Wideband handheld

I'm thinking about the LM-2 from Innovate. I'd like to be able to dial in the carbs on a few different trucks. I've never messed with any of these style products. I don't want to spend a pile of money. Will this product do what I want, or should I be looking at something else?

I've used Innovate MTX gauge that you install into car and love it. It's eye opening.

Been running my Innovate LM 2 for a couple years. No problems. Works great. It's installed in my truck, but I have a bung welded in the car and just pull it out and pop it in when I need to do any tuning.
