Leupold BX-4 Pro Guide HD 10×42 Binoculars Review


This past fall, I was fortunate enough to hunt in several states ranging from the cattail sloughs of North Dakota, to the Sandhills in western Nebraska, to the agricultural rich states of Iowa and Wisconsin. It gave me the opportunity to really put these optics through the ringer in a variety of different locations and in a variety of different elements. In this review, we are going to take a good look at the Leupold BX-4 Pro Guide HD 10×42 binoculars. First, let’s check out the specs and features of these optics.

The Look and Feel of the Leupold BX-4 Pro Guide HD Binoculars

Leupold BX-4 Pro Guide HD 10x42 BinocularsUpon first glance, the new Sitka Subalpine camouflage jumps out at you. I was excited to see that Leupold made that happen. This model is very compact in size for the highly respected 10×42 magnification. Lack of size, means lack of weight, which translates to forgetting that you are wearing them when they are strapped to your chest, which is awesome.

The ergonomic design made using these binoculars a pleasure. The solid open bridge construction is complimented a slip free finish ensuring that you’ll maintain your grip and steadiness in any environment.

The HD clarity is excellent, and even in low light. I have used other optics that match this type of clarity, but none of them match this clarity in low light. The light gathering capability is unlike any pair of optics I’ve ever seen for under $1,000.

The focus knob is very user friendly. It moves very smooth, with little friction, and perfectly placed for comfortable adjustments. The diopter adjustment is utilized by pulling the focus knob cap toward you, exposing the dial indicator. Rotating eye cups provide plenty of range for eye relief.

These optics exceeded my expectations. The stand out feature was definitely the clarity in low light conditions. I can’t stress enough how strong they are in that particular category.

Nothing is perfect, and these are no different. I did find a couple of things to that could be improved. I was surprised that Leupold didn’t include a provision to tether the eyecup covers. There was a strap in the box but it did not suffice. In my opinion, a quality product like this should come equipped. Another thing that I noticed is that the manual doesn’t explain how to adjust the diopter for this new model. I found instruction for older models, but no updates by Leupold for the newer models in the Pro Guide HD series.
