    I happened to be talking to a Russian guy that informed me that they have discovered you can use the JSN-SR04T ultrasonic sensor underwater as a Depth sounder, its popular on their bait boats. it works essentially the same as the classic SR04 ultrasonic sensor, all you need to do is change your code to compensate for the faster speed of sound to get it working accurately.

    Looks very good.

    Do you have any more information? Links etc?

    (i wonder how they re-programmed it?)

    Wow! Add some depth charge throwers and you're all set hunting U boats in the pond.

    I am not sure how they have programmed the controllers, but the sensor works the same as the sr04 sensor and there are many many instructional pages on how to use them with arduino, the only modification you need to do is change the constant for the speed of sound in water.
