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 requiring high-resolution sediment analysis, particularly in nearshore and shallow water survey operations and hydrographic sediment investigations.
The AA301 is designed for high-power applications and has the extra advantage of use as a variable frequency boomer when paired with an energy source that allows wide-ranging pulse widths not formerly available. The lengthening of the pulse width ensures even greater penetration whilst maintaining a high-quality single pulse, making it well-suited for cable and pipeline route surveys as well as broader coastal surveys.
