I am researching the possibilities to build a sounder. It is possible to build a depth sounder using $20 ultrasonic cleaning transducers. The electronics are not too complicated. These transducers only 28-40khz so they would have deep range possible up to 100 meters deep.
Eventually it should be possible to mount two transducers in the boat to also measure waterspeed and temperature.
Has anyone interest in doing this?
