I've got three Black Walnut boards. One with live edges.
I seen a nail in one. How can I find out if their are any more ?
I need to run them through a planer.

Yup. I built several bookcases out of reclaimed pine and needed to prove the wood before planing. Not the model you linked but there are several that are fairly inexpensive.

We don't know where on the trunk these boards came from ( hi up or lo down ) but the most suspecting area would be 2-6 ft. up from the ground . That's most likely where something was nailed like no -hunting signs , barbed wire or if in someone's yard some sawyers may not want them at all .
As mentioned use the magnet or a metal detector . The sawyer i'm acquainted with , on a log , he looks at the end for black stains when it's still in log form . If so it's chain saw time making fire wood .

Unbeknownst to some people, computer hard drives have a powerful magnet inside. Working in IT I have acquired a few of these magnets from dead hard drives which I use to locate nails in boards. I also screwed a number of them onto a board, attached a handle and used it as a crude metal detector to find dropped screws in my yard after building my deck.

NOTE: These magnets are only found in hard disk drives (HDD), not in solid state drives (SSD).

Of course you could purchase some rare earth magnets from a craft or hobby store or online.

You would think some type of metal detector would be on large commercial plainers.
Most commercial shops won't run suspect or reclaimed wood, or anything from "yard trees." The ones who do work with that type of material will metal detect for hidden items and assume knives will eventually be nicked in the process.
