I have one, wife and I used at lake Hartwell in the ABA couples nationals, finished 10th in nation. Don't know if it was the reason, but would not fish without one now! Minnows realy get to jumping when we turn it on.
Used one with Jamie Wells on suspended bait. It brought the fish & the bait to life after 45 min. of nothing. My partner & I will have one soon as he sells this brand new Hummingbird 898 he won in the State Fed Tourney. You need to fish with some one who has on Jon. But right time & place makes a differ too.
Go you are trying to stir the pudding I think!!
A guy in my club got one from Tackle Warehouse when they were have a discount on all items sale in Nov and the jury is out. Right once right time just like the A-rig
