Hi Captain Sam. Great post, we have been following you for a couple years, you helped us find fish as we were going out of Muzuric one day. Thank you! On your post, how deep do you think the P-10's were diving at 20/20. The Precision trolling app wants you snapping at 50, so I think at 20/20 the app isn't calculating correctly unless I'm not reading it right. God Bless.
