(used) Garmin Edge 305: should I expect more?
I just picked up my first GPS device: a used Garmin Edge 305 from ebay. I used it once on an almost-treeless road ride and the map looked accurate enough.
My second time using it, and neighborhood spin over to a wooded and steeply sloped trail netwrok has me wondering if this thing is faulty and whether or not I should send it back and ask for a refund.
- I pressed 'start' in my driveway, yet the ride file shows me starting about .65 miles from my house.
- I elevations for the first half off the ride showed me at ~220', but are actually 500'. the second half of the ride it got it right.
- I climbed and descended a trail, yet the route file showed my climb and descent as being about 1/8 of a mile apart for most of the trail segment.
I've heard these things lose signal in trees etc., but should my start point and elevation be that far off? Did I get a lemon or are these things all typical?
thanks for any insight.
