Each marine environment around the globe might have its own specificities regarding composition and geomorphology. For this reason, spearos who want to hunt in a certain region should do their research and gather useful information about the marine environment there. That information will ensure safety and desired results.
The seabed structure is usually mapped out using broadband and/or structure scan side scan – downscan sonar recordings.
I am using SIMRAD NSS12 EVO3 S with AIRMAR broadband transducers and the Active Imaging transducer.
Active Imaging is the latest scanning sonar technology that provides incredibly detailed, high resolution imaging sonar without sacrificing any range.
