The patented Measure Net is the only landing net that allows the angler to catch, measure and release a fish without touching it. Simply land the fish in the net and add the numbers at the head and the tail to get the total length. "Catch, Measure, Release" The Measure Net is made of strong aluminum tubing with a durable rubber handle that allows the net to float for a little while until the handle fills with water giving you time to retrieve it. Of course it is always best to tether your net - just in case!. The netting is very soft fish friendly nylon.
