- I've been running
- I've been working
- Toss in some sleeping, yard work, etc.
Also, looking at some of the GPX tracks, it appears that the 610 seems to cut the corners short, thus maybe causing the slightly shorter distances.
Compound this over a 75 minute run, you get a different of 0.06-0.07 miles over a nearly 9 mile run. Examining the GPX data, I haven't seen the apparent "jaggies" that I saw when using my 1st Garmin 610 watch. I am running using my new watch with Every Second recording.
Also, I am still running with my old 305 HR strap, I am supposed to be getting the new strap that comes with the 610 today.
After 5 days with the new watch, here a my pluses and minuses for the watch:
- Vibration Alert and actually being able to hear the watch
- Size of watch. Nice and small.
- Variable on watch are just as easy to read as on 305.
- I like the magnetic charger. I've woken up too many morning where my 305 slipped off the dock and was dead.
- Auto Scroll: Time-of-day window cannot be shut-off
- Automatic Upload to Garmin Connect, etc. is kind of quirky. Takes a long time, the ANT+ agent seems to get stuck at 44% for minutes on end.
- Clearing the Timer Started/Lap windows manually in the hopes that the GPS accuracy doesn't pop-up.
- Apparent delay when starting the watch. Seems to lose 0-8 seconds on that first lap.
- Rapid decrease in pace when taking corners (especially sharp turns).
Editing: A commenter alerted me to a GPS review of multiple GPS watches by DCRainmaker. See: http://www.dcrainmaker.com/2011/06/2011-sport-device-gps-accuracy-in-depth.html
Look at the results for the "Rambling Loop" test. Notice how the 610 comes up way shorter than the other devices. I wonder where I've heard that before...
