The Rozemeijer Compact Safe Mat & Weigh Sling 60cm is the perfect mat for the trolling perch / zander angler. The perch angler from the boat hunting for that one monster perch can also use this mat perfectly. Once caught, you unhook, measure and weigh the perch with the same mat! After this you roll the mat up again, clip it to your backpack, or store it in a (small) compartment of your boat. Now you will never again have an excuse not to have a unhooking mat with you.
