When I first got my ATPRO the guy I hunted with always hunted in Standard Mode. From reading zillions of posts I really feel like I'm probably missing out on alot by not somehow trusting in the Pro Mode. A few times I've tried to venture over to Pro Mode, only to find that the sounds are so different. I then digress right back to Standard Mode (where I am comfortable). My question is: How do I learn Pro Mode---which is probably where I should be? Does anyone else have (or had) this issue? I would sure appreciate any help. Thanks----Dan
