What to know before buying

The listing gives range as 3E+2 millimeters in specifications but describes it as 0-12 inches or 0-300 mm in feature text. Customer feedback also includes reports that it measures only to 11.9 inches, so verify usable reach if measurements near the upper limit matter. Accuracy is a manufacturer claim, not independently established. The listing says waterproof, but provides no rating or test details.
