Well, with Wikipedia in any language, good advice to keep in mind is, "Consider the source", because just about anyone can edit an article
The most common meaning of "skip tracer" is a person who tracks down people who have fled, or "skipped town", particularly to collect a debt. But your figure really does evoke the legendary bounty hunters of the old American West, who tracked down and captured wanted criminals, to collect bounties paid for their capture. "Bounty Hunter" is probably better recognized, both in the English-speaking world as well as without.
I was a skip tracer, in my very first job out of college, and it was nowhere near as glamorous--or dangerous-as bounty-hunting. I sat in a call center and called people who had run up credit card debts, and asked them to pay my client next. It was interesting, for a while, and there were colorful characters among both the debtors and my colleagues. But I could stand it for only about a year, by which time I saved enough to go to grad school for a while.
So, "Bounty Hunter" would be a lot cooler.
Prost!
