I use the net below which is the Frabill 3672.
It is cheap, rugged, and very light-weight. A no-brainer at $20.
Its gape is 13″ x 18″, meaning it easily can land a good-sized fish. Moreover, the net is made from rubber and is significantly more C&R-friendly than my old nylon net. It’s also much easier to ease out flies that become entangled within it.
As I’ve written before, I also use the Orvis Net Retractor. No fumbling with magnets, etc. It smoothly retracts when I’m done with the net. I also can unclip easily the net from it. In that way, I can wedge the net in the water among some rocks to let a fish recover at its own pace. It makes it easy to take photographs, whilst also keeping the fish in the water to reduce its stress. I don’t handle much the fish with my hands.
A trout usually recovers in a few minutes. Then, I tilt the net, and the fish nearly always sprints away.
So, there you go. A good net for C&R and at a bargain price, IMO.
