Dirty Water Test - PowerDolphin Fishing Drone We took the PowerDolphin to a lake with almost no visibility to give it a tough test. You couldn't hardly see these carp with your naked eye and barely with polarising glasses. Amazingly, this tiny area was crawling with massive fish and you'd have no idea unless you could look under the water. Even in the murk, it was easy to spot fish using your phone. They were actually attracted to it!! | Perth Fishing TV
