A Terrible Disappointment - Stick with the 305
As a long-time user and fan of the Garmin 305 the Garmin 405 was a product I was looking forward to for months as I was excited to see the next generation of the 305 I have enjoyed so much.
I could not be more disappointed with the result.
The Garmin 405 is a classic example of a good product concept and clever design gone horribly wrong as the Garmin team focused on form (looks) clearly beat out the folks worried about function. The watch looks fine (great for a HRM/GPS watch so so for an everyday watch) but in terms of actual purpose-built functionality it is terrible. There are multiple reasons for this which I will outline below.
(1) Useless when wet (yes that includes sweat). The fact that you cannot toggle between screens or do anything with the bezel while the device is wet should have caused the designers to toss out this novel touch sensitive concept and stick with what works. Instead they decided to go with a neat design concept that works great when the salesperson is showing it to you at the store but will provide endless hours of frustration when you are out running and just want to see your heart rate. This is my first bullet point because it is the best example of the type of design failures that make this a terrible device.
(2) Use of built in functions/screens - The makers carried over the capabilites of the Garmin 305 and added a virtual training partner functionality but the display can only show three fields at once and the fields themselves are too small for good viewing while in motion (ie running). Cycling between the displays is easy to do while sitting on a couch even fun when you run your finger along the bezel but when you are out running you quickly realize that it is very difficult to accomplish anything with the device. With the 305 if you wanted to change fields on the fly you could manage to do it while keeping a reasonable pace. With the 405 you need to press buttons and run your finger along the bezel to switch fields - again great on a couch nearly impossible on a run.
(3) GPS Accuracy. I have traded messages with people who disagree and I will say that I sometimes have great accuracy but have also had multiple experiences where the accuracy of this device is off by so much as to make the pace and distance benefits of a GPS useless. The best example is running a measured mile with typical neighborhood street tree coverage and having the device show I went a total of 0.70 miles (the 305 on the same stretch showed 1.01). I have had this happen multiple times in various locations and therefore have stopped using the watch in races when I want to know my true pace and distance (I am using the 305 again).
(4) Silly things that might (or might not) drive you crazy - There are two buttons on the Garmin 405 - both on the right side of the face as you look at it. These buttons perform some useful functions including locking the bezel so that you can wear the device in a non-GPS mode and avoid running down the battery needlessly while still using the device as a watch. The problem is that if like me you actually own a daily wear watch and when you travel you prefer to put the 405 in your bag or suitcase having the two buttons on the same side means that if they press against anything they will unlock the bezel and the GPS will start running (or try to). The result will be a dead battery when you pull it out of your bag. It may seem minor but pulling the 405 out of your bag after you arrive and want to go for a run only to see it is dead again and again is annoying. The positive offset is that the watch actually charges at a pretty decent speed. Oh yes and when the battery does in fact die you will need to go through all of the intro screens again to get it going which will sometimes freeze on you (check message boards for solution to this as some people have posted them).
Overall this is a terrible product and if you really want to get a GPS enabled running device I would highly recommend you buy the Garmin 305. It is much cheaper and while it does not look as good the size will not bother you after a couple of wears and it will work flawlessy for you. I suspect they will eventually correct the failings of the Garmin 405 but until they do it is not a good use of your money.More detail ...
