We have Garmin gear
as that is what we started with. The problems with the equipment
that I have found are (1) the proprietary chart formats and (2) that Garmin abandons "out of date" units fairly quickly. For example, we have a 2006c that is an excellant unit. However, Garmin's chart formats have been changed without a thought for "backward compatability", hence the lastest chart editions available for that unit are mid-2008 era. While these may be good for a few years more--changes have already rendered many of them unreliable. So, we will shortly have a choice between unreliable charts or new equipment. Likewise repair. We recently had a another Garmin suffer "black screen
death". While the unit still works otherwise, the center 2/3rds of the screen
is black. Garmin will no longer make repairs
to the unit as it's "too old" (8 years).
Think about it...
