Quality, performance, and customer service: the White's commitment, since 1950.
I received the new TDI detector on a Monday and was chomping at the bit to try the new Pulse Induction technology out. I have been extremely successful with the GMT and MXT in my nugget hunting searches. I had just acquired 5 new claims and wanted to try out the new machine. It was going to be a challenge, because I had grown so used to just turning on a machine and off I go.
I read the manual carefully and decided to head out on Wednesday to one of my new claims. I had acquired all of Sherlock creek where it flowed into the Merced River though section 14 in Mariposa County. It promised to be good pickings. The ground here is heavily mineralized and full of hot rocks, so I was anxious to see how the machine performed. I had also brought my old reliable GMT and MXT along in case I had problems running the new machine. Hard to break old habits.
The TDI had come with two coils. I put on the 7.5 coil and it was rocky and the area was full of crevices. I set the gain at 5 the pulse delay at 17.5, the ground balance at about 7. I also set the target conductivity on low and the frequency about half way on the dial. I always set my threshold at a barely audible sound when I run my machines. I was off and hiking up the creek bed with the new machine. In the manual I had been told to listen for a high wee wee sound for gold and other targets would sound off with a woo woo sound.
This seemed funny to me when I had read it. About 100 yards up the creek I got the sound that I had read to listen for. I had hardly got any of the woo woo sounds, which delighted me as I was used to so much trash on my old claim. At about 12 inches I was rewarded with my first find with a PI detector. It turned out to be a 1/2 ounce nugget. It was located at the base of an outcropping of bedrock in the main creek bed.
I edged my way around the outcropping and soon was rewarded with a strong sound again. I began to dig. I dug and I dug and I dug. I was not used to digging so deep for a target. I kept running the coil in the soon to be large hole to check for the target location and to reassure myself it wasn't just digging to China for a false signal.
At about 15 inches I was rewarded with and incredible lump of gold. It was the biggest piece I had ever found. The lump of gold turned out to be 7.475 ounces of a gold ball sized nugget. I have to say I was praising Jimmy Sierra for developing this detector. My knees were beginning to bother me so I decided to head back in to my Bronco and head home. I was facing two knee replacements and the right one was bone on bone with no cartilage. Hiking is painful, but well worth it with this new machine. I cannot sing enough praises over this smooth running and easy to operate.
