PhaseTech Posted April 22, 2016 Share Posted April 22, 2016 Yeah pretty sure I'll be chopping up an old 18" round skidplate to adapt to the 19Z coil. A 12" round GPZ coil would be dynamite. Thinking how deep one might dig a 1 gram piece running Normal (in suitable ground) and HY just boggles the mind. Anyone else wish there was an intermediate ground setting between Normal and Difficult? 2 Link to comment Share on other sites More sharing options...
Tryhard Posted April 22, 2016 Share Posted April 22, 2016 I would love to see a Ground Type between Normal and Difficult as I find the sensitivity difference between the 2 way to bigger a gap. 1 Link to comment Share on other sites More sharing options...
goldenoldie Posted April 22, 2016 Share Posted April 22, 2016 I suppose there is a skid plate attached to this new coil however looking at how the loops overlap one another the skid plate must have a step up and down at their overlap points.

RedDirtDigger Posted April 25, 2016 Share Posted April 25, 2016 I can't wait for the 19 inch coil to come out. Since upgrading from a 4500 to a 7000 I have had to drag the crowbar out of the truck to dig holes many more times compared to when I used the 4500. With a 19 inch coil I am sure the crowbar will get a good work out. I am busting to look for deep large gold on some old patches with the new coil. In virgin deep ground where the gold is over 5 inches deep (99% of the time) and the surface of the paddocks/slopes are full of BB's and wire I have been using the double target response of the Zed coil to discriminate out shallow rubbish and I have been only digging the deeper single signal targets with success. I can cover a lot of ground and am possibly only missing the odd bit of shallow gold. I am guessing with the 19 inch coil the double target response will occur down deeper to say 7-8 inches?. This will be a benefit in some particular spots I have where deep gold lays but the surface is absolutely trash filled. cheers RedDirtDigger 2 Link to comment Share on other sites More sharing options...

Would love to see some pics RDD of those holes you speak of that you have had to dig with a crowbar. 1 Link to comment Share on other sites More sharing options...

Hi Goldenoldie, The crowbar was for digging in hard clay with quartz debris in it and other hard soil locations. . I have been digging targets 2 feet deep and deeper with the Zed regularly and a crowbar is a must in some ground types. All the very deep crowbar dig targets I have dug with the Zed were scrap iron from the 1850's diggers unfortunately. The deepest piece of gold I have found Zed was around 20-24 inches deep....a 3 ouncer. 8 Link to comment Share on other sites More sharing options...
AussieMatt Posted April 26, 2016 Share Posted April 26, 2016 I think the GPZ19 coil will be a weapon but still not sure I need one yet With the standard GPZ14 coil I dug a piece of very old rusty steel that looked to be a bit off some sort of steel strap. It measured around 100m-150mm long (4"-6") x 25mm wide (1") x 3-4mm thick (1/8"). From the surface it was a very faint signal & I wasn't really sure it was anything to start with but once I got digging it soon brightened right up. I ended digging down to about 600mm (24") until I struck tree roots which I couldn't break with my pick due to depth/angle. At that stage I was getting hopeful but after returning with the camp shovel & cutting through the roots out popped the rusty junk. My pick handle is a measured 900mm long (36") & guesstimating the final depth I'd say it was at least 700mm down (28"). The ground at this spot is fairly mild & mostly pretty easy digging but there are some very hard, compacted clay areas or even layers too so I can definately see the need for a good shovel or digging bar. It's an hour or so of my life I'll never get back but the anticipation of what might be is what keeps us going back for more - I think I can only guess at this stage but you would have to say the GPZ19 coil will get better depth than that?

goldenoldie Posted April 26, 2016 Share Posted April 26, 2016 Thanks RDD for your reply and the pic of your nugget. Unfortunately Iron and Steel produce a better response than Gold. Link to comment Share on other sites More sharing options...
schiara Posted April 27, 2016 Share Posted April 27, 2016 I just have one question, when will the new coil be available in the USA. I'm inching to get one as soon as possible. Anyone have any ideas of when. Link to comment Share on other sites More sharing options...
