Makai has PC nav software, a Lowrance GPS/Plotter, and a raymarine
SL72C Plus Radar/Plotter.
The PC is our primary nav system and is linked to the GPS. The Lowrance has the world map and we just upload our routes to and shut the PC off until we are near our destination
. It works great.
We got the Radar/plotter primarily for the radar
. Since I did not want to spend the big bucks for the latest and greatest radar
we looked for models just being discontinued and found the SL72C plus Radar Chart plotter on sale
at Defender for $100 more than without (and saved $1-2K over the latest version). For very few dollars we have added redundency. The chips can be found by trading or used for very cheap
I believe that it is better use of the money
to buy at the best price
that fits your needs than buy because it is the latest technology. Most of the current
products are evolutions not revolutions of devices. For the extra money
it is not worth the buttons that will not be used.
