Some of the lower end handhelds are that way, especially the older = units. This marine unit however is identical to the aviation unit with the = minor exception of marine navigation database instead of aviation which can = easily be changed. Lowrance didn't want to give this little tidbit up due to difference in prices so I downloaded the manuals from their site and the only difference between the two other than the database of course was = the location of the function buttons (along the bottom on the aviation model = and on the right side of the screen for marine unit) Doug
