ShockWatch Tube vs ShockWatch 2 – Complete Comparison Guide

ShockWatch® Tube vs ShockWatch® 2 – Complete Comparison Guide

ShockWatch® Tube and ShockWatch® 2 are both single-use impact indicators from SpotSee, but they are built on different technologies and suit different types of shipments. This guide explains how they work, where they are used, and how to choose the right option for your supply chain.

What Is ShockWatch® Tube?

ShockWatch® Tube is a current SpotSee product that uses a glass tube filled with a red dye. When an impact above the selected G-level occurs, the dye travels into the activation chamber, providing a clear visual signal of mishandling.

• Glass tube design: Proven, reliable mechanical activation.
• Multiple sensitivities: Available from 10G to 100G.
• Highly visible: Bright activation chamber for easy inspection.
• Compatible housings: Can be used in Clip, MiniClip, and Flex formats.

ShockWatch Tube is widely used in industrial equipment, heavy components, and legacy systems where glass indicators have been standard for years.

What Is ShockWatch® 2?

ShockWatch® 2 is SpotSee's modern polymer-based impact indicator. It provides a tamperproof, field-armable design with a bright red activation window. It is the most widely used impact indicator in the SpotSee range.

• Polymer housing: More durable and tamper-resistant than glass.
• Clear activation window: Turns bright red when triggered.
• Serialized options: Supports traceability and accountability.
• Available in QR and RFID variants: Enables digital event logging.

ShockWatch 2 is ideal for electronics, medical devices, aerospace components, and high-value shipments where accountability is essential.

Key Differences at a Glance

• Construction: Tube uses a glass vial; ShockWatch 2 uses a polymer housing.
• Tamper resistance: ShockWatch 2 is more tamperproof.
• Digital options: Only ShockWatch 2 offers QR and RFID variants.
• Mounting: Tube can be used in Clip, MiniClip, and Flex housings.
• Use cases: Tube suits legacy/industrial; ShockWatch 2 suits modern, high-value shipments.

Which One Should You Choose?

Choose ShockWatch Tube if you need compatibility with legacy systems, Clip/MiniClip/Flex housings, or industrial environments where glass indicators are still standard.

Choose ShockWatch 2 if you want a modern, tamperproof indicator with optional digital traceability (QR or RFID) and a cleaner, more durable design.

For shipments requiring both impact and tilt monitoring, consider pairing either indicator with TiltWatch® XTR or TiltWatch® Plus.
