This is 16 inch (40 cm) length of highly visible fluo yellow 8lb monofilament with seven fluo red, one black and seven fluo yellow resin drops spaced in the centre at half inch intervals. It is very sensitive indicator for Czech nymphing, French nymphing and any light nymphing application.
Connect the indicator between your flies and leader using the two microrings supplied with, or tie directly between leader and tippet using the surgeon knot.
At first glance you might wonder how you can possibly see the tiny drops and leader, especially when compared to the bulky foam indicators. But it stands very well in a wide range of conditions from bright sunshine to cloudy overcast skies. The advantage of this exceptional indicator is that it is lightweight, easy to use, very streamline and will not spook the fish.
Drop indicators had been invented by the Czech competition fly fishermen.
