Overview

The Garmin 010-11010-01 is a 1 kW through-hull, tilted-element transducer with a 6-pin connector for traditional 50/200 kHz sonar and built-in depth and water-temperature sensing. It’s a low-profile bronze unit that sits nearly flush, with the housing extending less than 6.35 mm (0.25 in) below the hull.

This 12° tilted version is meant to match hull deadrise angles from 8° to 15° so the sonar beam points straight down without a fairing block. It installs through a 95 mm (3-3/4 in) hole, uses a 71 mm (2.80 in) usable shaft length, and comes with a 39 ft cable for reaching the sounder location on many center consoles and offshore fishing boats.

Key features

• 1 kW dual-frequency sonar element (50/200 kHz) for a wide low-frequency view and a tighter high-frequency beam
• Fixed 12° tilted element for 8° to 15° hull deadrise angles
• Low-profile bronze through-hull housing that extends less than 6.35 mm (0.25 in) below the hull
• Depth and fast-response water-temperature sensing in one transducer
• 6-pin connector with a 39 ft cable for direct connection to compatible Garmin sonar ports
• Requires a 95 mm (3-3/4 in) through-hull hole; non-retractable housing

Compatibility and fit

This model is the bronze housing version listed for fiberglass or wood hulls. The 12° tilt is the key fit item: it’s intended for boats with an 8° to 15° deadrise where you want the transducer face angled internally rather than relying on an external fairing.

On the electronics side, match it to a sounder that supports 50/200 kHz and can drive a 1 kW transducer, with a transducer port that accepts the Garmin 6-pin connection.

Installation and setup

Plan the mounting location for clean water flow at speed and enough interior clearance to access the retaining nut and cable routing. A 95 mm (3-3/4 in) hole is a large cutout, so many installs are handled during haul-out with careful measuring, proper bedding, and attention to corrosion control for a bronze fitting in a saltwater environment.

Once installed, route the 39 ft cable away from ignition wiring and high-current runs where practical, then secure it so it cannot chafe in bilges or rigging tubes. After the first few trips, recheck the inside nut area and the seal for any sign of weeping.

Use cases on board

This style of low-profile, no-fairing through-hull is a common pick for fast, trailered fishing boats that need a 1 kW transducer without leaving a tall housing exposed under the hull. It’s also a good fit when you want traditional 50 kHz for depth holding and 200 kHz for clearer target detail while working structure, reefs, and bait schools.

Maintenance and care

Keep the outside face clear of heavy growth, which can soften returns and temperature response. If antifouling is used near the transducer, use products and prep methods that are appropriate for transducers so the acoustic window is not compromised.
