I am looking for a better set of calipers, but precise options are limited and expensive. like I said, in a pickle.

FYI, Mitutoyo calipers have an accuracy tolerance of ±.001in as well.
If you want to measure to the ten-thousandths, you'll need a micrometer and I suggest getting a digital one.
You can also verify the accuracy of the calipers you already own by using a gauge block.
