I picked up my new 15 inch EQUINOX coil put it on and headed to the beach to try it. Running in beach 1 mode sensitivity at 20-ground balance, tracking on and recovery speed at 4 and all I can say is I have missed a bit with the 11 inch coil. Some coins pulled out from over a foot deep all the sinkers were with the 11-inch coil due to being in the water here are some pictures.
