Overview
A high-power straight-body spotting scope from Leupold, the 177598 pairs a 20-60x zoom eyepiece with an 85mm objective lens for reaching long-range targets. The aluminum housing and straight eyepiece configuration are built for shooters who glass from a fixed position rather than on the move.
The listing marks this unit as the straight variant (177598), distinct from Leupold's angled 177599 counterpart. Beyond magnification and objective size, the available specs are limited to a stated 91.7 foot field of view and an aluminum build; no waterproofing, coating or included-accessory details are listed.
- 20-60x zoom on an 85mm objective lens
- Straight eyepiece body (177598)
- Aluminum housing
- Field of view listed at 91.7 feet
Who it's for
Suits hunters and target shooters who set up on a bench, tripod, or blind and look straight through the eyepiece rather than down at an angle. Less suited to spotters who prefer glassing from a low or seated position, where an angled body is typically easier on the neck.
Strengths and trade-offs
Drawn from this product's published specifications.
- Large 85mm objective for a brighter image at distance
- Wide 20-60x zoom range in one scope
- Straight eyepiece suits bench or tripod glassing
- No waterproof or fogproof rating listed
- No case, tripod, or accessory info given in the specs
Performance notes
The 85mm objective is sized to pull in more light than the smaller 60mm and 40mm scopes in this lineup, which matters most at the top of the 20-60x zoom range where image brightness typically drops off on any zoom spotter. The listed 91.7 foot field of view gives a sense of how much ground is visible at the wide end of that range.
