Matrix Precision Sounding Lead comes in a set of 2 and is available in multiple weights. Thanks to its wide base, it does not sink into silt and is designed for ultra-accurate depth measurements. The sounding leads are made of lead-free material and have a slot in the side to keep the line centrally positioned at all times. Bait bands fit through easily and the base of 6mm thick high density foam protects the hook point when you push it in.
