It runs at 600 W with a listed beamwidth of 24° to 13°, includes a 20 ft (6.1 m) cable, and reads water temperature.\u003c\/p\u003e\u003cp\u003eThis is the style of transducer you install through the hull below the waterline so the element sits in clean water and keeps a consistent bottom picture when you are running or dealing with chop. Maximum depth is listed up to 1,900 ft (579 m) in freshwater, with real-world results depending on hull, mounting location, and water conditions.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eMid-band CHIRP traditional sonar: 85-165 kHz at 600 W.\u003c\/li\u003e\n\u003cli\u003eThru-hull mounting for a stable bottom reading when a transom location gets aerated.\u003c\/li\u003e\n\u003cli\u003eBronze thru-hull housing and stem for below-the-waterline installation.\u003c\/li\u003e\n\u003cli\u003eListed maximum depth up to 1,900 ft (579 m) in freshwater conditions.\u003c\/li\u003e\n\u003cli\u003eBeamwidth 24° to 13° for a mix of coverage and target separation.\u003c\/li\u003e\n\u003cli\u003eBuilt-in temperature sensing for water temp at the display.\u003c\/li\u003e\n\u003cli\u003e8-pin connector with a 20 ft (6.1 m) cable for compatible Garmin sonar ports\/adapters.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003ePlan for a true thru-hull install: drill the hull, bed the stem with marine sealant, and lock the transducer in place using the included anti-rotation hardware so it cannot spin while underway. If your hull is cored fiberglass, the core around the hole should be sealed so water cannot wick into the laminate.\u003c\/p\u003e\u003cp\u003eThe supported deadrise range is listed as 0° to 6°. On hulls with more angle, a fairing block is typically required to keep the element aimed correctly and to seat the hardware properly against the hull surface.\u003c\/p\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eThis model uses an 8-pin transducer connection and is intended for systems that accept Garmin 8-pin sonar inputs (or the correct adapter where applicable). Confirm connector style and sonar support on your display or black box before drilling the hull.\u003c\/p\u003e\u003cp\u003eInstallation instructions cover cored fiberglass, non-cored fiberglass, wood, and metal hulls. Placement matters for clean water flow, so it is worth checking inside access for the backing nut and hardware before choosing the final spot.\u003c\/p\u003e\u003ch6\u003eWhat’s included\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eGT15M-TH transducer\u003c\/li\u003e\n\u003cli\u003eThru-hull mount\u003c\/li\u003e\n\u003cli\u003eMounting hardware\u003c\/li\u003e\n\u003cli\u003eDocumentation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eOn-board use\u003c\/h6\u003e\u003cp\u003eThis is a solid match for boats that spend time fishing structure and want CHIRP traditional sonar with a thru-hull install instead of a transom mount.
