Gen 3 is Here: The Ultimate Upgrade to the Scout 137 Drone System

June 17th, 2025

3 minutes read

The Scout 137 Gen 3 isn’t just an upgrade; it’s a strategic response to the harsh realities of industrial inspection. Built to operate in GPS-denied, hazardous, and confined environments, this third-generation system integrates survey-grade LiDAR, ultrasonic thickness measurement (UTM) with surface preparation, optical zoom, and unlimited tethered flight into one intelligent, rugged platform. Every enhancement is rooted in field feedback, driving real gains in safety, data quality and operational efficiency.

What’s New and Why It Matters?

Inspecting cargo tanks, wind turbines, ship hulls, hydropower shafts, and more? the Scout 137 Gen 3 brings major advancements in close-range stability, precision measurement, and visual accessibility.

Let’s break down the most impactful innovations:

Scout Portal Auto-upload resume, context-rich POIs 3D cloud, annotation tools Enhanced reliability and usability Upgraded

The Gen 3 Advantage in Action

In live environments, the Gen 3 has consistently demonstrated its agility in rusted tanks, control in steel corridors and clarity in dim, congested spaces. Its sensor fusion, combining 3D LiDAR, optical zoom, and ultrasonic data, means fewer flights, more reliable measurements, and reduced reliance on human entry. This translates into fewer shutdowns, lower inspection costs, and higher data confidence across asset management teams.

 

The introduction of automated launch/recovery and gas detection also brings safer workflows, particularly in environments where even entry-level mistakes can have catastrophic consequences.

 

With all mission data funneled through the Scout Portal, users gain instant access to synchronized 3D point clouds, annotated imagery, and UTM records, all spatially aligned for intuitive analysis. This accelerates reporting, simplifies compliance, and enables easy benchmarking against historical inspections.

 

From structural engineers to safety managers, teams can now collaborate in real-time, flag critical issues faster, and prioritize repairs with confidence.

Precision Meets Protection in Close-Contact UT Inspections

The UTM Payload is engineered for precision ultrasonic thickness measurements directly from the drone platform, no manual intervention required. Its patent-pending docking head combines surface preparation and ultrasonic inspection into a single, efficient motion.

 

This integration ensures optimal contact and clean A-scan results across a wide range of materials and surface conditions.

Real-time parameter control allows the system to dynamically adjust to surface variations, while the servo-controlled magnetic release ensures a clean, stress-free disengagement. Unlike traditional systems that rely on brute force to separate from magnetic contact, this smart release mechanism protects the drone’s airframe and enhances flight safety by avoiding unnecessary mechanical strain or frame distortion during detachment.

 

With its close-contact capabilities and safety-first design, the UTM Payload sets a new standard for automated ultrasonic testing in hard-to-reach or hazardous environments.
