I think a lot of guys can see beds, but they can’t see if the fish is actually in the bed,” Dobson says, referring specifically to smallmouths. “Up here in the northern lakes in Michigan, a lot of fish will spawn deeper than 8 feet. If it’s flat calm and sunny and the water is clear, you can see the bed, you can see the fish on it and you can judge the size of the fish. When you get beds deeper than that, say up to 12 or 15 feet, or you get ripples or drops of rain, it’s much harder to see them and judge their size. When you drop that bathyscope in the water it basically takes the glare and ripple off the surface. Once you get a trained eye and you do it enough, you can kind of gauge the size of the fish.” A plastic tub/bottle/pipe - the taller this bit is, the further away from the water your face will be when you're viewing the underwater world - and the wider the base, the more you'll see in one go. A traffic cone shape is ideal; a bottle will work well too. The float is filled with gasoline because it is readily available, buoyant, and, for all practical purposes, incompressible. The incompressibility of the gasoline means the tanks can be very lightly constructed, since the pressure inside and outside the tanks equalises, eliminating any differential. By contrast, the crew cabin must withstand a huge pressure differential and is massively built. Buoyancy at the surface can be trimmed easily by replacing gasoline with water, which is denser.

[3] This put to rest the question of whether or not there was life at such a depth in the complete absence of light.

A slightly more complicated construction, a periscope will allow you to see (or photograph) underwater at a 90° angle, as if you were snorkelling - whilst staying dry! What you'll need: 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] 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.

The most simple device to construct to look underwater, you can build a bathyscope almost entirely out of found materials. Use it to look into shallow bits of water with easy access and cut out the surface glare. What you'll need: Jacques Piccard worked closely with Lt. Don Walsh on increasing the diving capabilities of the bathyscaphe, and their work paid huge dividends. To find deep smallmouth beds is the most popular reason why the bathyscope is used by anglers, and if you’re content to sight fish smallies without one, you might be missing out.

You can easily make a simple bathyscope with materials you likely already have at home. At RGK, we’re big fans of reusing and repurposing materials you already have to eliminate waste and save money. a b c d Brand, V (1977). "Submersibles – Manned and Unmanned".

I had two areas [at Champlain] that had 15 to 20 beds that I found when it was rough and the waves were crashing in there that I could see moderately well,” Dobson recalls. “And then we used the Flogger to gauge them.” A sheet of glass or plexiglass to cover one end of the pipe. You could buy a small picture frame and remove the glass - but be careful of any sharp edges.Their work would result in the first manned journey to the deepest part of the ocean, some seven miles beneath the surface using a bathyscaphe. That’s 7,000 feet deeper than Mount Everest is tall. Development Of The Trieste
