Detailed Description
The boomer plate produces a repeatable pulse in the 1-6kHz frequency range using an electrodynamic transducer that can be powered by a capacitor discharge system. It has a penetration on the order of 150 m (depending on sediment type) and provides a balance between resolution and penetration. It can be used in freshwater lakes where a sparker would not be suitable.
