Wide Angle Sonar Seafloor Profiler (WASSP) is a combination of technologies packaged into a uniquely versatile, powerful and cost-effective electronic fishing, marine surveying and scientific research tool. WASSP is available in a number of versions : 160Khz Fishing, 80Khz Fishing, 160Khz Survey. Fishing versions utilise 224 seperate beams to give 120degree coverage. Survey version utilises 224 equiangular or equidistant beams to give variable resolution based on application.

  • Chirp technology with variable bandwidth and frequency agile transceiver (can cover 10Khz - 500Khz)

  • High Detail Images

  • Real Time Map generation

  • Beam stabilisation

  • Variable beam width

  • 5 Beam Sounder

  • Advanced DSP, eliminates noise to/from other acoustic equipment

  • Dynamic Depth and Seafloor coverage

  • Advanced Fish Histogram – Target fish species

WASSP Fishing version offers 224 beams@136-184kHz with 48Khz bandwidth from 2m <200m. Up to 16Hz ping rate, with variable beam width, multiple power levels optimised depth, depth to coverage ratio 1:3.4 , and is compatible with wide range of 3rd party sensors. Compatible with Maxsea, QINSY, HyPack, Sodena other 3rd party software. OLEX interface pending.



2D & 3D view of a harbour survey using OLEX with the WASSP Fishing version. This is a 'real life' example of WASSP in use; here the harbour wall, pylons, seafloor and navigation chart can all be seen clearly. This system accounts for tide, heave, pitch, & roll in real time eliminating the need for post-processing.

2D & 3D view of a harbour survey using OLEX with the WASSP Fishing version. The seafloor on both the 2D and 3D windows are showing backscatter (hardness), as well as seafloor contours, navigation chart, and an along-track profile of the seafloor. Hardness can be customised by the user in real time to allow small changes (1%) to be easily seen.
