Nikon Monarch vs. Vortex Viper

The best companion for your hunting escapades would be the best quality equipment that dominate the optical market. This time round, let us find the best pair of binoculars for your hunting escapades.

Without the best pair of binoculars in your hunting gear, your hunting activity may be such a bore and a challenge because majority of the time you will not be able to identify your target. I genuinely don’t think that any hunter would want to miss out on target acquisition when hunting just because their target got out of sight a little bit too fast or just because they couldn’t see clearly.

To avoid such issues when hunting, you may need to purchase high-end binoculars. I would suggest the Nikon Monarch and the Vortex Viper binoculars for your hunting gear, particularly the 8×42 models. In this review, we will look at the Nikon Monarch 5, the Nikon Monarch 7 and the Vortex Viper HD. The table below summarizes their top features and their main differences.
