ProspectorPete said:Hi guys, I've been laying low for a while due to a busy time at work/home lately and haven't been prospecting or even visited the forum much of late but have just read this thread with interest regarding bigger coils on the Whites detectors.
I bought my SL new locally from an ex member to the forum and he did the hiccup mod before I bought it, I also bought a brand new Jimmy Sierra Grande 20" coil (black) from the same person who happened to had 2 of them as a custom order re-badged as Minor John.
Anyway, I tried it out before I bought the coil in very hot ground in the Maryborough area on a stormy day and apart from the coil over balancing the detector it ran very well with the pulse delay on 20 and HIGH conductivity the only issue I had was it would "scream" when I swung from left to right at the end of the swing, I soon realised I had my keys in my right pocket and this was setting off the coil.
We also air tested with a 2oz lead sinker I had in the back of my ute, sinker placed on the hot ground we managed to get a solid signal at about 3 foot.
I'm pretty confident this coil on my SL with the right settings will pick up a decent nugget at depth of 2ft no problems which is why I chose to buy it, I have since bought an extra extended leg to get the coil away from my feet and a harness, bungy, control arm to better balanced the set up when I choose to go nugget hunting in the right conditions.
Although the coil may only get used once every 1-2 years or 5% of my detecting time it gives me options which is something I like to have.
Anyway, that's my take on the large coils for the Whites detector, although I've only used it once it seems to work on this machine and can't wait for the opportunity to get back out and spend some serious time with it hunting for bigger nuggets. https://www.prospectingaustralia.com/forum/img/member-images/3820/1441785093_dsc07222.jpg

Strike A Light,, That ain't big enough is it Pete ?? I am going to have to get me one of those or the 14" MJ Mono, or both
Now that is a serious coil, I got a 15" concentric which is a VLFs version of a Mono and it can see those small 330ml coke cans at 3 to 4 feet, Heaven knows what that one of yours will do,
I remember when you first got your MXT, Now you have Turned in to a Cyborg, there's just no stopping you now,, lol
Thanks for posting it Pete,
John
PS How about a Name Change?? Terminator Pete He'll Be back, lol
