Drennan Isotopes

Isotopes are ideal for buzzers, bobbins and are powerful enough to make excellent rod tip indicators

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.
