Dose it have the upgrade. I find it's a $50.00 well spent. Excellent zoom function to show the bottom 5' of the water column. Very quick turn around from Marcum also.
Well I know my older one does, haven't tried this one out to know.
I know it is the 2.0.
Nope -Marcum has a $50.00 upgrade here for older units:http://marcumtech.com/upgrades/troller-upgrade-to-2-0.htmlThe also offer it in the newer Digital showdown Troller Here:http://www.rapala.com/marcum/fish-finders-sonar/showdown-troller-2.0-combo/SHWDT-2.0CMB.html?start=6&cgid=marCum-sonarThere are 2 levels with the Troller 2.0. Look at the face plate of combo and you can see the difference in the buttons. The upgrade is well worth the investment.Ross
