It is a low-profile, retractable thru-hull sensor with SeaTalkng output, so depth and water temperature data can be shared directly with compatible Raymarine network displays.\u003c\/p\u003e\u003cp\u003eThis transducer operates at 235 kHz, which helps it run alongside common 50\/200 kHz fishfinder transducers without interference. It has 100 W output and is rated for depth readings from 0.5 m to 180 m, giving it useful range for shallow water, coastal cruising, fishing, and general navigation.\u003c\/p\u003e\u003cp\u003eThe DT800 uses a 2-inch plastic thru-hull housing suitable for fiberglass or metal hulls. Its retractable housing includes a water valve for service access, and the 6 m cable with SeaTalkng connector supports a clean network installation without a separate transducer pod.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eSmart depth and temperature transducer for Raymarine instrument and chartplotter systems.\u003c\/li\u003e\n\u003cli\u003eSeaTalkng output connects directly to compatible Raymarine marine networks.\u003c\/li\u003e\n\u003cli\u003e235 kHz operating frequency helps avoid interference with common 50\/200 kHz fishfinder transducers on board.\u003c\/li\u003e\n\u003cli\u003e100 W output with depth readings from 0.5 m to 180 m.\u003c\/li\u003e\n\u003cli\u003eLow-profile, retractable thru-hull housing with water valve for easier maintenance.\u003c\/li\u003e\n\u003cli\u003e2-inch plastic housing suitable for fiberglass or metal hulls.\u003c\/li\u003e\n\u003cli\u003eAvailable with 0° or 12° internal offset angle to suit different mounting locations and hull shapes.\u003c\/li\u003e\n\u003cli\u003e6 m interconnect cable with SeaTalkng connector included with the transducer.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eVariants\u003c\/h6\u003e\u003cp\u003eThe DT800 is offered in two offset-angle configurations. Both versions are for depth and temperature measurement, connect through SeaTalkng, and share the same general thru-hull smart transducer format.\u003c\/p\u003e\u003cp\u003eThe offset angle is the main difference between the variants. The 0° version is for flat or horizontal mounting positions, while the 12° version helps compensate for deadrise where the transducer is installed on an angled hull section.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eA22112: Offset angle 12°. This version uses a 12° tilted internal element for installations where the hull angle needs compensation so the beam is aimed more directly downward.\u003c\/li\u003e\n\u003cli\u003eA22165: Offset angle 0°. This version uses a 0° internal element for flat or horizontal mounting positions where no offset correction is needed.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eThe DT800 is intended for thru-hull installation, so the mounting location should be chosen carefully with access inside the hull for the housing, cable routing, and future service. The 2-inch housing and retractable insert make it a practical choice for boats where the sensor may need to be cleaned or checked without replacing the full fitting.\u003c\/p\u003e\u003cp\u003eCalibration is handled from a connected Raymarine Axiom chartplotter or i70s instrument. After installation, depth offset and temperature checks should be completed at the display so the numbers shown at the helm match the way the boat is used.\u003c\/p\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eThis transducer is a good match for boats already using Raymarine SeaTalkng instruments or chartplotters and needing dependable depth and water temperature data on the network. It is useful for cruising boats, fishing boats, and sailboats where a low-profile thru-hull installation is preferred over a larger fairing block.\u003c\/p\u003e\u003cp\u003eHull angle matters when selecting the variant. A flat mounting area generally suits the 0° model, while an angled hull section may call for the 12° model to keep the acoustic beam pointed closer to straight down.\u003c\/p\u003e","brand":"Raymarine","offers":[{"title":"12°","offer_id":52581981290677,"sku":"QBP668826-V1","price":399.0,"currency_code":"USD","in_stock":true},{"title":"0°","offer_id":52581981323445,"sku":"QBP668826-V2","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1335161_qbp668826.webp?v=1780202022","url":"https:\/\/www.qualityboatparts.com\/products\/qbp668826","provider":"Quality Boat Parts","version":"1.0","type":"link"}
