His float tube was outfitted with a Lowrance HDS 7 GEM3 fish finder and TotalScan Transducer – a unit capable of producing an extremely detailed high definition 3D portrayal of the bottom with its StructureScan® technology.
The angler, Paul Zoch, posted the screenshots online, where others confirmed the object looked to be a body. While not convinced himself, Zoch contacted authorities to share his findings.
A San Diego Public Utilities Dive Team conducted a search on Wednesday morning, and was unable to locate a body. They called off the search, concluding that the image portrayed a pile of logs, and not human remains.
The Otay Lakes area is no stranger to underwater discoveries. The larger Lower Otay Lake was the sight of one of the most amazing discoveries made with a consumer fish finder, when Duane Johnson, a local bass angler discovered what appeared to be a plane on his Humminbird fish finder. Their discovery turned out to be a long lost Helldiver plane which crashed into Lower Otay in 1945.
