I have the si, and it is worth every penny. I fished bays I've never seen at Kentucky Lake this year, and found structure in deep water that you wouldn't know about unless you snagged it by chance. It's as easy as marking it as a way point, then driving over it with the fish finder, and if it's holding fish, the you stop and catch them. If you only fish water that you are use to then it might not be worth the money. I thought a vexliar was awesome, but that si capability makes a vex seem like black and white tv. I can't wait to see what they come up with next.
