Eyes on the water: How local mariners can accurately detect a submerged human proxy in shallow nearshore coastal water with modern recreational fish finders. [PDF]
J Forensic SciAbstract It has recently been demonstrated that modern recreational fish finders with high‐frequency (800 kHz) Sidescan transducers can detect submerged human bodies. This ubiquitous technology is widely used on the water and has the potential to be utilized for the rapid detection of submerged decedents in any waterbody.
