"In the battle between man and fish, technology has swayed things to humans' favor," said David LeClair at Gizmag. The FishHunter ($199) uses sonar to help anglers locate potential underwater prey, floats on the surface like a bobber, and links to a smartphone via Bluetooth. The gadget's portability opens up the use of sonar to shore fishermen, and the app adds some tricks of its own. It stores location data to make it easier to return to a lucky fishing hole, and it links to Facebook and other social networks to help you share snapshots of your big catches.
