Marine electronics

OK, so I’ve posted here sporadically about purchasing a Hunter 272. I know that I at least need a depth gauge and a wind instrument. I figure if I get the boat purchased and pulled for bottom paint and ready for transport to its new home that now would be a perfect time to upgrade to some digital gauges.

This is where it gets confusing for me. I’m familiar with the Raymarine Tripack, but I’ve seen similar one piece displays that are able todo the same thing.

The problem is, I’m not sure which ones to look at and what would be needed in the form of cabling, transducers, wind instruments, etc.

Some advice would be appreciated. I don’t have a lot of sailboat friends that I can turn to.
