Got lucky at the lake today with my Makro Multi Kruzer, 19kHz, 2 tone, sens 55. Found a total of 5 rings, but only one of them was gold. A star shaped 10K ring weighing 7.6g. Gold #4 fty. Also found a few other pieces of jewelry as can be seen in the photo. Love being in the water especially when it's in the high 90's.
