[PSUBS-MAILIST] building sonar transducer

[via Personal_Submersibles]

Hello all,


I'm looking at building a sonar transducer to measure bottom depth for a small ROV project and would like to ask how I should go about pressure-proof/waterproof the system.  


I'm looking at building it with a Arduino Uno Rev 3 microcontroller and a Ultrasonic sensor module.
