Any tips for drone useage on Skull Merchant?

I want her to be my main, but she's booty buns.

I have been playing DBD for around a year but started playing killer during the Masquerade last year (8ish months). I've unlocked every killer and played at least a handful of matches with each one. The ones who I've spent the most time on are stealth killers but I also play a lot of Freddy.

I want to get good at Skull Merchant but my drones seem nearly useless, and I end up just M1 chasing survivors most of the match.

Things I have learned playing her over the last week:

• Drones are good for info when placed near gens, if one turns white, it *usually* means there is someone working on the gen.
• If in the above case, I can recall the drone for some Undetectable and get a drop on them, but usually they bail before I get there. I assume they see the drone get recalled and gtfo, so this tactic is rarely useful, though it's had some success.
• A tip I was given this morning is to drop drones while chasing in a loop to get the survivor to leave the loop or risk taking the hinder from the scan line. I haven't tried this yet, but hoping it is useful.

Any other good tips on her drone useage (or just general gameplay tips for her) that might help?
