If you're tired of cleaning paddlewheel sensors and want rock-solid readings from 0.1 to 50 knots, this is your transducer.\u003c\/p\u003e\n\u003cp\u003eThe UDST800 packs three functions into a single low-profile thru-hull with zero maintenance. Ultrasonic sensing means no paddlewheel to snag or foul—just clean, adaptive data that adjusts automatically to your boat speed, water depth, and clarity. It's the difference between guessing your speed and knowing it precisely, especially when you're running hard or fishing shallow.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eUltrasonic Speed, Depth, and Temperature\u003c\/strong\u003e — no moving parts, no paddlewheel maintenance — you'll spend your time fishing instead of scrubbing sensors.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdaptive Smart Sensor Technology\u003c\/strong\u003e — automatically adjusts filtering and sampling to match your boat speed, water depth, and clarity — accurate readings whether you're trolling at 1 knot or running 40 knots to the next bite.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle Low-Profile Thru-Hull Housing\u003c\/strong\u003e — fits existing Airmar P617V, B617V, or SS617V holes without extra installation work — retrofit into bronze or stainless steel housings if you upgrade later.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e235 kHz Frequency\u003c\/strong\u003e — prevents interference with other sonars on your boat — especially important if you're running multiple echo sounders or a full suite of electronics.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRetractable Plastic Insert with Water Valve\u003c\/strong\u003e — protects the sensor when hauled out and simplifies servicing — one less thing to worry about between trips.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e10 Data Updates Per Second\u003c\/strong\u003e — fastest refresh rate in its class — critical for accurate speed and temperature data when conditions change fast.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNMEA 2000 Output\u003c\/strong\u003e — integrates seamlessly into networked systems — one cable connection to your entire electronics backbone.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecs \u0026amp; What's Included\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eCompatibility:\u003c\/strong\u003e This transducer retrofits into Airmar P617V, B617V, or SS617V housings. It outputs NMEA 2000 and requires a compatible network (most modern integrated systems support this standard). Operates on 9–16 VDC. Not sure if this works with your setup?
