I have been doing research the past week in search of a good monocular for bowhunting. I hunt light and only carry a small fanny pack with me so binoculars are really not suited for me. I just bought a monocular from Amazon for under 50.00 that is absolutely fantastic. I cannot believe the quality that I got for this low price. I got a Wingspan Outdoorsman 8x42 and could not be happier. The image is bright,crisp, and clear. It has very easy one hand operation and is fairly compact. It is about 6" long and weighs around 11oz.
At the exact same time, I bought 2 Vortex monoculars to compare and keep the best one. The Wingspan won hands down. It really wasn't even close and the Vortex cost 100.00 or more. Needless to say, I returned the Vortex and kept the Wingspan. BTW, the Vortex were a 8x36 Tactical and the 8x36 Solo.
If anyone is thinking about trying a monocular, I think you will be very pleasantly surprised by the Wingspan. I highly recommend it and the one hand operation is a breeze, which is good for bowhunting.
