Overview

The Garmin 010-10182-01 is a bronze thru-hull transducer that delivers traditional 50/200 kHz sonar plus water-temperature data through a 6-pin connector. It is rated at 600 W, with a 45° beam at 50 kHz for broader coverage and a 12° beam at 200 kHz for tighter bottom detail.

This is a low-profile “mushroom” style install with about 5 mm (3/16 in) outside the hull, which helps keep drag down on boats that run at speed. It is intended for fiberglass and wood hulls with a deadrise around 0–7°, uses a 39 ft (12 m) cable, and fits a 2 in (51 mm) thru-hull hole.

Bronze housings are not a fit for metal hull installations, where corrosion control and housing material choices are different.

Key features

• Dual-frequency 50/200 kHz sonar with 45° (50 kHz) and 12° (200 kHz) beamwidth
• 600 W power rating for depth sounding, with depth performance that can reach about 366 m (1,200 ft) at 50 kHz and about 213 m (700 ft) at 200 kHz in good conditions
• Depth and fast-response water-temperature sensing in one thru-hull transducer
• Low-profile bronze housing with about 5 mm (3/16 in) proud of the hull to reduce drag
• 6-pin connector and 39 ft (12 m) cable for runs from bilge to helm or sounder module
• Recommended for fiberglass and wood hulls with approximately 0–7° deadrise

Installation and setup

Plan the mounting spot in clean water where the transducer face stays submerged and clear of prop wash, strakes, and turbulent flow. A straight shot from inside the hull matters too, since you need room to seat the housing, apply the correct bedding compound for a below-waterline bronze thru-hull, and fully tighten the hull nut.

The 2 in (51 mm) hole size makes this a more committed install than a transom mount, so many owners install it during haul-out. After bedding and tightening, route the cable with a drip loop and keep it away from high-current runs when possible to help prevent noise in the sonar return.

Compatibility and fit

The 6-pin plug matches Garmin sounders and modules that use a 6-pin transducer port. If your sonar hardware uses a different connector style, the fit is handled with the appropriate adapter cable so the transducer and the port match correctly.

This transducer is tuned for hulls with lower deadrise angles; on steeper deadrise hulls, a tilted-element style is typically used to keep the sonar beam closer to vertical.

Use cases on board

This style of transducer is a solid match for coastal cruising and offshore fishing boats that want dependable bottom tracking and water temperature without adding drag or a large fairing block. It also makes sense on sailboats and smaller powerboats where a nearly flush thru-hull keeps the underside clean around trailer bunks and rollers.
