For a number of years I have been using The Measure Net system. Why, you might ask? Well the quality and function of the item is exactly what you would expect. In my opinion far better than the price paid. What is most important is the fact that I know exactly the size of my fish without removal from the water and with the shortest amount of time. I just received my third and will put it in action first thing in the morning. It's Landlocked Salmon time here in New England.Here is the link to a wonderful product. The Measure Net
