I would expect that to not work as well as the ol "crank-up". Height above the rig matters.
That it can be "aimed" is good though.
2008 F350SD V10 with an 2012 Arctic Fox 29-5E When someone tells you to buy the same rig they own, listen, they might be right. When they tell you to buy a different rig then they own, really pay attention, they probably know something you don't.
Trying to build a better mouse-trap again, hum?! Well, if they market it and claim it's the best thing since Grandma's Apple Butter, I imagine someone will purchase one, then be posting on these forums how disappointed they are!
You know, the old style spring loaded mouse trap on the small wooden board is still the best, and I've tried several new-fangled inventions to catch mice too. Same is true (in my opinion) with the old style bat wing!
It's kind of like that 55 year old antenna on the roof of my house. It pulls in television stations better than anything advertised today!
