The Centium Retainer/Weigh Sling from 30Plus is excellently designed for anglers who specifically target really big carp and catfish. It is large, very robust, fish-friendly and has four high buoyancy floats. It has two rigid 12mm fibre support rods at the top with soft EVA carry handles. The material is waterproof and easy wipe clean while retaining soft-touch properties for fish protection. The base and four side areas are meshed to ensure oxygenation of the fish and the secure clip-lock adjustable closures along with press stud closure options on the side zips provide total fish security. The webbing carry/weigh handles have steel lined holes to allow a retaining cord to be added without fear of it detaching. Designed in consultation with Team 30Plus over a six month period this Centium product really does set the standards for others to try and follow.
