Review on Keson DG10018 Fiberglass Depth Gauge with Graduations by Sam Chandler

I recently purchased a fiberglass measuring tool with depth graduations from Industrial and Scientific category, and based on my observations, it's a reliable and useful measuring tool for my projects. The measurements are accurate, and the fiberglass material appears to be durable, able to withstand regular use in any weather conditions. My only concern is the lack of additional measurements like the metric system, which could limit its usefulness among an international audience.
