Working for a company perhaps like Garmin
would be excellent, although you would probably still be locked up in an office. It sounds like that is exactly what you don't want. Given you probably want to work outside and on boats, you may want to consider starting your own marine electronics installation
and service business.
Marine electronics are still nowhere near plug
and play and lots of boaters who have more money
than time need electronics professionals to come out to their boats to install the equipment
and get it working.
I just installed a Furuno NavNet
3D MFDBB (blackbox) system. It was nowhere near plug
and play and took numerous calls to Furuno
to get it working properly. Most boat
owners probably do not have the time, general knowledge of electronics or the patience to do this. Mounting the equipment and running the power wires and data cables
was about half the work. The rest of the installation
work was spent on the phone
and and changing system settings after it was powered up to get everything working correctly.
Marine electronics are not getting any simpler and it really is getting close to the point where it requires a professional to install the more sophisticated integrated systems.
I know of people who have such businesses in the SF Bay
Area, therefore it is a viable profession.
