I have a Stan Baker Bore Gauge set, and three sets of Plug Gauges to measure shotgun bores. My Stan Baker set has an analog or dial type indicator, but that could easily be swapped out for a digital indicator. If you are otherwise happy with your Skeet's Bore Gauge, simply replacing the dial type indicator might be an option to consider.

I see a pretty wide range of prices for digital indicators, but don't know anything about the quality, accuracy, or reliability of the much cheaper imports.
