16 volt will give you a crisper, brighter image on your graphs. It does this all while giving you better returns from your transducer which results in clearer side, down and forward imaging allowing you to unlock the full potential of your graphs and make you a better offshore fisherman.Maybe you have already noticed your console units with engine running at 14.6 volts look slightly better then your bow units running at 12v this is because of the increase in voltage. 16 volt is also 20% more efficient than 12 volt, meaning you will get longer run times on the equivalent amp hour rated 12 volt. Example, 16V 80AH will get similar run time to a 12V 100AH.
