TE425S vs TE419S vs TE210S – Full Specifications, Features & Performance
The new-generation Guide TE Series thermal monoculars (TE425S, TE419S, TE210S) represent a major leap forward in compact thermal imaging technology, now built on Guide Sensmart’s ApexVision S1 architecture with ultra-sensitive sub-15mK NETD performance (model-dependent within the broader ecosystem).
This new platform replaces the older TE generation and delivers:
Designed for Australian hunters, farmers, and security users, the new TE Series is now positioned as a premium compact thermal monocular range, not an entry-level system.
