Equipment Resources

The Micro-Modem has been in development for several years, now. As a result, many new equipment designs have been created: transducers, shallow water enclosures, deep water enclosures, power amps, matched to most commercially available transducers, accessory electronics and transudcers.

This equipment is documented, and much of that documentation is presented here. If you cannot find the information you need using the links to the left, please contact us, and we will be happy to assist you.
