The two boomer plates, the AA200 and AA300, produce a sharp, repeatable "industry standard" single pulse. Both models are field proven and differ in detail specification. The Model AA200 is the ‘small format’ transducer which can be towed on either the CAT100 or CAT200 surface tow vehicles. It is
ideal for inshore surveys for high resolution sediment analysis with the CSP-L energy source or as a higher penetration device

The CSP-D is a seismic energy source for boomer and sparker applications which has been developed from the proven CSP1500
and CSP2200 versions.Uprated to 2400 Joules and with a higher rated thyristor ‘switch’ the CSP-D sets the new industry standard.

What makes the Geo-Spark Concept different? That is its designed for very fast, extremely powerful, NEGATIVE, High Voltage discharge of 5.6kV up to 20kA.  It is this electric "punch" which makes the difference in the powerful acoustic pulse that provides the resolution and penetration.
Also, by using the Geo-Spark power supplies, the electrode tip-wear is reduced to pratically zero. That means no more electrode consumables and no more interruptions in the survey work. Which in turn means that you are actually saving a lot of time and money!
