Made using tight knit fast-dry mono material, creating a safe-haven for carp, the fishery-approved Baggin' Machine Carp-Sack keepnets have a Six-Plus adjustment angle lock and a thick 10mm polymer bottom ring with stake out D-rings. The thick bottom ring adds strength and weight to the base. These nets are seven-stitched with anti-rot thread for durability and available in 9ft, 10ft and 12ft depths; as well as Silverfish models.
