How big of a fish can you catch with 7 kilograms of drum wheel unloading force

How big of a fish can you catch with 7 kilograms of drum wheel unloading? You can catch dozens of pounds of fish, no problem. We need to know the drum wheel relief. He is to counteract the pull of the fish. So how big a fish, how much tension and in how deep the water, this is the need for anglers to have a common sense judgment. It's not necessarily true that a 7kg fish can exert a 7kg pulling force. This also depends on the depth of the water where he is. The deeper the water the stronger the pull of the fish. The unloading force of the drum wheel is 7 kilograms. It can actually counteract about 1.5~2 times the pulling force. As long as it is matched with the strength of the fishing line, there is no problem.
