There is a selection of
fluorescent green collars to fit a wide range of quiver and rod tips, providing
a neat attachment system. Green is the brightest and, therefore, most effective
of the isotope colours. Visibility is further improved by placing the lights
vertically. With normal line management, this upright position does not
increase the incidence of wrap overs or tangles. With a pair of isotopes
aligned on the rod tip about 25-30cm apart, bites are much easier to read as
the lights move apart.
