iGaging Depth Gauge Digital Electronic Indicator 0-22in - Precise

In this review the iGaging Depth Gauge proved to be a practical, no-nonsense tool for machinists, woodworkers and inspection technicians who need repeatable depth measurements over a long range. The single biggest reason to buy is its combination of long 0 to 22in reach with a high-resolution electronic indicator that reads to 0.0005in, making it useful when both range and precision matter. The review focuses on real-world use: setup, readability, attachments, and where the gauge fits into a small shop or inspection bench.

Key Features

• Range 0 to 22in: The included six extension rods expand the base travel so the gauge can measure deep pockets and stepped features without improvisation.
• High resolution: The electronic indicator offers 0.0005in resolution, which helps pick up fine differences when comparing depths or setting tools.
• Multiple units: The display supports inch, metric and fractions, so operators can work in the format their process requires without conversion errors.
• Two-position base: The indicator can be mounted on the center or side of the 4in base to suit different setups and improve stability on flat surfaces.
• Ten attachments included: With six extension rods and four feeler points, the gauge is ready for common measuring tasks and hard-to-reach spots out of the box.

Who It's For

The gauge is best for machinists, quality inspectors and serious hobbyists who need a long measuring reach plus fine resolution for depth, sink and pocket checks. Its combination of a 22in maximum range and a 0.0005in indicator resolution makes it suitable for bench inspection work and setup tasks where accuracy matters.

Those who should look elsewhere include users who need ruggedized, waterproof instruments for harsh shop-floor use or a dedicated short-travel micrometer alternative; this product is a precision measuring gauge with an electronic indicator, not a heavy-duty contact depth micrometer replacement.

Pros & Cons

Pros

• Good value for the measured range and accuracy thanks to long extension rods and a fine 0.0005in resolution indicator.
• Clear digital readout with inch, metric and fraction displays improves readability and reduces conversion mistakes.
• Reasonable build quality and a two-position base give stable setup options for different surfaces and measurement methods.

Cons

• The electronic indicator travel is 0-1in, so the system relies on extension rods for long reach rather than a single continuous spindle length.
• Not designed as a rugged, sealed instrument for wet or very dirty environments; it is best used on a bench or in controlled shop conditions.
