This compact nymph net easily fits into most vests and allows you to quickly take nymph samples from the stream, river and creek. Gently kick up a few rocks in a riffle with the nymph net held just downstream. Then lift the net up to view what drifted into it. You'll be amazed at the kinds of aquatic insects you'll find and have never seen on your home waters. Handles are 30cm long. The mesh netting is 30cm x 15cm.
