Running Gear Review: Which is the better GPS Watch and Heart Rate Monitor for Running: the Garmin 305 or 405?

Have you considered getting a GPS and Heart Rate Monitor Watch?

Having these features can help you improve your running program  A hear rate monitor is a useful way can help you determine if you are reaching your target heart rate or not, and can help you to track your effort.  The GPS feature allows you to track the distance you have run as well as your current pace.  Really, these things are pretty cool, and knowing how to use them can help you train better and smarter.  They can’t run for you, but they can do an awful lot.  I think these devices can even tell time, but I am not sure 😉

I have been considering purchasing a combined GPS and heart rate monitor myself.   I have not really bought into these ‘toys’ before, but now I am getting little more serious about my running.  Today I asked a friend what device he uses.  He noted that he used the Garmin 305, and was happy with it, but he was considering upgrading to the Garmin 405.  I decided to check into the two devices and share with you my findings.

There is a good discussion thread over at the amazon discussion board about whether the  Garmin Forerunner 305 GPS Receiver With Heart Rate Monitor or the  Garmin Forerunner 405 Wireless GPS-Enabled Sports Watch with USB ANT Stick and Heart Rate Monitor (Black) is better.

Some people are in favor of the Garmin 305 while others are in favor of the Garmin 405.  Those that are in favor of the 305 state that it has better accuracy with the GPS tracking, and they like the fact that this watch includes a small map of the area.  Those that prefer the Garmin 405 seem to believe that it is just as accurate,  and has a nicer design.  The Garmin 405 does seem to be a bit more ‘bulky’, while the 305 does seem more sleek.  Though, with a GPS running watch, I personally put accuracy at the top of the list.  Since I did see some real concerns about the accuracy of the Garmin 405, I personally am leaning toward the Garmin 305 for now.

Alternates:  Of course, if you want to look at alternates, you could look at the Timex Global Trainer Speed and Distance with Heart Rate GPS Watch Or the Polar RS800CX Multi Sport Heart Rate Monitor Watch with G3 GPS Sensor W.I.N.D..  I have not used these devices either, but they look like they could be good alternates.  If you have used these and have some feedback, then please do let me know what you think.
