Need to replace my depth sounder, and Nasa Target2 seems like a good no-frills replacement for my
20-year old broken sounder.

However, manual and web pages have only dimensions of display unit, no information about
installation options or how much space is needed for dashboard or bulkhead installation.

Not to my surprise, I have so far not received a reply from manufacturer to my questions.

Certainly 1-2 cm or an inch for cables? But do I need to tighten large wing nuts from inside etc? My
old display was bulkhead installation with four large screws that were tightened from outside. No
problems with waterproofing (surprise to me) and very easy to install.

Thanks in advance to any Target2 owner who cares to comment.
