Hi my friends and fellow treasure hunters 
A few weeks ago I got my hands on a defective Garrett ACE Apex detector.
Sadly that Apex got drowned and well had a bad water damage :/ the preowner didn't remove/disconnected the internal battery from the Apex and the Z-lynk headphones and just let it sit and "rott" for weeks/months
Well there was a lot of crusty gunk and a few rotten connections on the Mainboard of the Apex and the z-lynk headphones board. I did clean everything as good as possible and rewired and resoldered some bad and missing connections: now the detector turns on again, charging works - even the wireless headphone connection to the z-lynk headphones is stable.
The LCD ribbon cable had only one bad trace/connector (backlight) that got an extra wire soldered and then secured in place with hot glue.
But I still have some issues:
some of the surface mounted parts are getting very hot after a few moments/minutes after turning on the machine (photo with the marked area - and especially that small black chip; is that an diode?) and there is no detection activity at all when I connect the MF DD "Raider Coil" but sometimes some kind of "ghost detections signals" appear...
Is there any chance of getting schematics of the Apex Mainboard or is there someone here in the groups who has more knowledge?
My next attempt is replacing the 10uF 50V SMD cap in the marked area, removing the coil connector and check underneath and last step is putting everything in a ultrasonic bath
The alternative for me would be, to buy or trade me a spare Garrett ACE Apex replacement mainboard and just swap it out. If someone has a spare / replacement board and would sell/trade it - I just need the Mainboard, no Display, no battery, no case/housing etc...
My location is: 38678 Clausthal-Zellerfeld, Germany
Thanks already,
Marcus
