SIZES: 1g, 1.5g, 2g, 2.5g, 3g, 4g Until now, most anglers have regarded bolo fishing as a style to use in deep water with floats of 3g and above. This new model changes everything as it's designed for use in depths from 5ft to 12ft in any situations where a bulk and single dropper can be used in preference to a strung out shotting pattern.
