In this case, the string is an expendable material that must be replaced in the process of operation. Based on the design and operational features of the trimmer for grass, manufacturers equip their products with the most diverse types of heads. from simple hand reels to complex automatic reels.

The importance of proper reeling

To prevent this from happening, it is necessary to set up all fishing equipment in advance. One of the most important stages of preparation for fishing is the correct winding of the line on the bobbin of the fishing reel. Failure to follow the basic rules threatens the poor angler with tangles and breaks in the line, and fishing instead of pleasure will be a test for the nervous system.

Therefore, before you start, it is necessary to consider a few tips from experienced fishermen on how to lay the line on the bobbin. This is a fairly simple procedure that even a beginner can cope with.
