Hi all,.....first post here.\n\nI have an older 60CSx that has served me well for 15+ years, and it's time to upgrade. While having some GPS knowledge I am by no means a techie, and am getting totally confused with the available offerings on the market today.\nHere are a few questions I have for those of you with lots of experience.....any help would be appreciated.\n1. Are there any current models that take both AA batteries and a rechargeable battery pack?\n2. If I just wanted basic Inreach SOS capabilities with the lowest plan what models cover this?\n3. If you were replacing a 60CSx in todays market, what would you replace it with?\n4. Need barometer and altimeter\n5. Can the newer models still be used with Basecamp? I have lots of saved files. If not, how stable/what is the current alternative that people are using?\n\nI have done some research, but all it does is confuse me! :-).....I'm a senior, perhaps that's why!! LoL\n\nThanks in advance for any advice....I'm sure I'll have other questions but this will do for now.\n\nThanks.
