Quickly and easily get an accurate measurement of your catch with Frabill's Grip 'N Check measurement system. Simply grab hold of the fish's lip and slide it into the Grip 'N Check's funnel arms. Once the fish is guided into the measuring position, use the curved thumb press to hold the fish securely in place and get an accurate measurement. An easy-to-read, highlighted box lets you determine whether the fish is the minimum "keeper" length. If the fish's tail doesn't reach the box, simply turn the Grip 'N Check on end and let the fish slip back into the water. High-impact polycarbonate construction rinses clean for years of easy and accurate measurements. Extra-long design lets you measure fish up to 13". Wide entry allows fish to slide in easily and raised grip lines prevent slippage for increased control. Flattened nose surface ensures more precise measurement. The gap between flat nose and sides allows for nose adjustment for more precise measurement. Right- or left-handed guides give you plenty of room to position the fish.
