Read the manual last night, went through the different programs to familiarize myself to the APEX and charged up both the wireless APEX Module and the Garrett MS-3 wireless headphones. Got up early, did a pre-function test, and the components worked as they should. I had been planning my first water hunt for some time for today, so I thought I would use the APEX. To keep it simple, I hunted in jewelry mode, @ 5 KHz hoping to get a silver ring or coin. I manually ground balanced the APEX prior working the shallow water. I also attached the Garrett shoulder sling on the detector, in case I accidentally dropped it, the electronics wouldn't go in to the water. It took a little time to get used to the 5 different tones, and being able to adjust the iron audio is a real blessing.
Hunting in jewelry mode, I dug all the repeatable signals, and was pleased to see how easy it was to get a nice clear high tone on the audio, for all three coins.
Here are the coins I dug. This location gave me 3-4 silver quarters last year using the Garrett AT Max. The AT Pro just didn't seem to have enough depth to get a silver here. Getting a silver coin in the water with the APEX was a real surprise!
