Anyone using the Deeper PRO+ Smart Sonar

I don't have a finder on my new Coosa after selling my old Coosa with the finder with it.
Has anyone tried the Deeper Pro Smart Sonar finder?
I'd be interested in your perspective. Thanks.

If youre mobile on a kayak I don't really see the appeal of these myself...

You have to mail it overseas (a) to replace the battery which folks say lasts for one year, or (b) for any other service.
