White's TDI vs Older Minelab machines?


Recommended Posts

Hello,

I have read that the White's TDI will not run as deep as the newer Minelabs like the GPX or GPZ series, but how do they compare to the older SD and GP series? I am currently using a GMT, and it seems to be working well for me, but at some point I would like to pick up a PI machine for increased depth. I use to own a GP Extreme back when they were the hot machine, and I loved it. I cannot afford one of the newer Minelabs, but would be perfectly happy with another GP Extreme if I could find one for sale used. I would also consider the White's TDI or TDI SL models, but can they keep up with a GP Extreme?

What is the going rate on a clean GP Extreme now? I've seen them from $650 - $1,200 on ebay recently, but they rarely come up for sale. Also, back when I had mine, you carried a heavy battery on your back, and now there are lighter batteries for them, is that correct?

Rob, do you sell older used Minelabs by any chance? Or DOC?

Thanks,

Jared

Hey Jared,

Welcome to the forums for starters.

The TDI is White's first run at a PI for gold. Minelab's first run was the SD2000 back in the early to mid 90's. Minelab has made the biggest movements in the gold hunting PI's from the SD series (3 detectors), to the GP series (3 detectors) and then the GPX series (4 detectors). Minelab is now moved into Zero Voltage Technology with the new GPZ 7000.

Both are great detectors, the TDI and Minelab PI's. The TDI can use Minelab coils and aftermarket coils.

I just sold a great conditioned GP3000 for $1500 about a month ago. I have seen the GP Extreme's from about $1000-$1500 depending on condition and accessories.

The lightweight battery system you mentioned is available for the SD/GP series, 4 pin, or the GPX series 5 pin. It's called the "Doc's Goldscreamer Power Pack System." It's a must have in my opinion as it allows you to be wireless and you don't have lug around the bigger battery or wear the harness. Here is a direct link to the battery system if anyone wants to look - http://www.robsdetectors.com/docs-gold-screamer-power-pack

Currently, I don't have any used PI's in stock. However, I would recommend checking the Classified section of this forum and others to see what is out there.

Hope this helps a bit. Glad you joined the forums.
