Customer Story: From Pilodyn to V-Meter – Taking Timber Testing Underwater

When a long-time industry tool like the Pilodyn wood density tester is discontinued, many are left wondering what to use next. That was the case for one of our recent customers, who needed to assess the condition of submerged wooden pylons and asked the question:

“Is there a replacement for the Pilodyn—and can it work underwater?”

Our answer: Yes. Meet the V-Meter MK IV.

Designed for non-destructive ultrasonic testing, the V-Meter MK IV has become a trusted choice for assessing the internal condition and density of timber. But where it really stands out is in environments the Pilodyn could never reach—underwater.

By pairing the V-Meter MK IV with underwater ultrasonic transducers, the customer was able to successfully test submerged timber structures without removing or damaging them. Accurate velocity measurements were captured directly on-site, even below the waterline.

Why They Chose the V-Meter MK IV:

  • A reliable and modern alternative to the discontinued Pilodyn

  • Capable of testing both dry and submerged timber

  • Delivers real-time data on material condition and integrity

  • Portable and rugged for field use in marine, construction, and forestry

  • Also supports testing of concrete and composite materials

This project demonstrated that the V-Meter MK IV doesn't just replace the Pilodyn—it outperforms it. From jetty pylons to bridge supports, it’s the tool for professionals who need to go beneath the surface—literally and technically.

Searching for a Pilodyn replacement?

The V-Meter MK IV is ready—on land or underwater.
