Overview
Magnesium alloy construction and an 88mm objective lens give the Kowa TSN-88A ZM SET its long-range spotting scope profile, finished in green and weighing about 4.1 pounds.
An 88mm objective is on the larger end for spotting scopes, which typically run from around 60mm up to this size, and it pairs light-gathering ability with a body built from magnesium alloy rather than plastic, adding durability at the cost of extra weight compared with smaller compact scopes. The ZM SET designation suggests it ships as a set, likely scope plus eyepiece, though the listing does not spell out what is included beyond the scope itself.

Who it's for
Birders, hunters, or target shooters doing long-distance glassing who want a large-objective scope in a metal housing are the fit. Anyone wanting the lightest possible pack weight would be better served by a smaller-objective compact scope.
Strengths and trade-offs
Drawn from this product's published specifications.
- Large 88mm objective for long-range glassing
- Durable magnesium alloy construction
- At 4.1 lb, heavier than smaller compact spotting scopes
- Only 1 rating on record
Performance notes
The 88mm objective lens gathers more light than smaller spotting scopes, which helps resolve detail at long range and in lower light. A magnesium alloy housing adds structural durability over plastic-bodied scopes, though it also accounts for most of the 4.1 pound weight.
