Chapter 218 - 150: Super Dogfish
As for deeper locations, Lin Yang had not considered them yet, because the measured depth at this spot was only about twenty to thirty meters.
Since the big fish had appeared on the surface, there were chances in the upper layers as well.
After setting the depths for the two fish, Lin Yang adjusted the unloading force of the fishing device again, making sure it was set so that a fish weighing several dozen pounds could not pull it free, but a bigger fish, such as one weighing over a hundred pounds, could still get hooked when it bit.
Seeing him expertly set up the fishing device, Han Li asked curiously, "Mr. Lin Yang, what’s the principle behind this fishing device? It seems that if a big fish is caught, wouldn’t it just drag the device away? Do we need to tie extra ropes to secure it?"
Lin Yang shook his head with a smile, "No need, the two hooks are tied separately, connected to two independent fishing lines, each 50 meters long, with a force unloading device and an automatic reeling function."
"That still doesn’t sound right, floating on the water, the automatic reeling can’t possibly contend with a hundred-pound fish, can it?" Han Li asked, not waiting for him to finish.
Lin Yang smiled and pointed to a circle on the side of the device, "See this yellow-marked circle here? Inside it is a reaction device. If the force exerted by the fish exceeds the set unloading force too much, it will activate the reaction device.
Then it will pop out an airbag the size of a life jacket, similar to the airbag in a car. The huge buoyancy combined with the sturdy unloading device will stabilize the big fish. Eventually, when the fish exhausts its energy after pulling the unloading device with the connected airbag, it will float to the surface. This method could even be used to catch whales weighing several tons in the sea, let alone a mere several hundred-pound big fish."
"Ah? Whales? Isn’t that a bit exaggerated?" Hearing Lin Yang’s description, Han Li involuntarily covered her mouth, her eyes filled with disbelief.
