The Furuno M1815 (Model 1815) is a compact 8.4″ color‑LCD marine radar system, pairing a 4 kW X‑band radome (19″) with a rugged, waterproof display suited to small craft and fishing boats. It features automatic gain control and clutter rejection (sea/rain) to produce clear echo images even in dense fog or storms. The radar supports Fast Target Tracking™, allowing manual or automatic acquisition of up to 10 targets, with speed and course vectors shown quickly. With True Trail Mode, moving echoes leave realistic trails, and True View Mode maintains stable echo presentation during maneuvers. It provides flexible range scales from 0.0625 to 36 NM, and a minimum detectable range of 25 m. Power consumption stays low (max ~38 W), operating on 12–24 V DC. The standard kit includes a 15 m antenna cable, a 3.3 m power cable, and a swivel mounting bracket. Environmentally, it’s built for harsh conditions: the antenna tolerates −25°C to +55°C and the display −15°C to +55°C.
