Underwater speed?

[AvionicsMaster1]

How much money do you have? I found this http://www.airmartechnology.com/uplo...res/CS4500.pdf by accident and wonder if it might work. I'm also wondering if you couldn't find one used at a dock or salvager.

The brochure is light on how to hook it up but it would fit your needs almost perfectly. After a quick search I couldn't find anything on the "Airmar paddlewheel format" this is supposed to put out.

That's very interesting.

I wonder what would be involved in rolling your own version. Ultrasonic implies the use of sound, are there new devices out for robotics that could be used for this?

I'm looking at the speeds involved in the specs at it's not NASA-type stuff. Except for the sensitivity of the sensor device, the rest seems within our grasp.
