The DSD-IIIA combines a Superior Optical System (30X magnification/10X zoom) with Manual Precision Control knobs to ensure crystal-clear visibility up to 100 meters. It features High-Resolution 5MP Industrial Imaging to track real-time deviation and includes a Rugged, IP68-rated Stainless Steel Target built to survive high-pressure underground environments.
The DADI DSD-IIIA is a classic, field-proven guidance system designed specifically for pilot tube microtunneling. Trusted by construction teams worldwide, it solves the "blind drilling" problem in horizontal auger boring by combining high-precision optics with industrial imaging.
Unlike fully automated systems, the DSD-IIIA features a robust manual focus design. This gives operators precise physical control over alignment using mechanical knobs, ensuring millimeter-level accuracy even in complex underground environments.
Manual Precision Control
Relies on classic mechanical knobs for Object Image Zoom, Cross Clear, and Object Image Clear adjustments, providing reliable physical feedback to fine-tune focus perfectly.
Superior Optical System
Equipped with a powerful 30X magnification telescope and a 10X optical zoom lens, delivering crystal-clear visibility of the target up to 100 meters away.
High-Resolution Industrial Imaging
Integrated 5MP industrial camera (2592 x 1944) captures every detail of the LED target, displaying real-time deviation on the industrial monitor for immediate correction.
Rugged & Waterproof Target
Includes a waterproof stainless steel LED target (IP68 rated equivalent) capable of withstanding high pressure, ensuring durability in harsh underground conditions.
