If you've ever been stumped by a rising trout because you couldn't figure out what it was feeding on, you need the Quick-Seine. It attaches easily to your net handle and instantly turns that landing net into a seine, so you can quickly determine what insects are present in the drift and narrow down what that picky fish might be eating. The regular size fits net hoops up to 9" x 13", and the large size fits nets up to 10.5" x 18.5".
