Re: Used equipment
IMHO, the other thing that is worth it in older gear is the autopilot, and then only if it can at LEAST communicate via NMEA 183, version 1.5 or better.
If you are intending on going cruising then everything else is obsolete, some of it cost more than it is worth to remove.
There are just too many things like VHF with built in AIS, HD touch screen chartplotters and HD radar out there, all of them great for function and add a safety bonus; sticking with old stuff is penny wise and pound foolish.
Lessons learned are opportunities earned.
