I was rummaging in a not often visited cupboard yesterday and I found myself with a strobe gun in my hand that I didn't know I had! I don't even know where it came from, so I hope I haven't borrowed it and forgotten who it belongs to.
It's a yellow Gunson, the same shape as the one I pictured above but a 12 volt with an inductive sensor. The thing is that it has the adjustable sensitivity that you mentioned might make it work on your Monster Patrick.
I know that you have another type coming to you, but if that fails, then you are welcome to try this one. Obviously I will make sure it's working first.
