Garmin Forerunner 305 GPS Receiver With Heart Rate Monitor

Excellent heart rate monitor/gps combo. All the information is there. The provided software provides good feedback on my performance. I have been able to develop courses and distances on neighborhood routes, including maps. Great on backpacking trips. I haven't used all of the functions yet, there are just too many. This was a good buy.
Cons: The first one I bought died after 3 usages, but was promptly replaced by Amazon. And it is BIG.

Easy to set up and use. Great software included. Somewhat bulky, but the GPS surpasses anything out there. Works even in heavily wooded areas.

This watch is AWESOME!! The heart rate monitor is great, and the GPS is very easy to use. I would highly recommend this to anyone who is looking for a workout tool to help them further their fitness level. Easy to use and comfortable to wear.

I received my Forerunner 305 for Christmas 2008. Unit is chunky on a small wrist which you could overlook if the performance was better.
Initially I kept losing satellite reception which I realize may not be a "garmin" issue, but it forced my computer to time out.
But the software was difficult to install and the maps required a "purchase" for the motion based upgrade. Maps are hard to decipher and I did not find the support to be user friendly.

All I can say is I should have bought it sooner. I wanted this watch now for over a year and the price kept me from buying because I wasn't sure if it would be worth it. Now I can't imagine doing a run with out it. My only advice to anyone that's into running or any sport that tracks mileage is BUY one you are going to love it.
