No Contact DC Voltage Tester

I have and am familiar with my three no contact AC Volt Testers.
However I do a lot of automotive electrical work and would like to have a DC model.
I do not like punching a hole in the wire insulation to check for voltage.
I have done searches but find none available.
Could someone advise me with a search term for this type tester?

I don't believe they will work with DC as there is no electric field for them to detect. (I think it used to be called flux, but it's been a long time since my Basic Electronics and Electricity classes)

There are signal testers where you place a signal on the wire to enable locating it somewhere else. As for the holes, I had to replace a few wires where holes had been punched, due to the nasty salt they use up here.

I have an ampmeter that just sets over the cable to check the draw of a starter. The old Ford systems had an ampmeter that the wire ran thru a loop,but I have never seen a volt meter that works this way.
