The Preston Offbox Clicker Counter is a must have item for the match angler who wants to keep track of how many fish he or she has caught or who wants to keep track of the catch weight, to avoid exceeding the catch limit per keepnet. The operation is super simple, you press the big button on top to add caught fish, while the display can be reset via the dial on the side of the unit. The Clicker Counter comes with an OffBox pivot point including insert, meaning it will fit the legs of virtually all seat boxes and footplates on the market. Included insets: 23mm OffBox, 25mm Round, 30mm Round.
