Eric foster Goldquest aquasearch?

[ginos]

Hello.
I have come into possession of this metal recently. Already I have another pulse marine Surfmaster pi pro detectorpro po' and more. This metal was stopped by as I was told more than 10 years. I loaded the batteries and charging and still hold charge. Impressive. I did different tests at home and the metal detector seems to respond well have different settings. I ask if you can have more information about this release of metal detectors. Or if you can make some special arrangements? Thank you.
I include photos

thank you lots Ginos. seems this board/schematic is same like i see in GOLDQUEST SS.
i do have only one pic of last but that is enough for me to get to conclusion.
marking on board is PPD4 too. looks Eric did one board for a line of detectors.

all the best

that's not an aquasearch--it's just a goldquest. the aquasearch is a water machine. first clean all that crud from the housing and around the board. then spray your board with some high quality contact spray/ preservative--like some DeOxit. no reason it shouldn't work.

Really from tests done is sealed as much as a excalibur

Okay, now that I see it much be some ancient model. --the Vi i'm guessing. Doesn't look that well sealed to me no gaksket just lots of silacone. Hope you can get it working not a bad circuit. rgrds, clive.
