I recently got my second Explorer 11 from Ron in Ca. and I have been having a blast rehunting some of my old spots. I have had two 11's and two xs's over the years and I always sold them because of their heft. I went on a disability retirement last year and my arthritic wrists have stopped hurting since I quit working. Being pain free, I decided to try an Explorer one more time and I am glad I did. Though not a lightweight by any means, I can now swing the Explorer for 4 or 5 hours pain free.My line of work kept my hands and wrists in constant pain. I have probably over a thousand hours on my different Explorers and I hardly ever strayed from the settings that brought me much success, but recently I read a post about adjusting the gain higher on smaller coils. I have a Sunray x-8 that when the gain is set to the 5 or 6 that I usually use, I can't seem to hear the targets over 6 inches. Yesterday I put the x-8 on and took it to a very trashy picnic area, but this time I set the gain to 8 and gridded a 60 foot by 80 foot area off. I have found many wheats and 30's silver coins from this spot, but not too much recently. I took my time and hunted very throughly and in two hours, I found 14 wheat pennies from 6 to 9 inches deep and the trash was BAD. I was disappointed in the lack of silver and when I was about ready to quit, I got a signal just off the base of a small tree. 1935 mercury dime. After I dug this coin, I was thinking that I had put a coil here before or at least I thought that. I worked a small circle around the tree and I found two piles of coins on the opposite side. One pile had four wheats stacked together and the other pile which was 7 inches away had three more mercury dimes stacked together. All coins were frome the early 40's. Apparently a kid must have hidden his treasure away on a family picnic many years ago. These coin piles were both easy to find and I have no doubt a 200.00 detector could have detected them, but the other coins were a different story. Deep and surrounded by trash. Raising the gain made the deeper ones possible as I had the x-8 in the same spot a couple of weeks. Who ever wrote the post about the gain, I thank you. I always raise the sensitivity with a smaller than stock coil, but I never thought to raise the gain. I have seen some people poke fun at some silly questions, but these idiots are a minority. No matter what your level of experience, don't be too proud to ask questions. Just my opinions. R.L.
