I can get a 305 with HR and cadence for <$300, which, given the features, is probably a good deal for me. I could go with a Polar CS200cad, I suppose, but then I'd lose out on the GPS and more importantly, the altimeter. The threads in here on the 305 are pretty old, and I wondered if any of the negatives have been dealt with by Garmin in the past 12-18 months. Specifically:
1. I'm concerned about battery life. Contrary to my nic, I primarily ride metrics and centuries, so I'm often out for 5-7 hours at a clip. The longest rides are usually crowded and very well-supported (like the MS150s, Seagull Century, Lancaster CB Tour, etc.), so I could turn off the GPS and just use it for HR, cadence, and speed.
2. How is the battery life in the chest strap? Is the battery replaceable, or do you need to buy a new strap?
3. Has the training center software been upgraded? I'd probably use Sport Tracks anyway, but if Garmin has a better approach, I'd use that.
4. Has Garmin added a total odometer, or is this feature still missing?
Thanks in advance!
