Harbor Freight’s 6″ digital caliper is so cheap, it must be a great deal, right?
Well, we’ve found that its battery life is incredibly short, so if you only use it occasionally you’ll often find it dead. And the accuracy isn’t up to snuff for demanding jobs — testing it against some gage blocks showed some ranges with no error but others with an error upwards of .04″!
On the plus side, you don’t have to worry about dropping them as you would with one of the $100+ calipers from Mitutoyo.
Ultimately I prefer the Mitutoyo for regular use, but what do you think: Hot or Not? Let us know in comments.
