Sound Source, Boomers
Model
The AA251, deployed on either a robust CAT100 or CAT200 catamaran, is ideal for inshore surveys from small craft, including high-resolution sediment analysis.
The AA301 is designed for higher power applications and can also be used as a variable frequency boomer when combined with a CSP energy source. The lengthening of the pulse width ensures even greater penetration whist maintaining a high-quality single pulse.
Key Features
- Stable pulse shape clarity with minimum reverberation
- Rugged mechanical design with weight kept to a minimum
- Supplied as individual product, or with a catamaran
- Supplied with RMK connectors and locking collars as standard
- AA251 forms part of the Inshore Boomer System, ideal for coastal surveys
- AA301 ideal for nearshore and shallow water surveys (up to 120m) depending on geology
Applications
- Nearshore and shallow water survey
- Hydrographic sediment investigation
- Cable and pipeline route survey
