the vulcan does forward scan yes
check out the
alarm volume on the unit. my vulcan 5 is almost non existent (check out my videos on youtube, and on this site)
I use the vulcan 5 at the
helm, and would prefer a more robust one for down below, which i will get a Zeus3 at some point, but is too big for the helm for my
boat.
unsure if the vulcan 9 can show
radar
I would say, at this point, the Vulcan 5 is not ready for prime time. have spent a lot of time on the
phone and
email support with various issues, with varying degree of support (60+ minute on hold time, wrong answers, etc). still the Vulcan 5, for me is still the best choice, 5 inch, NMEA2000 connectivity and (future) forward scan.
Im going to assume they worked out some of the bugs by now with this newer, 9, model
I prefer buttons on the plotter, having an touchscreen only takes some getting used to.. the BIGGEST problem i had was the pinch zoom... if you pinch top and bottom (vs side to side or diagonal) it pulls down a menu.. so annoying! with a 5 inch
screen, its hard to not bring the menu down.. likely not a problem with the 9
