I was quite surprised yesterday, I hit a mullock heap in kalgoorlie with the 24dd on 4500. Picked up a little iron piece that the garrett with the standard dd could not pick up. It was only about 6 inches deep. I thought the 24dd was only for big targets and was really surprised it outperformed my garrett with a small target as the coil is only 11" or so. So with this I have three questions:
Question 1: Am i wasting my time with the garrett?
Question 2: Am i wasting my time with the 24dd, as these hit the streets along time ago and maybe it got more depth with older detectors so its not really new ground like I thought. I was thinking what are the chances someone has swung a 24dd over this area and how will it perform compared to the newer coils such as 18" camo elite.
Question 3: What are the iron pieces I am picking up from the mullock heaps, Just seems to be too many to be pieces of tools and they are also quite chunky.
Thanks for any info, I am a newbie at this been doing it for 6 months and trying to do a crash course in Finding gold, but haven't been so lucky
