Wow, you folks must be fishing in the land of OZ. Sure you don't need an indicator when you are standing next to the run your fishing and if the water is relatively clear and the lighting is right and the wind is not blowing and....... When I'm nymphing I typically have to deal with rain, sleet/snow, howling winds, a canoe, pontoon or river john spinning wildly out of control, one hand on an oar, paddle or tiller one hand on my rod flipping, rolling flicking my fly out, poor lighting, glasses that are full of water drop/fish slime and frozen fingers that hardly grip enough to mend. I use a bobber and a big bobber at that. Maybe one of these days I'll be on the river when everything is perfect but it hasn't happened yet.
