C 3 Simrad PI Catch monitoring system / Portable hydrophone Paravane arrangement The portable hydrophone available with the PI system has a broad coverage area. For this reason, its orientation with regard to the sensors is not that critical. The hydrophone weighs approximately 700 grams (in salt water) and can be mounted on a towed paravane. This solution is suitable for smaller vessels, and it is made up of a little paravane and a weight. The arrangement is designed to draw the portable hydrophone down to approximate five to ten meters depth when towed at a moderate speed (maximum of three knots). The kit contains all necessary parts (except one!) as described in the following illustration. Order number: KIT-207284 4 851-164730 / Rev.
