The bottom line is there are individuals that do the work, study the fishes patterns, place habitat, and grow into truly skilled fishermen that, with a little luck will reap the rewards for their efforts. While there are others, whom with today’s technology, scan the waters with there eyes, binoculars, side imaging, or by whatever means they can employ to poach fish they would NEVER be able to catch on their own. Advanced technology in sonar will do nothing but make the poor, lazy fishermen more capable, which in turn will rob the workers for there efforts. Reading this thread, you can easily determine which side each responder belongs.
