I have a plastic dial caliper. An inexpensive item that I have even used underwater, yes salt water, rinse, wipe, air dry.This may not be the most accurate caliper but it serves well and is not inaccurate.

The steel analog vernier caliper that came with my boat when I bought it had a few dark spots of corrosion and it was a bit stuck with not smooth adjustment at all. I gave it some generous wd40 treatment and good exercise and wiped off any excess, and its been working faultlessly ever since.
