I have an old Garrett Master Hunter 7 that I purchased back in the '80's. It came with two battery holders, one that held six 9-volt alkaline batteries and another that held four 7.2-volt nicad batteries. Why would the holder for the lower voltage nicad's hold only four batteries? It doesn't look this would provide enough power for the detector but it always seemed to work fine on the nicad's.

One set of batteries runs the detector circuits the other runs the display if it has one and the audio. Those old detectors really ate up the juice Ice

The detector holds only one battery pack at a time. The nicads are the primary power source and the alkaline pack is for backup.

I dont exactly know but i do know it would depend on how each battery pack was wired, in series or parallel , this determines output.
So essentially each could and apparantly are wired in such a way that each provides the same output.
