Once the exclusive preserve of commercial fisherman, recreational anglers are now investigating the deep reefs that lie either side of the continental shelf drop off, which are home to deepwater ooglies like blueeye trevalla, gemfish, hapuka, bass groper and cod. Winding a massive sinker or single big fish up out of 70 to 150 fathoms of water requires a lot of effort, but the Shimano Dendou-Maru electric overhead reel makes it easy.
