New products available.
Hitting water acoustically with 42.8khz, Keely style.
========================================
I notice that one can buy two ultrasound transmitters, pitched at 40khz, and a driving board for around £35.
The snag is that one needs to examine the board, see what it takes to adjust the existing fixed frequency.
