Highlights:
Real‑Time 3D Imaging & Smart Detection: Pioneering the industry, Invenio Pro delivers full real‑time 3D visuals of underground targets—showing shape, depth, size, and metal type—instead of just beeps or target IDs
AI‑Driven Target Recognition: Powered by an artificial neural network, it intelligently interprets buried items and ground anomalies (like cavities or voids), offering smarter detection and fewer false alarms.
Versatile Multi‑Frequency Support: Invenio Pro operates on 5 kHz, 14 kHz, and 20 kHz, allowing fine‑tuning to different metal types and soil conditions. Ideal across various scenarios, from deep treasure hunts to relic recovery.
Comprehensive Coil Set & Seamless Tracking: The Pro pack includes three waterproof DD coils (11″×7″, 15.5″×14″, 22″×19″) plus the IPTU sensor for precise positional tracking and mapping of detected targets.
Rugged Design & Long Battery Life: Built for extended field use with a large 7″ backlit TFT display, waterproof coils, LED flashlight, vibration alerts and up to ~9 hrs run time via dual Li‑ion batteries (system & spare included) .
