He's lucky enough to fish enough to get good at it... My truck has 3 bolts on the inside of the tailgate handle. they are shaped like a V. I line that up with the bow of the boat and i'm in line to the left and right. For font and back I've got the backup sensors that beep. As soon as it beeps solid my ball is under the receiver. If you're fortunate enough to have a garage I would hang a tennis ball where it would touch your back glass when you're at the right spot. The one downside to the aftermarket products is you have to put them on and take them off which is another thing i would forget to do when i'm trying to get to the lake lol.
