BSS+ Sub Bottom Profiler

BSS+ Sub Bottom Profiler

SDI’s BSS+ is ideal for surveying in shallow water, harbors, and waterways and pre- and post-dredge applications.  It is a simple-to-operate, complete hydrographic survey and sub-bottom profiling system contained in a single portable splash proof unit. The system includes an Intelligent Depth Sounder (IDS), a true digital sub-bottom profiling capability, a differential GPS receiver (DGPS), a reference receiver, a navigation computer, a TFT color display, survey software and rapid data playback and review software.  IDS is a full survey grade depth sounder that digitizes the echo to 16-bit resolution and stores the full digital record on hard disk. IDS provides playback with high resolution and detail.

65,536 shades of gray are digitized versus a maximum of 16 shades typical of paper records. The depth resolution is maintained regardless of the depth range. Navigation data and all other collection parameters are saved with all depth soundings. Positions, events and operator annotations are exchanged between HYPACK and SDIDEPTH programs.  DEPTHPIC and SDIDEPTH software provide convenient replay and reprocessing of hydrographic data without hand digitizing or scaling of position.  Post-processing with DEPTHPIC saves XYZ data in ASCII text format compatible with HYPACK, SURFER, AutoCAD, ArcView and GIS programs for contouring and TIN mapping.

The portable waterproof case and operation from a 12-volt car battery makes the BSS+ ideal for small boat operations. With the BSS+, a battery and a boat, you are ready to begin surveying. All survey and post-processing software is included.  The 200 kHz Intelligent Depth Sounder provides the latest technology in high resolution and accuracy with the added convenience of “paperless” electronic recording.  The sub-bottom profiling capability adds up to 4 additional operating frequencies to the 200 kHz IDS depth sounder.

Up to five frequencies, ranging from 3.5kHz to 200 kHz, can be utilized to provide depth and fine resolution sub-bottom profiling. Sub-bottom profiling in less than 1 foot of water depth is possible.

SDI’s hardened computers include armored display windows, marine grade aluminum display housings and non-corrosive impact resistant plastic cases with stainless steel hardware.  Display controls and hinges are o-ring sealed and connectors are waterproof or splash resistant. This computer can be upgraded in the future unlike most laptops.
