I bought an AT-PRO a few months back and will be doing my first water hunt this weekend at a fresh water lake that has a lot of people fishing around and on the beaches in the spring and fall while they are closed, so I figure I will be hearing a lot of led fishing weights and want some advice so I do not spend my time going from one sinker to the next with little success on good targets. I have been a land hunter for almost 5 years now ( F-75) and love it but every time I have tried using it in knee deep water it seems the majority of my finds are trash/sinkers. I am still learning the language of the AT but have had good results in the dirt and hope it will carry over to the water. There may be no good answer to this question and that is what I expect but hope I am missing something because to my ears lead on both machines seems to be a clean, crisp and solid dig me tone.
