Nikon Monarch 5 Binoculars Review

The Nikon Monarch 5 Binoculars feature top-of-the-line and extra-low dispersion glass lenses. The low dispersion glass lenses of these binoculars provide a more natural and brighter view.

The lenses being multicoated and the prisms being dielectric multilayered, work together and provide a higher light transmission and create a high-contrast clear view. The Monarch 5 also features amazing waterproof and fog proof characteristics due to the Nitrogen-filled and O-ring sealed.

The binoculars work well even in low light and provide a bright and clear view, especially for the price that you pay for them. The eyecups of these binoculars have multiple relief positions and the focus knob and diopter adjustment have perfect stiffness that does not allow them to move unnecessarily, providing a great experience for casual users, or those not looking to spend a small fortune on optics.

Vortex Diamondback HD Review

Vortex Diamondbacks are 10x magnification binoculars. These binoculars are easy and fast to get on target. The light weight magnesium chassis and the rubber armor exterior provides durability and secure hold on the binoculars. The resolution of these binoculars is aided by Vortex’s excellent HD optical system.

The anti-reflective lens coatings and the multi-layered prism coatings are a win-win for hunters, providing excellent visibility in multiple lighting conditions, and the center focus wheel of the binoculars adjusts the focus of both the barrels of the binoculars.

For water and fog proof performance the binoculars have Argon gas-purged and O-ring sealed, and they come with a Glasspak Harness to carry them, which is nice.

Hunters who own the Vortex Diamondback HD love its light-gathering feature and the clarity of the view it provides. The higher magnification, wide FOV, and affordable price of these binoculars have satisfied many hunters who are on a strict budget for gear.

  • Higher magnification
  • Nice, wide, and immersive FOV
  • Sharp image view
  • Accurate colors
  • Rich details in the center of the view
  • Warmer color spectrum (good for hunting)
  • It Shows rich browns, yellows, and greens
  • Perfect alignment that feels good to the eyes
  • Immerse view even in dim light
  • Slightly more contrast
  • Good for hunting


  • Not so deep focused
  • Colors not quite accurate but in contrast
  • A little heavy


In this comparison, there is no clear winner. Both binoculars are honestly excellent, though depending on your activity, you may choose one or the other. Based on our previous experience with the Vortex products, they’re great in difficult lighting conditions, which is a big plus for hunters. They also have rich colors and a wide FOV, which is equally important.

But, if you need a pair of binoculars for birding then the Nikon Monarch 5 is a better option because of the universally sharp FOV, broad and nice focus depth, and the focus that remains intact even when the dial is rotated. Birding requires more details than hunting, and Vortex’s best features may be lost on birders who are out in ideal conditions rather than hunting at dusk or dawn in low light.
