Well, I am always interested in trying the latest invention for my favorite detector, the Minelab Sovereign. I was one of the first to try the Patriot meter and I still consider it to be the very best meter ever made for the Sovereign. Now, along comes the AMP and I just had to try one! I like to hunt with a very light setup because of some very serious physical limitations: bad knees, bad rotor cuffs and two very sore elbows. I used a nice straight rod with the S-8 coil which only weighs 2 pounds max and I used an oversized fanny pack that has been modified to slip onto a padded 3" Dewalts work belt to carry my GT control box and the AMP, along with a sidekick pouch that carrries everything else that I will need on a hunt. Everything I need is on that belt: my 9" bladed knife for cutting plugs & prying out cobbles at the beach, a bottle of water, cardboard tubes for separating the goodies & trash and I even hang my sand scoop on the handle of the knife. Saturday morning (yesterday) I went to one of my local beaches here in Carlsbad (Calif) and the first thing I did was to bury a Nickle, a Dime & a Quarter, just out of the range of my 8" coil and then I turned the AMP on and it very easily locked onto all three targets. I then proceded to hunt for two hours using the AMP and dug 37 good targets ($2.17) and I was quite pleased with how well the targets sounded off and I can honestly say that several of them seemed deeper than I normally expect to dig when using an 8" coil. That is exactly why I wanted to try the AMP! If I can get a few more inches of depth with my small (light) coil, it will save wear and tear on my poor body and allow me to hunt for longer periods without using a bigger (heavier) coil. I think Shaun's unit is very well designed and works as advertised and with his money back guarantee, I would recommend it to anyone who, like me is looking for a bit more depth without the trauma of using a larger, much heavier coil. Sovereign users know from experience that you need to hunt slow and keep your coil low to the ground for the best results and when using this new device, it is true as well. It is now a permanent part of my GT setup and I can't wait to get out with it again! Here's a picture of the fanny pack setup:
