Description

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.

  • Maximum 200J per shot
  • Rugged mechanical design with weight kept to a minimum
  • Provides stable pulse shape clarity with minimum reverberation
  • Supplied as an individual product or with CAT100 or CAT200 catamaran
  • Supplied with RMK connectors as standard
  • Ideal for small craft and coastal surveys

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.

  • Maximum 350J per shot
  • Unique control of driven plate and precise pulse shape
  • Special cooling system for reliability
  • Supplied as an individual product or with CAT200 catamaran
  • Replaceable components for easy field maintenance
  • Supplied with RMK connectors as standard
  • Ideal for nearshore and shallow water surveys (up to 120m depth) depending on geology
