Nymph hook setting

Try the following when you are fishing upstream where the fly is drifting towards you and even slightly past you. This can work when you cannot see to nymph all the way. like in pocket water, deep runs, etc.
Simply set the hook every three seconds!
Not the type of hook setting where you rip the fly out of the water or move the nymph a meter or several feet, but a gently quick set, moving the fly not more than 30 centimeters or a foot or so.
Fish like that for a day, with two nymphs, a nymph and strike indicator or what you prefer.
You will be surprised on how many fish you end up catching "extra" that you did not see or feel take.
Don't just try this for five minutes. Try it for an hour or three, or the whole day as a different method and style.
