Need Suggestions With Tom D Program In Water

[stateguy]

So guys what I am trying to say is I am hunting in shallow salt  water with Tom’s settings. 
I feel it’s like using the excal in all metal. At least that what I am telling myself. 
and I think it can have some real potential. 
I really like the 8 in coil especially in the water. 
Was wondering if anyone else is doing this and is there any tips or detecting modes there using. I am having a hard time understanding the target sounds. Trying go just use sounds not numbers. the beginning and end when sweeping over the target. I must be gettalot of small metal coming in 7-10 range and it’s junk. Think it’s small lead shot or split shot. Would like to have the gold sound better or sound different 
is there anything I can try adjusting or programming. 
appreciate any advice you give
