Product Overview
Our Submergo™ range of mining & quarrying blast hole dip tapes are a solution for measuring depth of blast holes that has stood the test of time. Attach a weight to the snap ring and lower to measure depth. Our dip tapes are incredibly durable, flexible and lightweight with graduations printed on both sides for ease of use and a means of error reduction. Submergo™ dip tapes are specifically designed for blast hole depth measurement for mining, in all conditions.

Key Features
- Accurate and highly readable markings that are easy to read even when dirty.
- Numbers are graduated from the weight-end of the tape strap (0.0m)
- Swivel at weight end (photo below) to prevent twisting & premature failure of the tape
- Tough, flexible and lightweight with graduations printed on both sides.
- PVC Clear Coating (both sides).
- Not affected by hole deviation, water and dust in-hole.
- Tensile Strength: 100kg.
Trusted by Industry
Submergo™ dip tapes are relied upon across major mining operations including BHP and Rio Tinto for accurate blast‑hole depth measurement. They also serve as a trusted physical reference for validating emerging LIDAR and RADAR hole‑depth systems now being trialed in drill‑and‑blast operations, ensuring electronic readings align with true hole depth during calibration and QA checks.

Surveyor Rope series
These tough fiberglass tapes are an ideal drag chain for rough surveying measurements on the bench. Numbers are graduated from the strap handle upward to the end of the rope. OSR-series are available in 100m & 150m lengths, have metric graduations, and are reputedly more accurate and easier to read than some poly-chain mark-up tapes, at a substantial cost saving.
FEATURES
- Tough, flexible and lightweight
- White with black and red markings, large font – easy to read even when dirty
- PVC Clear Coating (both sides).
- Tensile Strength: 100kg
