Binoculars or monocular? Choosing a TacticalEye optic

The 8x40 binoculars and the 10x42 monocular share the same tough build. Which one belongs in your pack depends on how you look.

TacticalEye optics in rugged country

Both TacticalEye optics are built the same way: an aluminium and rubber body, fully multi-coated lenses and prisms, sealed against dust and sand, fog-proof and packed in a hard-shell case. The difference is how they ask you to look.

The 8x40 binoculars

Two eyes are more relaxed than one. For long sessions glassing a ridgeline, following movement or watching wildlife, the 8x40 binoculars are the easier choice. The BAK4 Porro prism gives a bright, wide image and a strong sense of depth, and the 8x magnification is steady enough to hold by hand.

  • 8x magnification, 40mm objective lenses
  • BAK4 Porro prism, fully multi-coated
  • Fold-down eyecups for use with glasses
  • Net weight around 800g

The 10x42 monocular

When weight and speed matter more than comfort, the monocular earns its place. At around 0.66lb it rides in a chest pocket or on a MOLLE strap and comes up to the eye in a second. The 10x magnification brings distant detail closer for a quick check before you move on.

  • 10x magnification, 42mm objective lens
  • Roof prism with fully multi-coated optics
  • Compact, one-handed use
  • Net weight around 0.66lb

Which one?

If you spend more time watching than walking, take the binoculars. If you spend more time walking than watching, take the monocular. Plenty of people carry both: the binoculars in the pack for the long look from camp, the monocular on the strap for everything in between.

Look after the glass

Blow grit off the lenses before you wipe them, use a soft lens cloth rather than a shirt cuff, and keep the lens covers on when the optic is not in use. Stored in the hard case, either one will last for years.
