Key Benefits and Applications

• Sharper identification in challenging conditions — The high‑resolution sensor and ZEISS image processing reveal fine structures on animals and terrain, improving target recognition in fog, drizzle or complex backgrounds.
• Confidence at distance — A practical detection range up to 1,845 m helps you pick up heat signatures early, giving you more time to assess and act responsibly.
• Fast target acquisition — Movement Alert and Hot Tracking draw your eye to the hottest and moving subjects, speeding up scanning across open fields, forest edges or mountainous terrain.
• Optimised viewing for any scene — Switch between Universal, Detect and Fog observation modes and 8 colour palettes to maximise contrast whether you are navigating dense vegetation or open ground.
• Stable framing while zooming — Picture‑in‑Picture keeps a magnified view anchored within the wide scene, maintaining context and reducing re‑acquisition time when subjects move.
• Long, comfortable sessions — Up to 7 hours of runtime, smart standby and a balanced, ergonomic housing reduce fatigue during night surveys, wildlife counts or search tasks.
• Seamless recording and sharing — Onboard memory and wireless connectivity make it easy to document observations and synchronise with the ZEISS Hunting App for logs and collaboration.
