Premier Locslide Waggler No2
These locslide floats are almost unbeatable for leger or feeder fishing in slow rivers or still waters. The floats will lock to the right depth on their own allowing you to fish those previously un-fishable swims.
These self locking floats can be fished at any depth in still or very slow moving waters. They come with full instructions for use. It's a well tried and tested method.
