About this deal

He says the best way to learn to evaluate fish size is to look at the fish through the scope, study its form while considering the depth and distance away, and then catch it and weigh it. Over time, you’ll develop your eye.

When the fish gets it I set the hook with my hand,” Dobson says. “Then I can drop the Flogger, because it floats, then grab the rod and reel it in.” Barham EG (May 1963).

Get even closer to the underwater world by building a bathyscope or underwater periscope with these how-to guides. Stay safe!

Following the successful bathyscaphe testing, Jacques Piccard and his father spent the early 1960s focusing on designing and building mesoscaphes, meant for exploring the middle depths of the ocean. Jacques tested his first mesoscaphe, named the Auguste Piccard, in 1964.Under the time constraints of a tournament practice and competition day, it’s important to have an efficient search system, particularly if incorporating a bathyscope into the process. Among my favourite mysteries of the natural world is Bathysphaera intacta, a 6ft fish said to resemble a large barracuda. The new species was supposedly spotted by the explorer and naturalist William Beebe in 1932 at a depth of 640 metres (2100 ft) off the coast of Nonsuch Island in the Bermuda archipelago. We have no photograph of the fish and the only image that exists was drawn by Else Bostelmann, a German-born American artist, who accompanied Beebe on his expedition. Bostelmann never descended into the ocean’s depths; her drawings, based on Beebe’s descriptions, are 20th-century marine equivalents of Dürer’s Rhinoceros, creatures that the artist had never seen first-hand. Jacques Piccard worked closely with Lt. Don Walsh on increasing the diving capabilities of the bathyscaphe, and their work paid huge dividends. To make a bathyscope, follow this simple tutorial most kids can do on their own (or with a little assistance from an adult). Materials to Make a Bathyscope:

You can buy a bathyscope, but we think it’s much more fun to make your own. It’s also a lot less expensive because it’s free! The onboard systems indicated a depth of 37,800ft (11,521m) but this was later corrected to 35,813ft (10,916 m) by taking into account variations arising from salinity and temperature. Later and more accurate measurements made in 1995 have found the Challenger Deep to be slightly shallower at 35,798ft (10,911m).Artist's rendering of the bathyscaphe Trieste, the vehicle that carried Swiss scientist Jacques Piccard and U.S. Navy Lieutenant Don Walsh to the bottom of the Challenger Deep in the Mariana Trench on January 23, 1960. The Trieste descended to a depth of 10,916 metres (35,814 feet), the deepest dive on record. (more) Stretch the clear plastic over the end of the bathyscope and secure in place with the rubber band. Make sure it's stretched tight so that you can see through it clearly. Cut both ends of your chosen tub or bottle to make the main body of the bathyscope. If you've got a pipe, then both ends will already be open. If you've chosen a tub or bottle, you will need to remove the bottom. Make sure the end you will use to view has no sharp edges as it will be close to your face. In 1960 Trieste, carrying Piccard's son Jacques Piccard and Don Walsh, reached the deepest known point on the Earth's surface, the Challenger Deep, in the Mariana Trench in the Pacific Ocean. [1] Make sure you stay safe - don't lean over the edge too far and make sure where you're sitting or standing is firm ground.
