Here at marinews.com we are committed to the very best of boating equipment testing. That is why we use Marine Publications articles as we know each sounder, fishfinder, GPS, radio etc., has been physically taken to sea and tested while in operation on the water. These articles are sourced from the pages of Trailerboat Fisherman and Australian Boating. The guys at Marine Publications have a reputation of telling it how it is and therefore you the end user can make your purchasing choice with a far greater deal of confidence.
