I have had the ATX for a couple of weeks now and have taken it salt water hunting 7 times so far. I usually hunt with an Excalibur and an Infinium with great success. I found a silver bracelet on one hunt and two platinum rings on another hunt. I usually have good odds of finding gold atleast 7 out of 10 hunts I will find gold but so far with the ATX I am 2 for 7. I purchased the ATX to give me atleast a slight advantage in depth over my other units in the water but so far I am not convinced that I am getting any deeper with the ATX. I am going to do some comparison test with the ATX and Excalibur this weekend and report back.
