Gpz7000, A Look Inside

Recommended Posts

Have you ever wondered what's inside......... I know you have...... I have.......

While I'm Ukranian, I don't understand Russian but it sure was neat to see how much they've crammed onto the boards inside our GPZ's.

Interesting, but knowing nothing of electronics it is waaaaaay over my head, I sure can make one sing when put back together though :evil1:

It's nice to see so much SMD (Surface Mount Device) use and the double stacked boards. Notice the monster ferrite to reduce RFI/EMI on the coil connection lead. It would be interesting to see this compared to a CTX3030.

I assume it's out of warranty but I'm sure the folks at Minelab have noticed the clearly shown serial number and made note that if it wasn't before, it is now.. (grin)

Spell it out, use your phonetics and you'll figure it out.

All of the older minelab units, minelab would spray paint the boards white, so no one could reverse engineer them. But I guess now since it's all microprocessor, they are not worried about it anymore. Thanks for showing video Jen...

 In the beginnning of the vid( around 0:12 mark ) the narrator is poking around an inductor, I believe( the chunky cylindrical object... RFI= radio frequency interference, EMI=electromagnetic interference

I do not understand a word you are saying. Even the video is not understandable. He`s speaking Thai or Vietnamese

He's actually speaking Russian in the video.

First time I've seen the inside of a 7000 but I have to say Im a little surprised and shocked that they used what looks like a electrolytic capacitor on the power feed rather than a bank of carbon or polymer capacitors. :idunno:And yes I use large ferrite shields for EMI on the coil leads even on my old SD's. they work great.

Amazed to see NO CONFORMANT Paint on the PCB. Yes the Ferrite Cancels a lot of EMI.
