Buzzers are not fished enough in this country. They are probably the most versatile pattern as you can fish then at any depth and all year round. Our two favorite methods are on a floating line with a team of nymphs, or fished infront of a damsel on an intermediate line.
This pattern is highly effective and regularly fished in the UK. Typically on a fast sinking line from a boat. Finding the right depth at which to fish one, two or even three buzzers can be the key to success.
