On the temperature side, it measures water temperature from -10°C to 40°C (14°F to 104°F) with ±0.5°C (±1.8°F) accuracy, and it is powered from the NMEA 2000 network at 9 to 16 V DC (4 LEN load).\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eDepth and water temperature data on NMEA 2000 using standard PGNs\u003c\/li\u003e\n\u003cli\u003e0° element suited to hull deadrise angles from 0° to 7°\u003c\/li\u003e\n\u003cli\u003e51 mm (2 in) plastic flanged through-hull housing for a clean, permanent install\u003c\/li\u003e\n\u003cli\u003e2 m NMEA 2000 Micro-C lead for a straightforward drop to the backbone\u003c\/li\u003e\n\u003cli\u003eRuns from the network at 9 to 16 V DC and draws 4 LEN for power budgeting\u003c\/li\u003e\n\u003cli\u003e235 kHz sounding with a 12° beam and depth capability up to 180 m (590 ft)\u003c\/li\u003e\n\u003cli\u003eRetractable insert with an internal valve to reduce water flow when the insert is removed for cleaning\u003c\/li\u003e\n\u003cli\u003eNo speed sensor connection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eThis is the 0° version, so it matches a near-flat mounting surface where hull deadrise falls between 0° and 7°. If the chosen area has more deadrise than that, the beam will not be aimed straight down and the readings can suffer, especially at speed.\u003c\/p\u003e\u003cp\u003eOn the network side, it behaves like a standard NMEA 2000 depth and temperature device, so any compatible display or instrument that reads those PGNs can show the data. If your boat runs a 24 V house system, the NMEA 2000 backbone still needs the usual 12 V class supply (within 9 to 16 V DC).\u003c\/p\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eThis sensor is a true through-hull fitting, so placement matters. Mount it where the water flow stays clean and free of bubbles, away from strakes, steps, intakes, and prop wash, and where you can reach the retaining nut and cable route inside the hull.\u003c\/p\u003e\u003cp\u003eThe retractable insert helps with service and seasonal cleaning. When growth builds up on the face, the insert can be removed and cleaned, and the valve in the housing limits water entering the boat during that short maintenance window.\u003c\/p\u003e\u003ch6\u003eElectrical and system integration\u003c\/h6\u003e\u003cp\u003eConnection is via the attached Micro-C lead into a standard NMEA 2000 T-connector on the backbone. Account for the 4 LEN draw in your network load calculation and make sure the backbone is properly powered and terminated so the depth and temperature data stays stable across the bus.\u003c\/p\u003e\u003ch6\u003eUse cases on board\u003c\/h6\u003e\u003cp\u003eThis sensor is a practical match for boats that want depth and water temperature on the NMEA 2000 network without adding a separate temperature probe. It fits well on cruising and racing sailboats where depth is shared across instruments, and on fishing setups where water temperature is tracked alongside depth.\u003c\/p\u003e\u003ch6\u003eMaintenance and care\u003c\/h6\u003e\u003cp\u003eLike any thru-hull sensor, it will read best when the sensing face stays clean. Check it periodically for marine growth, and clean the insert as needed so depth returns stay consistent and temperature responds quickly. Inspect the through-hull area for leaks during routine bilge checks, especially after the first few trips following installation.\u003c\/p\u003e","brand":"B\u0026G","offers":[{"title":"Default Title","offer_id":52269730005173,"sku":"QBP025071","price":419.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1299884_qbp025071.png?v=1771545435","url":"https:\/\/www.qualityboatparts.com\/products\/qbp025071","provider":"Quality Boat Parts","version":"1.0","type":"link"}
