A boomer plate, or ‘boomer’, emits acoustic impulses or pressure waves, known as a transmission pulse, from its floating position on the sea surface through the seawater to the seabed. The two models of boomer, the AA251 and AA301, produce a sharp, repeatable single pulse and are deployed on a robust catamaran.

The AA251 is the small format transducer that can be towed on either the CAT100 or CAT200 surface tow vehicle. It is ideal for inshore surveys for high-resolution sediment analysis.

\n\n
The AA301 is designed for high power applications and has the extra advantage of use as a variable frequency boomer when used with the energy source that allows wide-ranging pulse widths not formerly available. The lengthening of the pulse width ensures even greater penetration whist maintaining a high-quality single pulse.
