Need GPS unit advice
I've been using Garmin units for 6-10 yrs. The first was an Edge 200 and a couple years ago an Edge 130 Plus. I typically use the Edge 130 and keep the Edge 200 as a backup. I like the simplicity and don't need a lot of the enhanced functions of some units. But, recently both units are giving me bad elevation data. I spoke with a Garmin rep about the 130 and reset it. It had been giving me very high readings. After the fix it worked perfectly for a few rides. Yesterday I did a 1300 ft. ride and it gave me 400 ft. The backup 200 read 800 ft. So, I'm looking for a unit that is fairly basic. Any suggestions or ideas about what I should consider?
