Hello all, Decided to buy the SDC 2300 last week. I put it to the test this weekend. Manage to find 5 nuggets in an area which I had hunted before with the GPX. Smallest one was .13 grams up to about .5 grams. I usually only use the 11" round coil (mono) with my GPX, so the smaller coil of the SDC seemed to outclass the Minelab with the 11" coil on small gold (as expected). I also want to mention, the targets were loud and the gold was only 1" to 5" deep. I enjoyed the machine a lot, very easy to use- especially if you are used to using a PI. One note, the machine comes with rechargeable batteries which only lasted me about 3 hours (which I thought was low) but maybe they weren't fully charged. I had bought 2 sets of Duracells for backup, which I was thankful for as I was along ways from a location to buy more batteries. No major complaints for the machine- it is pricey, but I plan on using it more in the future. Enclosed are some pics and a video. Good luck out there.
