Speed performance has been taken to the next level with the ST900 Speed/Temperature sensor. Featuring the new Gen2 Paddlewheel, the ST900 outperforms all other paddlewheel sensors for responsive startup and linearity. The Gen2 Paddlewheel begins delivering accurate speed reporting as low as 0.3 knots and maintains smooth speed output through 45 knots.
Available with a plastic or bronze transducer housing, they sit nearly flush with the boat's hull and minimize drag with only 5mm (3/16") extending outside the hull. The housing has a valve assembly that helps to minimize water ingress in the bilge when the sensor is removed for routine maintenance of the paddlewheel.
Features:
Speed and fast-response water temperature sensor
Analog output for use with Raymarine instruments like i40, i50, iTC-5, and legacy systems
Retractable for easy maintenance
ST900 transducer core is retrofittable into existing Airmar P120 and B120 transducer housings

Where Have You Been All My Boating Life?
What a great little piece of tech - I don't know how we got by without it in the past. No more guessing how full the holding tank is or having to clean icky tank senders. This little bluetooth RADAR sending unit mounts on top of the tank and connects wirelessly to our Victron Cerbo.
Setup is super easy, push the button on the unit so it can calibrate to the tank then enable bluetooth and set up your rank dimensions on your Cerbo. It's as easy as that.
We've had it installed and running for about two weeks now and couldn't be more pleased (We like it enough that I ordered a second one for our water tank.)
