Tip-Off Indicators are a yarn indicator that is really easy to attach and remove from your leader. Just double over your leader and stick it through the hole on the Tip-Off Indicator. Once it is through the hole, then loop it over the top of the indicator and you are done. To keep the indicator floating high all day long, a good trick is to use a fine-tooth comb and comb floatant into the yarn. Yarn indicators float high and are extremely sensitive for subtle takes. Four indicators per package.
