A few Multi Kruzer questions. Zincs & copper pennies, modulation, and waterproof headphones. (1 reply)

I am very excited about the Multi Kruzer.
I just want to ask a few questions before I release the hammer.
Does the machine have a good enough target id spread between zincs and copper pennies?
Are the waterproof headphones inbound soon?
How is the target modulation?
Does it do a good job of loud sounds on surface targets, and soft sounds on the deep targets.

Thanks so much in advance. I know that only testers may know the answers to these questions but I figured I would give it a shot.
Oh and one more thing.
All the buttons are black. Any word on Makro coloring some of the buttons to make settings easier to adjust with highlighted buttons instead of all black.
Thanks again and HH
