Start with the decision holding up your purchase
If you already have a spending limit, open the guide for that budget first. The under-$500 shortlist compares entry-level viewing and power arrangements; the under-$1,000 guide explores two observation scenarios; the under-$2,000 guide asks what a more expensive detector or integrated rangefinder actually adds. The broader budget guide helps when you have not yet decided where to stop spending. Its job is to identify the first worthwhile upgrade, not encourage you to climb every price tier.
For a shortlist organized around the outing, choose compact carry, wildlife observation, hunting observation, or long-range viewing. These guides explain different compromises, so start with the situation you encounter most often. Already considering two exact models? Read their individual analyses and use the comparison table to check where the specifications diverge. Before ordering, the recording, battery-care and helmet-mounting guides help expose additional requirements that a headline sensor resolution cannot answer. The best-thermal-monocular guide brings several of these choices together when you need a starting shortlist.
