I would highly recommend that all anglers have a good pair of polarized sunglasses with them at all times. Polarized sunglasses help to cut the glare of the water and help you see deeper into the water. This enhanced vision can help you to spot laydowns, weeds, and ledges and can allow you to see things you have not noticed before. This will give you an advantage when you are out on the water and will help you locate prime places to cast your lures.
