What can an angler do to enhance the vision, to spot the indicator on the water with ease?
I carry two different types of polarized sunglasses with me on the water at all times. My first pair has an amber colored lens and my second pair is a dark grey lens. During low light level conditions I will wear the amber colored lens. This enhances the color of the yellow or green indicators and makes it easy to see thru my eyes. When we have partly to mostly sunny skies I will wear the dark grey sunglasses to cut the glare from the water. It is necessary for me to use a bright red or bright orange indicator during these conditions so I can see my indicator and to tell what’s happening with my presentation.
