It supports 25 to 2,000 W RMS sounder power depending on the connected transducer, with selectable transmit power levels and depth capability up to 5,000 ft in suitable conditions.\u003c\/p\u003e\u003cp\u003eThis module is made for boats that need stronger sonar performance than a basic built-in sounder can deliver, especially for fishing, bottom tracking, and reading structure below the hull. It connects to the Garmin Marine Network so sonar data can be shown on compatible networked Garmin displays instead of being limited to one screen.\u003c\/p\u003e\u003cp\u003eThe housing is fully gasketed aluminum and steel with an IPX7 water rating, and the unit accepts 10-35 V DC power for use on common 12 V and 24 V boat electrical systems. Its size is 8 in. x 11.2 in. x 3.2 in., so it is best planned as a fixed installation in a protected, ventilated electronics space.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eGarmin GSD 24 sonar module for compatible Garmin Marine Network chartplotters.\u003c\/li\u003e\n\u003cli\u003eDual-frequency 50\/200 kHz sonar support for traditional fishfinding and bottom detail.\u003c\/li\u003e\n\u003cli\u003e25 to 2,000 W RMS transmit power range, with output dependent on transducer rating and depth.\u003c\/li\u003e\n\u003cli\u003eMaximum depth capability up to 5,000 ft, depending on transducer, water salinity, bottom type, and conditions.\u003c\/li\u003e\n\u003cli\u003e10-35 V DC power input works with typical 12 V and 24 V marine electrical systems.\u003c\/li\u003e\n\u003cli\u003eIPX7-rated housing with fully gasketed aluminum and steel construction for protected marine installations.\u003c\/li\u003e\n\u003cli\u003eSingle Garmin Marine Network port shares sonar information with compatible Garmin displays on the network.\u003c\/li\u003e\n\u003cli\u003e7.5 A fuse rating and 40 W maximum power usage help with electrical planning during installation.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eThe GSD 24 should be mounted where it cannot be submerged, where air can circulate around the housing, and where the status LEDs remain visible for troubleshooting. Leave enough access for the power, network, and transducer cables so the locking rings can be fitted without strain on the connectors.\u003c\/p\u003e\u003cp\u003ePower connection is made to DC positive and ground using the supplied power cable and the required in-line fuse. The network cable connects the module to a compatible Garmin chartplotter or to a Garmin Marine Network port expander, while the transducer connects to the sounder through the transducer port.\u003c\/p\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eThis sounder module is for Garmin Marine Network systems and requires a compatible transducer for operation. Transducer choice matters because transmit power, frequency behavior, mounting style, and final depth performance depend on the transducer and the installation location on the hull.\u003c\/p\u003e\u003cp\u003eThe unit has a compass-safe distance of 15.75 in., which should be considered when placing it near a steering compass or sensitive electronics. For fiberglass mounting surfaces, pilot-hole preparation and careful screw tightening help avoid gelcoat damage.\u003c\/p\u003e\u003ch6\u003eUse on board\u003c\/h6\u003e\u003cp\u003eThis module is a good match for anglers and cruising boats that already use compatible Garmin displays and need a dedicated sonar source for deeper water, structure, reef edges, drop-offs, or general bottom awareness. It is especially useful when sonar needs to be shared across more than one helm or display location through the Garmin Marine Network.\u003c\/p\u003e\u003ch6\u003eWhat’s included\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eGSD 24 sonar module\u003c\/li\u003e\n\u003cli\u003ePower cable\u003c\/li\u003e\n\u003cli\u003eMarine network cable, 6 ft\u003c\/li\u003e\n\u003cli\u003eMounting hardware\u003c\/li\u003e\n\u003cli\u003e8-pin female to wire block adapter\u003c\/li\u003e\n\u003cli\u003eDocumentation\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Garmin","offers":[{"title":"Default Title","offer_id":52715829199029,"sku":"QBP210726","price":599.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1340838_qbp210726.webp?v=1781720210","url":"https:\/\/www.qualityboatparts.com\/products\/qbp210726","provider":"Quality Boat Parts","version":"1.0","type":"link"}
