Garmin B164-0 Bronze Thru-Hull Transducer, 1 kW, 50/200 kHz, 0° Tilt, 6-Pin Connector, Depth/Temperature

Overview

The Garmin 010-11010-03 is a 1 kW bronze thru-hull transducer with a Garmin 6-pin connector, built around a 0° tilted element for hull deadrise from 0° to 7°.

It runs traditional dual-frequency sonar at 50/200 kHz, with a wide 22° beam at 50 kHz and a tighter 6° beam at 200 kHz. Depth performance is rated to 549 m (1800 ft) at 50 kHz and 244 m (800 ft) at 200 kHz, and it also includes fast-response water temperature sensing for compatible displays.

The housing sits close to the hull and extends less than 6.35 mm (0.25 in) below it, which helps on boats that get trailered or sit on lifts where protrusions are more likely to get bumped.

Key features

• 1 kW output with traditional dual-frequency 50/200 kHz elements
• 22° beam at 50 kHz and 6° beam at 200 kHz for a mix of broad coverage and tighter target definition
• 0° tilted element intended for install points with 0° to 7° hull deadrise
• Low-profile bronze thru-hull housing that extends less than 6.35 mm (0.25 in) below the hull
• Built-in water temperature sensing (compatible display required)
• Garmin 6-pin connector for direct connection to compatible Garmin sonar inputs

Compatibility and fit

This is a thru-hull style transducer, so fit starts with the hull deadrise at the mounting location. The 0° version is meant for near-flat sections of hull where the deadrise at the install point measures 0° to 7°, keeping the sonar beam aimed close to straight down without adding a fairing block.

Because the housing is bronze, plan for normal below-waterline corrosion practices for your boat, including bonding and appropriate anodes where required by your setup. If your hull is aluminum or steel, confirm the housing material matches your corrosion plan before committing to a thru-hull hole.

Installation and setup

Pick a spot that stays in clean, aeration-free water underway. Avoid areas behind steps, strakes, intakes, and prop wash, since bubbles and turbulence can cause dropouts at speed. Many powerboats place a thru-hull close to the centerline and forward of the engines, while sailboats typically avoid areas where keel or hull turbulence forms.

You will need interior access to tighten the mounting hardware. Use a below-waterline marine sealant and allow full cure time before launching, then verify the reading at the dock and again at cruising speed.

Electrical and system integration

The attached Garmin 6-pin connector plugs into compatible Garmin sonar ports. If your display, sounder module, or wiring harness uses a different connector style, use the correct adapter so the 50/200 kHz sonar elements and temperature lead map correctly to the unit.

Use cases on board

This transducer is a practical match for coastal cruising, offshore runs, and fishing boats that want a higher-power 50/200 kHz setup for bottom tracking and structure work. It also suits trailered and lift-kept boats that need a low-profile thru-hull while still stepping up to 1 kW power.

Maintenance and care

Keep the face clean for consistent returns, especially if the boat stays in the water. If you apply bottom paint, use a product labeled as safe for transducers and avoid building up thick layers on the active surface, since paint buildup can reduce sensitivity.
