GPZ 7000 Difficult High Sensitivity Vs Normal Low Sensitivity?

[Ethan in Adelaide]

Anyone can tell which goes deeper?

 

In some ground I have been running Difficult 15ish but I found I can also do Normal less than 10. What would be the go? Any much difference?  

 

Thanks,
Ethan

I've done a fair bit of testing between normal and difficult in my soil, in saying that my soil is often very mild and I can run sensitivity maxed out in normal.  Low sensitivity normal for me beats high sensitivity difficult every time, I haven't found a situation where difficult outperforms normal thus far in my soil, I don't have specimen type gold to experiment on though and not sure if that would make any difference.

It would be best to bury some targets and find out for yourself or wander around in difficult, find weak signals and switch to normal and see the difference. 

Keep in mind doing this switch back and forward between normal and difficult may lead to you encountering a software bug with the GPZ where your audio will disappear, don't panic.  You have to power it off and on again if this happens, a known software bug.  This is how I encountered the bug, doing just this process on many targets checking the performance difference between the two modes.

Normal on the GPZ is very powerful when run in the right soil, I can imagine trying to run it in the wrong soil would be more of a hinderance than a benefit though.

You should try run on normal sensitivity of 1 and have a little experiment, it's pretty interesting how well it does in such low sensitivity.

I’ve tested this many times and there’s no golden rule sadly - as with most of our conversations here on DP, results are variable depending on the ground. On some of the heavily mineralised ground I hunt small pieces (sub 0.05) don’t even register in normal because the background noise swallows up the signal even at low sensitivity, but they sing out as distinct targets in difficult. Conversely, on a quartz tailings piles you bet I’m switching to normal - it goes WAY deeper on specimens, especially if you can crank up the sensitivity.
 

I like to go over heavily mineralised spots in difficult HY with highish sensitivity (16-18) first and if I hit gold I’ll clean it out in those settings then try again in normal with lowered sensitivity. In some cases I’ve uncovered more gold, but more often than not end up digging ground noise for an afternoon. If there’s bigger gold in the area I’ll persist for as long as I can stand it.
 

Over the past few weeks I’ve been experimenting with lower sensitivity (12-14) in difficult HY as recommended in previous posts by JP and my gold takes have actually increased, but I’m not sure if that’s because of the setting change or just dumb luck sticking the coil into the right spots. It’s certainly a quieter and more pleasant experience though.

thank you good enough. I always thought as long as its normal then its better, appeared not so...

I thought the same thing a couple of years ago when I first got my 7000 and was shocked when my prospecting buddies were doing better than me with their 2300 and 6000. I went away to Inglewood with them (which has some patches of very variable, highly mineralised ground) full of confidence that I had the most powerful machine available and would come out tops using it at its max power in normal HY. I got absolutely caned by them, coming home skunked and with my tail between my legs, while they both did really well. I now use difficult HY sense 14 in that spot and come home with a competitive, if not tops, gold take. I use normal wherever I can, but difficult where I must.

Think of it like driving a car in snow (highly mineralised ground), you'll slip and slide everywhere, put your snow chains on (difficult) and suddenly you can drive fine.   When there is no snow (mild ground) you can drive around in normal fine, you wouldn't want your snow chains on then as you would lose a lot of performance you otherwise have with them off.

There is a reason these settings exist, if everyone could go around using normal then difficult and severe wouldn't exist.  

You have to be in the settings to suit the environment you're detecting, using the wrong settings even though more powerful can reduce your performance, not enhance it if used incorrectly.
