SDC Vs 6000 & Geosense

Did we ever find out what Geosense is?

I believe a buzzword for auto sensitivity combined with auto ground tracking, so nothing really, Gold Monster DNA, we saw it there first 🙂, well... the CTX has it too, but first in a gold machine.

Not the only feature I think likely borrowed from the CTX.

Geosense is simply an automated way of altering the CPU code on the fly. The ground minerals sensed by the CPU automatically alters the receive code to filter more efficiently. Plucking the tiny metal signals from  the overall receive signal. The 6000 is a triple channel detector and 2 of these channels are 'MPF like' with only one being dedicated to code seeking deeper targets. Interesting that MPF is no longer being touted as a technology on the box anymore. Wonder if the patent is still active????

So is the 6000 "significantly" different (improved) to the SDC in terms of being able to detect small gold?

Absolutely it is, as can be attest by all the gold being found by 6000 users in thrashed locations.

In certain situations the SDC is still the better choice and beats the 6k IMO, in particular in grounds with high hotrock burden and magnetized small particles. The MPF timings paired with the small mono coil can really make a difference, in particular because the 6k tends to be rather sensitive to hotrocks. But in every other situation the 6k is superior.

As JP says....YEP! Its most definitely a significant improvement.... perhaps one of the three channels is MPF-like, with the super fast sampling on another one for the tiny stuff. The triple channel has certainly added an extra layer of PI sensitivity.

I would say that is perfectly true. I can barely remember ANY hot rocks I ever got with the 2300 ...

Maybe a 10x5” DD should be a coil the aftermarket companies could make to help with the ground effects.

When you dive deeper into the patents for the various detectors many are shared between models.

The above are the 6000 patents, mostly all older patents except the top one on the list which was a 2019 submission, it relates to shielding in a coil and electronics related to that.

The second one down is shared with the SDC 2300.

The 3rd one is also shared with the SDC 2300.

The 4th one is shared with the GPX 4500/5000

The 5th and last one hidden away at the bottom of the list, also dated quite old first submitted in 2016 is likely the secret sauce to the GPX 6000 over the SDC, a new signal processing technique.  It's not shared with any other detector.

So, while it does appear the GPX 6000 is just a pumped up SDC with nothing overly new it does have some new technology in it that was good enough to patent, although Minelab would patent their lunch ladies home-made tomato sauce for their canteen pies.

The new shielding technique I think is evident too, how good is the 6000 near power lines compared to the prior GPX series.

So while Geosense seems nothing more than Auto sensitivity combined with Auto Ground tracking, the secret to the 6000 is not so much Geosense, but the new signal processing technique from the 2016 patent.

It goes to show how long they work on detectors though, a 2016 patent being the secret sauce, and they likely worked on it for years before it was a final product for patenting becomes a detector released in 2021.    It does make some of the smaller mistakes they make like twisting shafts seem rather crazy when years go into developing the electronics and a couple of days slapping together a shaft that should do the trick.

While it shares a lot of DNA with the SDC, more so than the earlier GPX, it's not just an SDC upgrade using all existing technology.
