GeoPulse 2 offers digital Chirp and Ricker waveforms, in addition to pinger functionality. These new waveforms offer enhanced resolution and advantages depending on the geo- logical conditions and water depth. Despite these upgrades,

GeoPulse 2 is designed to be a simple drop-in replacement –

GeoAcoustics users don’t need to replace their existing GeoPulse cabling or transducer, and it’s compatible with systems like Chesapeake
