Great watch for running indoors or outdoors
After using the Forerunner 305 for over two years, I decided to replace it with the 405cx and am very happy with my decision. But first let me address the main criticism of the 405cx and its predecessor the 405--the bevel and touch system.
Garmin is not Apple, so the bevel and touch are not on par with the scroll wheel on an Ipod or the touch on an iPod Touch--but they still work fine. Granted, if the bevel gets sweaty or I touch it with sweaty fingers (not something unexpected for an exercise watch) it becomes nonresponsive until I wipe off the sweat. But this is not a big deal for me. When I run I simply use auto scroll, which is unaffected by moisture. And if I want to override auto scroll by using a manual touch, it takes only a second to wipe the sweat off the bezel or my fingers. So don't be discouraged from buying this unit based on the bevel and touch.
While the 305 is a great unit, here is why I like the 405cx better. Note: I use this on an Intel powered Macbook running the latest edition of Leopard without any problems.
1. Although the 405cx is as thick as the 305, it is noticeably smaller and lighter.
2. I like the wireless ANT technology that automatically transfers data rather than having to place the unit in a USB cradle as with the 305 (though doing so is not a big deal), and also effortlessly pairs with my heart rate monitor and foot pod (which must be purchased separately).
3. The 305 has no power save mode, and I inadvertently drained the battery a couple of times when I forgot to turn it off after running or put it in the charger. The 405cx not only has an automatic power save mode, but you can turn off the GPS when running indoors to further save power. With the GPS turned off, barely any power is used. Also, this ability to turn the GPS off makes it easier to use the footpod when running indoors (the 305 first has to search for a satellite signal before realizing you are indoors, and that can take several minutes).
4. I find the bevel and touch system on the 405cx much easier to use than the buttons on the 305 in order to change various features. But I like electronic gadgets, and as I said above, the sweat issue is not a big deal for me.
Here are some tips:
1. Rinse the unit, the heart rate monitor and the strap after each use with plain water.
2. Keep the unit in the charging clip after each use to ensure you always have enough power. A simple touch of the bevel will tell you the percentage of power left. The charging clip can be powered via a USB port on your computer or via an electric outlet using an AC adaptor. The included AC adaptor with the 405cx is very clunky; I use the Apple travel charger for the iPod instead. Make sure the charging clip is properly attached to the unit or you will drain the unit instead of charging it (already happened to me).
3. Although the unit lists three training fields, there are actually four if you have the heart rate monitor--by default only the heart rate shows up in the first field, but you can modify that to include two additional data items.
4. Unlike the 305, where you can move forward and backward between data fields, the 405cx lets you move only forward. Therefore, when I run indoors I turn off my "outdoor only" data fields--grade, elevation, etc.--so that I don't waste time looking at them.
5. For a first time purchaser to whom cost is important, I would say get the 305. My reasons for switching to the 305 may not be important to you.
6. Buy the new version of the footpod rather than the old version (I have reviewed both on Amazon) for running indoors.
7. I use a Mac software program called Ascent that I think is far superior to Garmin Connect and Garmin Training Center, and unlike the former does not require an internet connection to upload data.
Bottom Line: I have had this unit for three weeks and run over 100 miles both indoors on a treadmill and outdoors in all kinds of weather--light rain, cool nights, and hot humid days. I really like this unit. Due to the bevel and touch issues I would have rated it 4 � stars if I could, but since there are no � star ratings I gave it 5 stars despite those issues because for me they are negligible compared to the rich features on the 405cx. If you are a serious runner, you will love this unit.
Update July 22, 2009: I have now been using this for about six weeks and logged over 200 miles. In that time I have had the bevel lock up due to sweat only twice: once in the gym and once outside. The point is that this is even less of a problem than I thought, and should not discourage you from buying this unit.
A more serious issue is with the ANT technology. Sometimes I will get a message on my laptop that the transfer of data to the laptop from the 405cx was not successful. I then quit the Garmin Ant Agent on my laptop (and sometimes remove and reinsert the ANT USB stick as well), restart it, and have to go through this process three or four times before the data finally transfers to my laptop. The problem began after I updated the ANT software, and I see from Garmin forums that other users have experienced the same problem. Hopefully this is just a bug that Garmin will fix in a later update. While I would not let this discourage you from buying the 405cx, just keep in mind that a wireless transfer of data, while convenient, is not always problem free.
Update August 21, 2009: Garmin released an update for Macs (and I assume for PCs as well) that solved the download problems using the ANT technology. Now the data transfers work perfectly.
The more I use this watch, the better I like it. Here are my latest comments:
1. The backlight is far superior to that on the Forerunner 305. It produces a much brighter light that I appreciate when running at night either outdoors or on the treadmill at my gym (the treadmill area is kind of dim at night).
2. The battery life is excellent. Even with BOTH the backlight AND the GPS on for a couple of hours, battery capacity is still 75% when I am finished running. What this means as a practical matter is that if you forget to hook this watch up to the charger after a long run, you will still be good to go for your next run. The battery life per charge on the Forerunner 305 is not as good, and sometimes when I forgot to charge the 305 between runs, the battery would die during the second run.
3. The "sweat issue"--i.e. the watch becoming non-responsive when the bevel gets sweaty--has become a non-issue for me since I haven't experienced any problem in months. Perhaps that is because I periodically "towel off" the sweat on my wrist and forearm during a long run.
Update January 9, 2010: I continue to recommend this watch as the best GPS watch for serious runners. Using it this winter has been a pleasure. Here is why:
1. I have run in sub-freezing temperatures where the "real feel" with the wind has been as cold as zero. I keep this watch around the outside sleeve of my running jacket so the GPS function is not impeded (as it would be if the watch was covered up). The bitter cold has had no adverse effect of any kind so far.
2. When I take a break during my run at a local convenience store, the watch does not fog up when I go inside, and after I have warmed up, it does not fog up when I go back outside.
3. I have run in light snow, which I just shake off the watch periodically without any adverse effect (and I did not expect any, since I have run in light rain during warmer weather without any problems).
In short, this watch is performing great during a very cold winter in the Northeast.
Update May 24, 2010: I have been using this for almost a year, and it still works great. On a recent vacation to Mexico, the satellite signal was picked up quickly and without any problem, and the same was true when I returned home to New Jersey. Also, I ran outdoors in very hot and humid weather, and was drenched with sweat. It just took a couple of seconds to wipe it off the unit so that it would function properly. Here is a cleaning tip: At the end of each run I stop the timer, then touch the Time/Date at the top of the unit to switch to the time, and then lock the bezel before I rinse the watch off. I found that if I tried to lock the bezel while the unit was still on the exercise screen, sometimes I would accidentally restart the timer. But that doesn't happen if you switch to the Time/Date before locking the bezel.
I still believe that this is the best GPS watch on the market for serious runners.
Update June 27, 2010: The other day after I had finished running and transferring my data, I noticed that the time was wrong on my 405cx. I discovered that the screen had completely frozen, and nothing was responsive. I did some quick internet research and solved the problem as follows: I connected the 405cx to the charging clip, which I plugged directly into my PC instead of into my USB hub. Without touching the bevel, I simultaneously pushed in both buttons for about 30 seconds, after which the screen unfroze and the charging screen appeared. The watch has worked fine ever since. I have no idea what caused the problem, but in case it happens to someone else, I wanted to list what worked for me.
Update November 4, 2010: I have now had this unit for over 16 months, during which I have run about 1600 miles indoors and outdoors in all kinds of weather year round, and it still works great. I have a few miscellaneous tips:
1. I have seen some reviews complain about battery life. After a 2 1/2 hour run outdoors I still have 70% of my battery life. However,...

Miles ahead of the rest
This review is from: Garmin Forerunner 405CX GPS Sport Watch with Heart Rate Monitor (Blue) (Electronics)
I really did my homework in choosing a fitness watch with heart rate monitor. I ordered competing models from Garmin, Timex, Polar, and Suunto, to look them over closely and compare. Then I sent them all back but this one.
Someone pointed out that this Garmin watch is a little on the clunky side - that's true. I have a small wrist,and the watch part of it is long and flat and doesn't really fit nicely. They had to pack the GPS receiver inside the band. But no matter - with the band strapped tight, it stays put, and it's not so huge that people would say "What's that thing on her wrist?" It still looks like a watch. A funky sort of a watch maybe, but not a television set or anything.
I think you need to decide if you want GPS or not. I decided that yes, I really wanted GPS to measure my distance, because I run and jog and hike and travel quite a bit, so my routes are always changing. In my ideal world, I'd be able to pop up a map on my PC and see my route, and have a table showing all my workouts and how many miles they total, in running, biking, etc. I could finally answer the folks at the running store when they ask how many miles are on my running shoes.
I ended up with this Garmin, far and away the best choice for just what I wanted. All the other GPS solutions were separate strap-on-the-arm ones that contain AAA batteries that need to be replaced every 12 hours of operation - ouch, costly. Even with rechargables, it would be a hassle to be always taking them out, plugging them into the charger, putting them back in the arm-band-GPS unit. The watch on those other devices was just a receiver for the arm-unit. Granted, it meant that their watches could be a little smaller ... I really liked the design of the Timex the best, and the Polar was small too. But who wants to carry a clunky thing around their arm? That's one more thing to pack or lose, more batteries to buy and fuss with, more parts to break... forget it.
I also was swayed heavily by the Garmin software and tight integration with the PC and mapping software. None of the other brands, as of this writing (January 2010) had anything near as easy. Polar excels at fitness tracking, but not the mapping part. Timex and others require third-party mapping solutions that you have to manually upload and integrate with. Only Garmin had a simple plug-and-play solution. Plug in their little included USB "ANT Stick" (like a little thumb drive), and bring the watch near, and it automatically receives the data the watch stored from your workouts, loads it into your Garmin fitness/mapping program, and you can see all your stats and your routes etc.
I also liked that this unit is one of the few that tracks altitude, so you know not only how many miles, but how much total up and down you went (cumulative). It can display the data on a chart with any paramets you set, for example you can see the actual altitudes of your run along your route. That is so cool!
Other people trashed this unit because the bezel-touch operation is a hassle. One guy made the point that he just locks the screen into a view before his run starts, so he doesn't hassle with the touch thing going haywire. That is the perfect solution, and it's what I did too.
So with this Garmin watch, you only have to remember two pieces: the watch, and the charger. The charger clips right onto the watch to rejuice the battery inside. It ships with conversion plugs for international outlets.
Here's a tip that isn't clear from Garmin's specs: the GPS can be turned on or off. With the GPS on all the time, the watch will run out of juice after about 8 hours and will need to be recharged. With the GPS off, it lasts almost 2 weeks. It works like a normal watch, tells date and time, etc. Heart rate monitor. Etc.
I was worried that this watch wouldn't work if you, say, went out in the morning for a hike, stopped for lunch, continued hiking... 8 hours wouldn't be enough. The simple solution is to turn off GPS when you don't need it, and your battery will last as long as you need it.
So, if you can afford it, this one is the only way to go, if you want GPS. I've had it a month, after handling all the others, reading their manuals, etc., and settling on this one. I'm super happy with it and love Garmin. Next generation will be even better, when they fix the bezel issue and get the watch to be even more watch-looking, but this is miles ahead of the competition as is.
** Update - I've now had this model for almost two years, and still think it is fantastic. A few things I learned - The link to mapping software works great, I have two years' worth of running/biking stats and I can click on any single run to see the route. Since I travel a fair amount, it's a great memory of places. It's also great when I go to the running store for shoes and they ask "how many miles are on the pair you're wearing now?"
It also has a handy feature where you can set a starting point, such as the parking lot of a hiking area, and then once you're completely lost, have it point the way back - you get an actual arrow pointing and a distance indicator of how far away you are from that point. It's kinda buried in all the menus, so not something you'd be able to find quickly unless you did it regularly or had the user guide right there, but I used it twice and found it a comfort knowing that, even if I got lost, I wouldn't be lost.
It is also easy to switch between running and "multisport" modes, which means you can bike and jog and keep those stats separate. (That way, you're not apt to get impressed with yourself for running 20 miles, when in fact that day you were on a bike.) There is also an optional setting (that was delivered through a firmware update a year after I bought it, and probably is pre-installed on newer ones) that will detect if you've stopped moving for a given period, say a minute, and it will put the tracking to sleep till you start moving again. That helps you track your pace better if you have to stop for some reason and don't want that averaged into your overall time.
I have to mention that the wrist band closure is a bit of a hassle, if anyone from Garmin is reading. It has a little lock to keep the end from flapping, but in fact, it's really hard to push the locking end through the little hold-down. Just a wee bit of hassle, hardly worth mentioning. Everything else I said above is still the case. It's a great tool.

A Gadget Geek's Fun New Toy
I'm a new runner and after running the Shamrock Shuffle in Chicago this year, I think I'm addicted. I even registered for the 2009 Chicago Marathon, I still can't contemplate running a full 26.2 miles. But if I'm gonna do this, I'm gonna do this right. Running on nearby trails, I never really knew how far I've run or what my pace was (there aren't any mile markers). I wanted a way to track my distance and pace. I have friends that own both the forerunner 305 and 405, and I was impressed on how accurately they tracked distance and pace. I researched the reviews on both, and even though I like the looks of the 405, I was leaning toward the 305 since it's half the price and the reviews were much more positive. However, I couldn't get over the notion of looking like I'm running with a computer on my wrist.
Along came announcements of the 310xt and 405cx. Initially, I was set on getting the 310xt because of it's large screen and waterproof capability. However, it wouldn't be released till mid May and that model wouldn't even include the HRM. Originally I thought the 405cx wasn't available until mid May also, according to Amazon's 405cx preorder. But to my surprise, I found it available for free overnight shipping from the Clever Training website for 369.99. I got mine for 314.95 with free ground shipping, so do your research and you might land a "premium" deal on this heart rate monitors in USA ;-)
I'm getting side tracked here, I decided on the 405cx because I was hoping Garmin would have ironed out all the flaws of it's previous iteration. I've never owned the 405 or 305, so I can't say how much better the 405cx is. After reading the 405 reviews, a few complaints caught my attention:
- Poor satellite reception
- Clumsy bezel interface
- Locks up when sweated on
- Inaccurate heart rate monitor
1. Satellite reception is excellent. It's able to track satellites indoors! (though accuracy is degraded)
2. The bezel interface, although very sexy, is a pain in my arse to use. It's overly sensitive at times and not in others. Lock it often. It's going to take some time for me to get use to. Oh well, it's the price I have to pay for sexiness...
3. In the 2 days I've had this unit, it's never locked up on me. I want you to know, I sweat profusely to the point where it looks like I just took a shower (I wish I was exaggerating, but I'm not...). I don't just sweat when I'm working out either, sometimes I sweat sitting idly in a chilly room. It's so embarrassing during meetings! So trust me, sweating does not cause the 405cx to lock up.
4. The heart rate monitor is superb. This is my first HRM though, so maybe I don't know what I'm talking about. But it doesn't spike to 200 bpm or drop to 20 bpm like the treadmills in the gym do, so I'm happy. On a side note, the 305 loves the HRM that comes with the 405cx. The one that comes with the 305 is utter garbage, it stays at 65 bpm regardless of what you do. It was probably defective, but it's something to think about for anyone thinking of getting the 305 instead.
This review is getting really long, and I need to get back to work. Garmin Connect is the online software that manages all your running data. Use it, it's hot. Just be aware, at default all your activities are shared with the Garmin Connect online community (think of what you put on your descriptions). I love how you can "play" your run on Google maps. It's hard for me to explain, check out this link for yourself
[...]
Please don't make fun of my slow pace, I'm a new runner! Here's a tip before I end this. You can delete activities. Just click on the red "x" next to the pencil and lock. This was a little frustrating until I figured it out. Good luck deciding on a watch, I hope it makes your runs more enjoyable. It does for a gadget geek like me.
