I use a magnetic release when I use a net and it works quite well for me. There is another reason that I like it though. It really comes in handy when I acidently drop a small fly while tying it on or taking it off at the back of my truck. If I am unable to find it visually I just drag the part that dangles off the end of the net through the grass and leaves and sometimes I am be able to pick up a fly that would normally be lost. Phil
