I purchased the Yukon Tracker 3x42 expecting a larger version of the 2x24 models. It's not. Everytime you need to focus you must do each lens separately. The lens covers do not fold back and stay attached and the case. The case is too small for this model and deforms the rear lens shield. They must use the same case for all the Tracker models. I would stick with the smaller Tracker models or look at a different brand.
Pros: Decent night vision for Gen1.
Cons: Basically two monoculars with one power source.
