I updated to V4 when it first came out and finally took the detector out for a two hour test run this morning. I stayed in Basic 1 and did pretty good for only a couple hours of detecting. Found a bunch of coins, a few pieces of silver jewelry and a solid copper bracelet. It seems a little more chatty and the quarter signals don't sound as crisp as I remember them being in the previous version. They seem smeared. I'm sure I just need to make a few minor adjustments but overall I really like it. Time to start reading up on V4.
