Perhaps XP sees the Extreme Hunter as way to introduce the Deus to these business.
I know the Deus is common on archaeological digs, which I would consider commercial, although maybe not necessarily appropriate for a machine like this.
I'll only say that after spending decades in marketing it's unlikely XP doesn't have a complete understanding of the potential market for this detector. Businesses don't usually just 'guess' their product will be successful, they do their research and cost analysis. How they measure success is up to them.
It may also be useful on shipwrecks since the Deus 2 is submersible to 66 feet. I imagine it would be good at detecting canon under sediment.
