Vortex Solo 10x25 Monocular

This is not a gun optic and it is not trying to be. It is the thing a marshal, a sniper or anybody running a flank keeps in a chest rig pocket to answer one question: what is actually happening over there. At 4.4 inches long and under six ounces it costs you nothing to carry, which is the only reason a spotting optic ever gets used rather than left in the car.

Ten times magnification handheld is honest about its limits. Braced against a tree or a wall you will read a treeline cleanly; waving it one-handed while out of breath you will not. The close focus distance of 16.4 feet is the specification worth noticing for our use — it means the optic still focuses on something only five metres away, which a pair of full-size binoculars often will not, and that matters when you are looking through a gap at a bunker rather than across a valley.

The body is rubber armoured for grip and for surviving being dropped on hard standing, and the housing is nitrogen purged and O-ring sealed, so British weather and the temperature swing between a cold morning and a warm safe zone will not fog the inside of the glass. Like every Vortex optic it carries the unconditional lifetime warranty, which on something small enough to lose or sit on is more relevant than it sounds.

Specifications

Good to know

Can I mount it on a rifle? No. There is no rail interface and no reticle. It is a handheld observation optic.

Monocular or binocular? A monocular is half the bulk and half the weight and fits a pouch. Binoculars are easier on the eyes over long periods. For intermittent use in the field the monocular wins on carry alone.

Is 10x usable without a tripod? Braced, yes. Freehand you will see image shake, which is true of any 10x optic and not a fault.
