FOR IMMEDIATE RELEASE

December 19, 2006

EdgeTech Announces Price Change for 4200 Series Towfish.

Effective March 1, 2007, the price of the 4200 Series Side Scan towfish will increase; the topside units will remain at their existing prices.

This change in pricing reflects an increase in our cost of components required to build the towfish as well as the new enhanced feature of the 4200 Series, which will now be able to operate dual simultaneous frequencies in both High Definition Mode and High Speed Mode.

Please keep this change in mind when considering purchasing a 4200 Series System in 2007.

Also, our new 4150 Series Side Scan System will be available for order beginning March 1, 2007. The 4150 is a single pulse system (No Multi Pulse) and uses the same tow bodies and electronics as the 4200 Series sonar’s.  The arrays are different and will only be available in the 120/410 kHz configuration initially.

The 4200 and 4150 can use any of the combinations of topside processors.

For any questions regarding this matter or for specific pricing information, please contact Simon Reeves at reeves@edgetech.com or 1-508-356-9704.
