it wasn't me.the first 10 k I found within 5 min.s in about ankle deep.( my pi pro is still at whites so I can't go to deep.) the teeth was found about 3 hours later in knee deep, then about 20min.s after that got the 14k, again in about knee deep, my feet were num from the cold water but it was so calm an clear I had to get in.On the inside of the ring is 14k an on the other side it has 1/3,I take it that this is the cart size of the rock .I just bought a new digging tool for dirt hunting in the parks an then dig up this nice spade, guess I got a back up, the watch well its not waterproof.
