Fact #1. Humans have been fishing for at least 40,000 years. Analysis of the remains of an eastern Asian man who died between 39,000 and 42,000 years ago indicates a substantial part of his diet was freshwater fish. This suggests that he regularly engaged in some kind of fishing practice.
Fact #2. At first, fish were pulled from the water by hand, or harpooned. Then, between 4,000 and 8,000 years ago, Neolithic men developed fishing methods that are still in use today. For instance, Native Americans along the California coast deployed gorge hooks attached to line tackle.
Fact #3. The earliest ancestor of today's underwater fishing camera dates back to 1845. An English invetor discovered he could progressively record images of the instruments at an observatory. He did this by slowly pulling a photosensitive surface past an opening in his camera. His technique was used to record variations in scientific instruments in observatories worldwide for more than a century.
Fact #4. The first underwater camera was invented by a French scientist. It took 30 minutes to expose a single frame. The scientist made the first underwater photo in 1893. Similar to today's underwater fishing cameras, his camera featured a water-tight housing and a compressible air bladder. Modern units use digital technology to transmit images to a display in the boat. Many models feature filters and image processing to clarify underwater images.
Fact #5. Using an underwater fishing camera can be a great deal of fun. However, it's important to avoid being distracted by the display when navigating a boat. It's also important to wear a life jacket. Even if the boat isn't yours, you should insist that every passenger wears a life jacket. It's also imperative that you prepare before going out on a trip. This includes charging phones and packing water, flashlights, and maps.
