MODEL COMPARISON
Put two views side by side.
Compare the exact specifications and compromises. A blank in the evidence stays unknown, rather than becoming a guessed advantage.

| Main tradeoff | An 11-hour battery rating does not change the detector’s detail limits. TOPDON’s own identification claim is much shorter than its detection claim, which matters when you need to name a distant animal. | The Pro’s ten-hour runtime rating is shorter than TS004’s eleven-hour figure. Its 650-yard detection claim must not be read as identification at that distance; TOPDON lists identification separately. |
* Weight may be listed with or without a battery; check the exact model analysis. Battery life is a rated claim under manufacturer conditions, not measured endurance. Highlighting marks a difference, not a winner.
A larger screen is not a higher-resolution thermal detector. Compare native sensor resolution, lens and scene width together. Model guides link to the original specifications.
