Constructed from advanced Macromolecular Polyester Carbon Fiber & Kevlar, it offers unparalleled durability and stability. With a massive 50kg payload capacity, intelligent obstacle avoidance, and a powerful dual-battery system, the DUSV 8 is the ultimate multi-purpose platform for professional hydrographic surveying, environmental monitoring, and search & rescue operations.

This intelligent GNSS receiver is powered by a Linux + ARM Cortex-A7 platform and distinguishes itself with a Non-Contact Laser Measurement module, allowing precise, prism-free capture of hard-to-reach points. It integrates an IMU to eliminate "fly points" through real-time tilt compensation and utilizes an ultra-wide-angle camera for intuitive AR Real-Time Stakeout. Housed in a rugged Magnesium Alloy body with IP68 protection, it supports comprehensive connectivity (4G/WiFi/Radio) and ensures long-term endurance for professional surveying.

The DSZ32 Automatic Level combines high-performance optics with ergonomic design, featuring 32x magnification and 1.0mm leveling accuracy. It utilizes a precise X-shaped wire suspension air-damping compensator with a range of ≥±15' to maintain stability in vibrating environments. Distinguished by its ultra-short 0.4m minimum focus range, it excels in confined spaces. The unit is designed with integrated handrails for safe handling and carries an IP54 rating for water and dust resistance, ensuring reliability in the field.

The DSZ32B Automatic Level combines high precision with a powerful 32x magnification telescope, achieving a standard deviation of just 1.0mm (1km double-run leveling). It features a stable X-shaped wire suspension air-damping compensator with a range of ≥±15', ensuring reliable results even in unstable conditions. Designed for versatility, it offers an ultra-short minimum focus of 0.5m for work in confined spaces. With an IP54 rating for protection against high-pressure water jets, the DSZ32B is built to withstand harsh field environments.
