Simrad xSonic B150M CHIRP Thru-Hull Transducer, 12 Deg Tilt, 95-155 kHz, 300W, Bronze, 9-Pin, 10m Cable, Depth/Temp Sensor

Overview

The Simrad 000-13921-001 is a thru-hull CHIRP transducer with a bronze housing, a 12° tilted element, a black 9-pin connector, and a 10 m (33 ft) cable.

It runs in the Medium CHIRP band from 95 to 155 kHz at 300 W and reports both depth and water temperature. With the 12° housing matched to your hull angle, the sonar beam stays aimed down where it should, which helps with bottom tracking and target separation while you are moving.

Maximum depth performance is rated to 183 m (600 ft), but real-world readings will vary with installation, speed, water conditions, and bottom type.

Key features

• Medium CHIRP coverage from 95 to 155 kHz with 60 kHz of bandwidth from a single transducer
• 300 W power rating for shallow to mid-depth fishing
• 12° tilted element for hull deadrise angles from 8° to 15°
• Bronze thru-hull housing intended for fiberglass or wood hulls, with a low-profile form below the waterline
• Depth and fast-response water temperature sensing in one fitting
• Medium-band beamwidth from 26° to 17° to help separate fish close to structure and in the water column
• Black 9-pin connector and 10 m (33 ft) cable for compatible sonar ports
• 51 mm (2 in) hole size and 66.5 mm usable shaft length to help plan inside-hull clearance

Compatibility and fit

This is a single-channel CHIRP transducer, so your display or sounder needs to support CHIRP and the Medium band to get the full benefit. The connection is a black 9-pin plug, so it is important to confirm your unit has a matching 9-pin transducer socket or that you have the correct adapter for your setup.

The 12° version is meant for boats with 8° to 15° of deadrise at the mounting point. It is commonly used on stepped, planing, and displacement hulls, and it is sized for vessels up to about 8 m (25 ft) in length.

Installation and setup

As a thru-hull, it mounts below the waterline and requires a clean spot that stays in solid water flow. Avoid locations behind strakes, through-hulls, or intakes that can feed the transducer aerated water, and check inside the bilge for access before drilling the 51 mm (2 in) hole.

Plan the cable run before final tightening so the connector can be routed without sharp bends. Leave a little service loop and secure the cable so it cannot chafe from vibration or slap in the bilge.

Use on board

This transducer makes sense for inshore, coastal, and freshwater fishing where you want coverage and clear returns without stepping up to a larger fairing-block install. It suits skippers who run at speed between spots and still want the bottom to stay readable on the way.

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.
