Garmin 405CX Review

Usually I'm at the forefront when it comes to gadgetry, but for some reason my GPSR's upgrade cycle is a little behind schedule. I've just upgraded from the Garmin Forerunner 205 to the Garmin Forerunner 405CX with Heart Rate Monitor. The 405cx has been out for some time, but it's been out of my price range until recently.  I was able to sell my 205 for a great price on eBay making the upgrade very much worth while.

I logged over 1000 miles with my 205 and cannot seem to run without a GPS these days.  I love the data it provides. The 405cx provides me with all sorts of data both while its being used and after the run.

First impression: The learning curve to use the device was a lot compared to my 205.  The 405cx is a little more involved because needs to be paired with the heart rate monitor and you have more options to configure in the training mode.   Several other reviews stressed the importance of reading the instruction manual and what can I say.  They were right.  I did the typical thing and just started playing.  Spend five extra minutes with the manuals and you'll be able to navigate the device like it's second nature.  It becomes really intuitive once you understand the main functions of the bezel. I now take advantage of the training options I didn't' with my 205.

The construction: I've only had it a few outings, but the construction seems to be what you would expect for this device.  It's IPX7 compliant so you can run in the rain without worry.  The heart rate monitor is constructed well and is not to noticeable when I'm running.  Once you get a good sweat going the electrodes are pretty accurate in measuring your heart beat.  The ANT+ wireless module is absolutely amazing in itself (on OS X).  My device transfers data when I get within about 10 feet of my computer and pushes all that data to my online log.  It also works well with Daily Mile if you desire the social aspect of sharing GPS data.  I'm a little concerned with the battery life.  It's rated at eight hours of receiving and two weeks on standby.  Running I should be ok, but hiking may be another area where I may need to find an alternate GPSr to capture my data.  Bottom line is it's going to last if it's take care of.

Data:  What can I say.  I'm a data nut when it comes to running, hiking or whatever I'm doing.  I love reviewing the pace, elevation, speed and geographical information that a GPS provides.  This one gives me the added benefit of a heart rate monitor and programs my splits.  Tells me I need to run harder to get into the higher levels of my aerobic zone.  In the graphic you'll see a snapshot of what Garmin Connect will look like when you transfer data from the device.  It's enough for me right now.  You'll see you can download KML and GPX formats to integrate into Google Earth or any GIS projects you may be supporting.  Elevation data is available too.  This was a pretty flat run, but you can see the bridge I ran over at the beginning and end.

Overall:  I may be impartial because I just bought the 405cx, but with a 1000 miles logged with my 205 I can say it's a welcomed upgrade.  The forerunner series GPS's are my favorite for running and this is primarily what I bought this for.   As of now I'm happy with my investment.  It's money well spent for your beginner to intermediate cardio junkie like myself.
