Overview
The Barska CO10998 is a spotting scope with a 75mm objective lens and manual focus, listed at 1 lb. It carries a 3.8 rating across 141 reviews.
A 75mm objective lens is on the larger end for spotting scopes, generally aimed at longer-distance viewing where more light gathering helps, though manual focus means adjustments are hands-on rather than motorized. Its 3.8 rating sits below the Swarovski spotting scope also in this set, worth noting for anyone comparing across brands.

- 1 lb listed weight
- 3.8 rating from 141 reviews
Who it's for
Works well for buyers wanting a larger-objective spotting scope for long-range viewing such as range work or nature observation, comfortable with manual focus control. Not the pick for anyone chasing the highest rating in this category, given the comparatively lower score.
Strengths and trade-offs
Drawn from this product's published specifications.
- 75mm objective lens for longer-range viewing
- Manual focus keeps the mechanism simple
- 3.8 rating trails other optics in this catalog
- Listed 1 lb weight seems light for a 75mm scope and should be confirmed before buying
Performance notes
The 75mm objective lens is sized to gather more light over long distances than smaller spotting scopes, which typically helps image brightness at range. Manual focus puts adjustment entirely in the user's hands rather than relying on any motorized or electronic assist.
