How to accurately find the bottom of wild fishing?

If you go fishing in strange waters, you can look for the bottom first and then shallow, which means pulling the buoy up a little first (drawing). If the buoy is all on the water, it means that the water depth here is not as deep as you adjust it, and then pull the buoy down, if the buoy is standing at a 45-degree angle and a half. This shows that your depth is still a little deep. Keep pulling down the buoy. If the buoy only appears on the water, it will find the bottom. No matter how many times you adjust it, keep adjusting the appearance of the buoy on the water, and you will find the bottom.
