I made several mods to my Cen-Tech pinpointer. I replaced the cheap switch with a better switch, added vibration, installed a coil wire on the probe to increase depth and adjusted the internal sensitivity. I get about 2-3 on it now which is not bad for a $17 pinpointer. Has anybody else tried out any mods? It is still not a Garrett Pro-pointer but it works great and alot cheaper.

Not Here but I'm all Ears.

Most can do with a Coil upgrade for sure.  A bit of tweaking and some can be quite good.

Please tell more.

I'm trying to get to the deeper coins. I just purchased a fisher F2 to go with the Garrett Ace 250 I have. I also purchased a 11x14 accellerator coil for the Garrett and it seems to go 2-4 inches better on the air test than the 9x12 Proformance coil. The Cen-tech mod seems to work well. They have them at Harbor Freight and seem to be getting pretty popular for the price.

I CAN'T BELIEVE IT!! Shocked
I was just thinking about modding mine today!!
I put a heavy duty zip lock bag over mine that fits perfect, and I have a junk cell phone that I was going to take the vibrator motor out of and stick it in the CenTech. (I already had it apart and saw the vibrator lugs on the PCB)
This unit ROCKS!!
I would NEVER have found that BB that was setting off my Cibola in all metal!
Saved me HRS of time cleaning out my coin test plot!
Ditch the Garret and get a Centech!
THIS IS A PINPOINTER!

If a person has the Know How and time, you can improve most.

Factory pre sets are for Geographic ares.

Most can be tweaked to fit the shoe.



 Cool

I think a lottery sounds good Grin. That seems like a great mod to the pinpointer, I will have to try that out.
