I love my showdown 5.6 dual beam. I use it up at Lake of the Woods fishing eyes and sauger in 16-30ft of water. And then come home to my panfish holes that are in 4-10ft of water. I love everything about the unit. Battery life is great and crazy easy to use. I really like it for taking out a youger or first time ice fisher. And as far as the cheap ducer arms marcum provides you can upgrade to a aluminum arm to insure that it will not break. This is not an option made by marcum, it’s by a second party. How do you like your Lx-7? I am looking to pull the trigger here any day know.
