I purchase this as a upgrade \/ replacement for a 5 year old Garmin 60c . my old 60c be a steadfast companion on myriad canoe camping trip and have help I out of dicey situation many time . this newer model be strikingly similar except for some small but significant change . ~ the receiver be far faster to lock onto sattelite and fix position ~ the receiver have much greater sensitivity - this one actually can lock on and follow I in my house ! ~ battery life be slightly improve ~ syncing to a pc seem easier and more solid at Amazon 's price I pay $ 110 - less than I do 5 year ago , and that be at a good discount .
