If you don't deal with measurements on a daily basis, I would suggest getting a cheap rangefinder.
The best tool for both fog and measuring distance is radar. If I had a forced choice between a chartplotter and radar, I would choose radar.
I have used radar to anchor in fog. I just pick a spot with sufficient distance to the other vessels. Very slick.
When underway in restricted visibility radar will pick up other vessels and objects, a chartplotter will not.
