Allswimming submerged fishing (1000 fishing method, alllayer fishing method) is a fishing method that can expect unbeatable high fishing results if you master it, but if the conditions are bad, it will become a difficult fishing method. I tried to summarize the points to be careful when the conditions are bad. This is not a knowhow to solve everything, but I would be happy if you could refer to it even a little. (I can't explain line mending. It's a necessary technique, but...)
