The electronic manufacturers are creating new products with better displays and more features most of which one doesn't need. This is much like the "development" of things like MS Office. Who needs all the advanced features and tools in the latest and greatest? I have found that some ancient versions of these programs have more than enough tools and bells and whistles for my needs. So there is no need to upgrade. Of course MS stops supporting the old versions and so you often are forced to buy the upgrade. When it is a new OS upgrade you often have to upgade all your software
Admittedly the new products outshine the oldies... but you pay dearly for this. I've been using a 30 yr old B&G suite and it works fine... I have had a slew of position "fixers" beginning with LoranC and stand alone GPS
and now have a on old Ray MFD which is starting to show wear. Connected to it is a radar
so the upgrade will be spendy and likely an N2K system and new wire and cockpit
repeaters and on and on.
I recently bought a B&G Zeus Touch which is "portable" with a self contained antenna
... and sits in a winch
under the dodger
. It's stand alone without any other inputs. Very handy and I don't use the Ray anymore... except to set a waypoint and get the course data from it on the cockpit
When the ray dies I will have to bite the bullet with a new N2K suite with radar
, cockpit displays and so forth. I am thinking about another Nav station mounted Zeus.
