Hi Boater Bob,
I would suggest you look at a Garmin 176. (Don't get the 176C. You cannot see it in the daylight). Smaller GPS's are too hard to read when bouncing over to Catalina. The 176 has a larger screen so you can see Long Beach, Newport and Catalina all at once and its user friendly. If you do decide on a smaller unit, I'll sell you my small screen Magellian real cheap.
