With a native \u003cstrong\u003eSeaTalkng output\u003c\/strong\u003e, it connects directly to your onboard network and delivers accurate depth and temperature data to all compatible connected displays — no additional converters or interfaces required.\u003c\/p\u003e\n\n\u003ch2\u003eSeaTalkng Network Integration\u003c\/h2\u003e\n\u003cp\u003eThe DT800 outputs depth and temperature data directly over SeaTalkng, making it plug-and-play compatible with Raymarine’s network ecosystem. Data is available simultaneously on all connected displays and instruments — including \u003ca href=\"\/products\/raymarine-axiom-7-multitouch-chartplotter-realvision-3d-ready-north-america-ray-e70634-00-102\"\u003eAxiom+ chartplotters\u003c\/a\u003e and the \u003ca href=\"\/products\/raymarine-i70s-multifunction-colour-display-ray-e70327\"\u003ei70s multifunction instrument\u003c\/a\u003e.

The 235 kHz frequency is specifically chosen to prevent interference with other onboard depth sounders or fishfinders operating at standard 50\/200 kHz frequencies.\u003c\/p\u003e\n\n\u003ch2\u003eThrough-Hull Installation\u003c\/h2\u003e\n\u003cp\u003eThe 2-inch high-strength plastic housing is suitable for fiberglass or metal hulls. The 0° internal element is designed for flat (horizontal) mounting positions, making it ideal for hulls where a level installation surface is available. A retractable housing with integrated water valve allows for easy maintenance and transducer removal without hauling the vessel.\u003c\/p\u003e\n\n\u003ch2\u003eCable \u0026amp; Connectivity\u003c\/h2\u003e\n\u003cp\u003eIncludes a 20 ft (6 m) interconnect cable with SeaTalkng connector, ready to plug directly into a SeaTalkng backbone or spur.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch2\u003eParts Desk Insights\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBest Use Case:\u003c\/strong\u003e Ideal for sailboats and powerboats running a Raymarine SeaTalkng network where a dedicated, high-accuracy through-hull depth and temperature source is needed. Particularly well-suited for vessels with an existing Axiom chartplotter or i70s instrument where network calibration can be performed without additional tools.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrough-Hull vs. Transom Mount:\u003c\/strong\u003e This is a through-hull unit requiring a 2-inch hull penetration. It is not a transom-mount or in-hull transducer.
