Jack W. Fisher Passes Away at 73
Jack W Fisher, president of JW Fishers Mfg. passed away at home after a brief illness on February 20, 2015. He was 73 years old. The JW Fishers business was started because Fisher, an avid diver, needed an underwater metal detector to use on a salvage project in the mid 1960s. He discovered there was no such device available. Over the next several years he designed and constructed his own underwater metal detector. JW Fishers Mfg. was formed and Jack began building and selling his detectors to other divers.
Side Scan Training for Law Enforcement, Government Agencies
Many public safety dive teams, police and sheriffs departments, and government agencies are acquiring side scan sonar systems to assist in their underwater search and survey operations. Side scan is the ideal tool for these operations because it produces detailed images of the underwater environment regardless of water clarity. In addition, the sonar is able to search large areas quickly, scanning several hundred feet of ocean, lake, or river bottom with each pass of the boat. Side scan can easily locate a variety of targets including sunken boats, submerged vehicles, and drowning victims.
Expanding Underwater Search Capabilities
Over the past year a number of Asian companies and government agencies have acquired underwater search equipment to aid in the location of lost objects and assist in performing survey operations. In China, Guangzhou Advanced Maritime Academy has added a remote operated underwater vehicle (ROV) to their program. Reforms and opening to the outside world have paved the way for development of the country’s shipping industry. The throughput of cargo and containers at China’s ports has been the largest in the world for the past five years with an annual growth rate of 35%.
