Sub-bottom profiling

The majority of problems are due to generator/installation issues or cable and connector failures. When contacting us please provide us with as much information as possible, including model number and serial numbers.

Please remember that lethal, high voltages are used in the equipment so no internal repairs must be undertaken. Only applied acoustics trained engineers should attempt a repair.

Returning equipment

In order to return goods to us a Return Materials Authorisation (RMA) number is required.

Please visit our RMA request page where you can find further information and a form which can be completed to begin the process.

Regional centres

For repairs and technical assistance, our service centres in Houston and Singapore may be the first point of contact.

The businesses have vast experience of using applied acoustics’ equipment and carry some stock of spares. They receive regular training and may also have some equipment available for hire.
