Weatherproof Transducers
These work well, after I had continued to increase their transmit input voltage. They are very inefficient as you might suspect seeing that there is aluminum on their face rather than an acoustically-transparent screen. So they required around 90VDC through a MOSFET amp to operate well. These are marked T and R but I believe they are otherwise identical.
