What length of seven star drift would work well for a 13 meter rod

If you are fishing in shallower waters, such as lakes and reservoirs, you can choose a shorter seven star drift, such as 3-4 meters. This will allow you to get a better grip on the sensitivity of the rod and spot the fish bite signals in time. If you are in deeper waters, such as rivers and seas, you can choose a longer seven-star drift, such as 4-5 meters. This will make the seven-star drift floating on the water surface more obvious and improve the chances of fish biting.
