HMS-620 Bubble Gun Seismic Systems
Portable, Low Frequency, Acoustic Sub - Bottom Seismic Systems
The HMS-620 Bubble GunTM systems use low-frequency acoustic signals to provide superior signal penetration vertically through coarse sand, gravel tills, and other difficult-to-penetrate sediments. HMS-620 Single Source Ideal for Small Boat or Inland Surveys HMS-620D Dual Source Higher Source Level, Greater Penetration HMS-620LF Low Frequency Source Wide 20 – 1700 Hz Energy Spectrum Ideal for Multi-Channel Reflection Surveys

HMS-620LF Low Frequency Bubble GunTM Source Vehicle
Single and Dual Source Systems do not need heavy handling or deployment equipment
Wide-band 70 - 1700Hz pulse provides bottom penetration through many sediment types
LF System Source Bandwidth 20Hz – 1700Hz
Very stable and repeatable source pulse without the need for external timing controllers
Rugged, lightweight transducer platform provides stable operation in adverse sea-state conditions
o Electromagnetic acoustic source; Contained Air Volume (no air compressor needed)
Minimal Electric Power Requirements
o Selectable 110 or 220 VAC source of less than 1 KWatt for Single Source, or 2 KWatt for Dual or LF Source
Flexible portable transceiver unit optimizes system for a wide range of sediments
o Low-noise pre-amp with high/low pass filters and gain control
o User-selectable trigger or external trigger
o Multiple Sources can be synchronized to a common trigger without need for external timing control
o Repeatable Shot-to-Shot Phase and Amplitude Wavelet Correlation > 0.96
Oil-filled single channel hydrophone streamer cable incorporates a 7-meter multi-element active section
o 35-meter deactivation switches on each hydrophone element enable exportation outside of USA
Compatible with industry-standard data acquisition software & multi-channel streamers
