I often see others using a high sensitivity setting of 16 - 20 on the 7000. Is there really much of an advantage doing this? I used to think maxing out my 4500 gave me some kind of advantage over the poor suckers who ran factory presets or slightly higher, now im not so convinced. 

Today i tested out my new 10" and 20" X-coils and tried many different combinations of settings to see what would suite me best. I did most of my testing with the 20" coil on a 2 gram bit of gold. I dug a skinny trench 200mm (nearly 8 inches) in some reasonably hot ground and placed my 2 gram bit in the bottom. High yield/Difficult were the better settings. (Ferrite and ground balanced, Semi auto ground balance,  Ground/audio smoothing off,  volume 8 (using a booster),  threshold 27,  threshold pitch 63,  volume limit 7)

First i tried a high sensitivity and the target signal popped out nice and loud. Then I started detecting the surrounding area and felt there was so much other ground noises going on that the quieter signals may be masked. Eventually I found my sweet spot where the detector was quiet as a mouse and i had no problems hearing a slight change in the threshold no matter how small it was. This was at a sensitivity of only 3.

I then went back over the 2 gram bit and it still gave a great response using sensitivity of 3 (although slightly less than when the sensitivity was a lot higher).

When i started detecting and raising the sensitivity up around 6 -8 a lot more ground noise came in. Now im used to ground noise as i used to use my gpx in Normal timings most of the time. But after reading how the zed is a different beast and not to drive it to hard i decided to try less aggressive settings to see if less is infact more. Obviously im new to the zed and have much to learn so will continue trying different things until i get my head around things. 

  

yes of coarse there is an advantage using higher sensitivity on a machine lol,,,it all depends how noisy the ground is the less quieter the ground is the higher you can turn up your sensitivity giving you more grunt on targets,,hope that helps

Ok this is my view ,,we all know the z is a great machine yes i agree it is,,yes of course the machine can do with a reduction of weight shaved off as waving this machine around for weeks months or years will finally wear your joints down,,know matter how big your shoulders,hips or arms are,,everything in life will get you at the end somehow or another,,,,its a fact

Minelab should of gotten half a dozen professional prospectors or so and invited them to there factory to get there opinion when making such a machine,,the price is one thing but the holding a brick all day is another, believe you me the next machine up from this will be the ultimate minelab  machine, were it will be lighter and more universal 

I bet you my bottom dollar Bruce Candy from minelab is working on a new design on improving and making a new model up from the z,,maybe they will call it the ZE or something,,,, whatever it is it will be the mother of all machines out there,,it will have less flaws and LIGHTERRRR of course,,,because thats whats on 99% of the prospectors wish list

The price of course will be ,,,,,you guessed it more DOUGH,,so boys find more golddddddddd,,cheers
