you need to post this on the Minelab Explorer forum instead of the Teknetics forum.

Identification numbers should be marked on top, like the one pictured. But, Minelab and others will tend to wipe or sand off ID numbers so make it impossible to figure out the chip, most likely a common one costing $1 or less.
You'll need schematics, took a look around couldn't find any.
Since the board says power supply, its probably a power supply regulator chip.



Nokta/Makro Anfibio-Multi, DeepTech Vista X, and few others
Self built Mirage Pi's --- they work great in trashy areas!!

It's very likely to be a dual power mosfet, based on the way the pcb tracks are laid out. The same as the device just below it, in fact. Plus, it's a power board, so power-switching components are likely parts to find. However, it's not wise to assume it's the same as the other part - it could even be the complement, eg. an N-channel, vs. a P-channel.
Try cleaning it with acetone or similar, it may help show up some part numbers.
