I never tried a digital fillet gage, I didn't even know they made them. But being in the machining business, I use digital tools often. I have alot of guys on my crew who use only digital, and guys who won't touch them. I personally never cared for digital. I still like the dials and vernier scales myself. (just something about them). As with many battery powered tools, if the battery fails, you have nothing. I always feel that there is an element of uncertainty with those things.
Kind of like a flashlight. Dead batteries, dead flashlight. A good argument for using candles. Oops, they run out of wax after a few hours.
Technology definitely has it's limitations and it is imperative to recognize those limitations.
The digital fillet gage has limitation without a doubt. The pieces have to be perpendicular to each other and the gage is really simply measuring the throat dimension. Then again, I can see where it may be useful for measuring the convexity of the fillet weld and verifying it meets the limitations of D1.1.

"I can see where it may be useful for measuring the convexity of the fillet weld and verifying it meets the limitations of D1.1. "
Can you elaborate, the only thing I have found is a contour gage for checking convexity. I think it could be useful for checking reinforcement but a bridge cam gage or reinforcement gage will operate with a pocketful of dead batteries!
Just curious on this, do the guys also know how to read a vernier scale? I find that more and more people don't know how.
