the beam tightens from 26 to 17 degrees across the band, which helps keep fish marks separate when you are working structure, bait schools, or suspended targets.

This style of transom mount install is common on planing hulls with outboards or sterndrives, and it is typically used on smaller boats up to about 8 m (25 ft) where easy access and adjustability matter.

Key features

• Medium CHIRP 95-155 kHz with a 60 kHz sweep for one-channel fishfinding.
• 300 W rating with beamwidth that narrows from 26 to 17 degrees across the band.
• Integrated depth and fast-response water-temperature sensing through the same transducer.
• Transom-mount format suited to planing hulls and common outboard or I/O setups.
• Urethane housing with a release-style bracket that helps protect the transducer if it strikes an obstruction.
• Works on fiberglass, wood, aluminum, or steel transoms when mounted in clean water flow.
• 9-pin connector with 10 m (33 ft) attached cable for routing back to your sounder or sonar module.

Compatibility and fit

This transducer outputs sonar and temperature data through a 9-pin connector. Confirm that your display or sonar module has the matching 9-pin transducer port and supports Medium CHIRP (95-155 kHz). If your unit uses a different connector style, an adapter may be required.

It is intended for a transom angle in the 3 to 20 degrees range. Boats with stepped hulls, heavy aeration, or tight engine brackets may need extra care in placement to keep the transducer in solid water at speed.

Installation and setup

Mount it where the face stays submerged when the boat is on plane, and where prop wash, strakes, and thru-hull turbulence will not feed bubbles across the bottom of the transducer. A small height change makes a big difference, so plan to fine-tune after the first sea trial.

Route the cable away from ignition wiring and high-current runs when possible, leave a drip loop at the connector, and seal any deck pass-through with a proper gland so washdowns do not follow the cable inside.

Use cases on board

This setup fits inshore, coastal, and freshwater fishing boats that need clear CHIRP target separation around reefs, points, docks, and drop-offs, while keeping the simplicity of a transom mount that is easy to inspect and adjust.

Maintenance and care

Rinse after saltwater use and keep the acoustic face free of barnacles and heavy buildup. Mild soap and water is usually enough for cleaning.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
