Garmin Forerunner 405 – The Review

As you all know, I think the Garmin Forerunner 305 is the best thing since sliced bread but I’m so fickle it’s taken barely a thought for me to stick it on ebay and swap it for the new version – the Forerunner 405.

I’d like to say the new and IMPROVED Forerunner 405 but is it?

Reading the spec list it’s hard to see where Garmin made any attempts to improve on what had gone before, they missed out by not making it fully waterproof and therefore tri suitable, for example. Instead they appear to have simply repackaged the existing 305 as a sports watch that can be worn all day with the bonus of a nifty touch sensitive bezel control.

Out of the box, I decided I liked the look and feel of the watch very much. Garmin put a lot of effort into design and the strap closure is ingenious, a big improvement on the 305 which kept coming loose, snagging on my clothing and risked falling off. A minor point maybe, but Garmin are big on the little details.

The watch charged fully in 3 hours by the use of a strange bulldog style clip that slips snugly into a couple of recesses on the back of the watch. Another neat design but I fear it is just going to prove an inconvenience. With the 305 you uploaded data to the PC by slotting it into a USB docking station and it would charge at the same time as uploading. I’d leave my device in for a few minutes longer and thereby ensure I always hard a fully charged unit. With the 405, uploading data is automatic and will occur while the watch is still on your wrist, which now means I’ll have to remember to charge the unit separately.

In standby mode (ie time display only) the watch will supposedly last 20 days, although I’m down to 89% charged after 1 day so I doubt it will last much longer than a week. When used in active mode the battery life is expected to be in the region of 8 hours. So that’s another charging gizmo to be added to my pile of wires under my bed.

I thought the software was a bit of a faff to install, it didn’t happen automatically and I had to hunt around to see what it was that needed to be loaded up. It comes with Training Centre but after installing it I immediately removed it again because I remembered how pants it is. Instead I’m using the ANT uploader linked to Garmin Connect which is quite a neat online training log.

Setting up the watch is a doddle and it takes you through the process quickly with a mini tutorial that teaches you the basics of the bezel control. Basically:

  1. press and hold on the relevant label to access either time/date, training, menu or GPS functions
  2. slide around the bezel to move through menu options
  3. tap to accept
  4. tap in two separate places to activate the backlight

Forerunner 405 Virtual Partner

All very easy really. I had no problems using the bezel on the run, not that you need to use it much, you can tap to nudge the screen to a different view and in virtual partner mode you can increase/decrease the pace of your partner by sliding the bezel. I’m particularly fond of that feature as it means I can ensure I win every race now.

I’ve heard a few people fearing that accidental touches of the bezel would mess up the data but they shouldn’t worry. The start, stop and lap functions are all controlled by the big side buttons. Pressing the bezel during a run just alters the view – not a big deal. I haven’t tried it with gloves but as long as they aren’t massive affairs it shouldn’t be a problem.

For my first run I decided to set up a simple interval session, run 90 secs, walk 60 secs. I know that’s lame but I’ve got a cold and needed the walk periods to retrieve my hankies and have a good blow! Easy enough to setup, you don’t even need the manual. Features and settings are much more intuitive on the 405 than with its predecessor.

The intervals were well “signposted”, I was given a 5 second warning of loud beeps followed by a clear “chirrup” that marked the start of the next interval. I didn’t miss one and I appreciated the warning. A good feature.

forerunner-405-3

I personalised the display I wanted to see on the run, you can choose upto 9 features to be displayed on 3 screens. On my main screen I had pace, time and distance and I accepted the defaults for the other screens. It’s well worth playing around though as there appear to be some great features. This is available on the heart rate screen for example and shows progress within your heart rate zones.

I had set the screens to auto scroll but will turn this off for the next run, I think it is more convenient to control the screen I view by tapping the bezel, that way I don’t have to wait for it to get around to the bit I’m interested in.

Back home, I was just unlocking my door, when the watch beeped to say it was uploading data. By the time I’d staggered through the hall to the laptop, my stats were already displayed on the Garmin connect website.

As a simple everyday watch its functioning fine, but I would have preferred the power save mode to be the time and date screen, not just the time display. It’s a fiddle unlocking the bezel so I can access the date feature. Its also quite chunky so if you have a small wrist you are unlikely to find it very comfortable and it will probably overhang a little. I don’t have a small wrist though so I’m alright Jack.

I’m pretty pleased with it so far and think there are clear signs of improvement, I’ll be scrutinizing it further though and am particularly keen to see if there are any improvements with the speed in which it locks on to a GPS signal.

*UPDATE 22 July*

If you are in the market for a GPS running watch, this is the leader in my opinion but as for pros and cons of the 405 vs 305 here goes:

Pros:

  1. Faster GPS pick up, I’ve seen responses within seconds even when I’m moving but it is still not perfect. In heavily built up areas of London the reception is slow.
  2. Louder volume on the beep/alarm so you can actually use it for interval training.
  3. You can wear it as a watch all day – should last about 2 weeks before charging.
  4. There are a lot of new screens available and it is very easy to adjust – more intuitive than the 305.
  5. You can adjust the speed of the virtual training partner while you are on the run.
  6. Easy wireless upload.
  7. Smaller, lighter and more inconspicuous.

Cons:

  1. Sometimes the bezel seems to be a little unresponsive, so if I tap the edge to get to a different screen it may not respond, so I tap again and eventually it goes crazy and skips thru multiple screens.
  2. Because I don’t want the useless training centre on my computer I have to be quick if I want to upload the run to Sportstracks, as it doesn’t seem to save the file on my pc.
  3. When the watch gets wet – say from splashing at a water fountain – the bezel goes nuts and the forerunner generally doesn’t respond. Wipe it dry and its back to normal again. See comments 22-25 and here’s a link to one bloggers frustrating although amusing communication with garmin about the issue.

Not many cons really but maybe I’ll to them later.

The Garmin Forerunner 405 currently retails at Amazon for just under £210: Garmin Forerunner 405 with Heart Rate Monitor and USB ANT stick – Black

Hard for me to say really as I have a distinctly chunky wrist. It is smaller than the 205 but still very large by watch standards.
The Polar RS200SD is a very good alternative – reasonably sized if you don’t the GPS functionality. It measures distance via the footpod and is and excellent sports watch.

Hi, Just recieved 405 and still getting the hang of it….all the distance info appears to be in k,s is it possible to have miles as the default setting…if so how do you do that…any help much appreciated..Ta

Darrell April 6, 2009 at 4:21 pm

Thanks for that…to keen to get out running and not paying attention to detail….had the same problem with the the new tv and washing machine…really do need to read the instructions properly…off out for another run and really going to enjoy it this time knowing it’s in miles….really feel that you benifit more if you use miles as 50 miles a week in your diary is so much more motivating than 50 k’s…..off for a paper…c…u…later…Kev

Hi

Just wondering if anyone has a problem with battery life. It seems if in GPS mode it only lasts 6hours riding time & seem to be recharging every second day eevn with just an hour of active use. Is 6-7hrs all you get? also when the battery dies does it still keep the data as last time it recorded time & distance but lost altitude & pace etc. Cheers

warriorwoman April 14, 2009 at 6:45 pm

Garmin only claim a battery life of 8hrs in training mode and that is bound to be a little optimistic.
Charging every other day seems a bit extreme though. In power save mode my lasts for about 2 weeks but that is without use.
I think the wireless transfer highlights the battery life problem. With the 305 I used to sit it in the USB cradle to upload the data and charging happened at the same time. Now I have to think of the two jobs separately and one or other rarely gets done til its critical.

Emma April 20, 2009 at 3:06 pm

Hi all, I too am trying to decide between the 305 and 405 – I heard that the 305 actually has a map screen whereas the 405 doesn’t – is that something that people feel is missing from the 405?
Cheers
Emma

Darrell April 20, 2009 at 4:27 pm

Hi, I can’t see a map mentioned in the manual of the 405 but here’s the link to it for you to check as well and perhaps familiarise yourself with it’s features and functions.

http://www8.garmin.com/manuals/Forerunner405_OwnersManual.pdf

I have the 305 and it’s excellent, probbaly a good price too now. The 405 has had some issues mentioned regarding it’s sensitivity to water/sweat and also that the bezel is fiddly to get up the screens you want mid run. On a plus side, the 405 has a vibration alert which will be useful if you run to music as I rarely hear my 305 beep to tell me the pace of the last lap, etc.

I’d recommend Sporttracks over the included software every time too, as Training Centre that comes with it is awful in comparison.

Firstly thank you for all this information. I’ve been trying to get a 405 for ages now (as a present) but my girlfreinfd just doesn’t seem to why this would be the perfect present.

as a result I’m considering paying for one myself. I’ve been using a £5 stpwatch for the last two years and until I read this review have not been that bothered. Now after reaing this I definately want one. However, I am currently training for the Comrades next year and the 405′s battery life will not be long enough for the race. So is it possible to turn off the GPS and therefore extend the battery life?

Obviously for anything up to marathons I could use all the functions but only 8hrs for ultramarathons is not very good.

Thanks again for a great review.

Darrell May 22, 2009 at 5:58 pm

Hi Ross,

I’m pretty certain that you can; on the 305 that I have you can tell it that you’re indoors and it switches off the GPS. Check out the manual here to be sure though:

Hi there,

Forgive me if this has already been discussed.

I think I’m going to buy a 405 however I’ve heard it transfers data to your pc through wireless capabilities. What means does it use to do this. I don’t have Bluetooth technology on my P.C.

Any information would be extremely useful.

Thank you for your time.

Warriorwoman June 5, 2009 at 9:40 am

No need to worry, Garmin ship everything you require in the box.
It comes with a little USB dongle that provides the wireless link.

Bixente August 25, 2009 at 10:11 am

I love this watch but it just goes mad when it rains. Again this morning I was running a 10 miles and it just stopped suddenly after 4 miles because of the rain then it went crazy switching from one mode to another. Really annoying.

If your fingers are wet as well the bezel will go mad.

Jarrad October 8, 2009 at 8:39 am

I bought this watch as a gift for my wife. It is clearly designed for men and did not fit her, there is a lot of adjustment in the strap but the moulded body meant it was simply too large to fit on a small wrist. I’m sure its a fine watch but it doesn’t fit everyone!

Jim December 14, 2009 at 4:07 pm

I found a way to use my 405 in the rain and be able to get the bezel and buttons to work quite well – does not go nuts and unresponsive.

I put fasten plastic over the bezel so rain and moisture from fog doesn’t get on it.

I cut a plastic sandwich bag open and in half. Then I wrap the plastic over the watch and strap. The I use tape on the back to hold the plastic in position. So I end up with a protective cover that allows me to touch/tap the bezel to change views. And the view stays where I want it.

Maybe Garmin can develop a better bezel rain cover.

Kate HOY February 21, 2010 at 5:57 pm

I’m afraid that sandwich bag story made my mind up! My beloved 305 proved not so rain-proof last friday – one week out of the guarantee period :-( I have a marathon in two weeks time and feel lost without it. BIG question – upgrade to the 405 or stick with what I know. It looks like the 405 doesn’t have the mapping features that I use – i plot a course on mapping software, convert the file to Training Center and then upload it to my 305 and head for the hills following the arrow. Without this I’d never make it home, so its essential. Also not sure about the tricksy bevel sounds like gadgetry that is yet to be perfected.
Thanks for the great review and some really useful info.

warriorwoman February 23, 2010 at 10:55 am

I’m going to be in the market for another GPS unit soon and I don’t think I’ll go back to the 405. I will either stick with the solid reliable 305 unit or, as the prices seem to be dropping a bit I might go for the waterproof version – the 310XT. This looks to be a very useful piece of kit.
Good luck with your marathon.

Kate HOY February 23, 2010 at 11:26 am

Managed to fix my 305 with a bit of DIY, a screw driver and a hairdryer. Perhaps not recommended practice but its working and I’m a happy camper! It looks a bit more rugged now, which has got to be good for my image, no? After my rain episode I would seriously consider the waterproof 310XT as my next purcase.

Dave May 8, 2011 at 8:45 pm

Although im a Garmin fan, i am a little dissapointed with this watch. Too much style, not so good function. I think they tried to sell the “iPhone sensation” and misebraly failed. Thats why they made the 405cx so fast.
Based on the functions this watch provides, id highly recommened the Garmin Forerunner 110 review its easy to use, made just for runners and it still looks good…plus no touch bezel!!

Darrell May 9, 2011 at 6:21 pm

I’m sure the 405cx is good, but I’d definitely recommend the Forerunner 310XT (reviewed here: http://www.warriorwomen.co.uk/2010/07/07/garmin-forerunner-310xt-the-review/) which is far better, faster to lock onto satellites and waterproof too!! Another thing regarding Garmin GPS products is that Garmin Connect is now far more user friendly and works brilliantly with all Garmin GPS products, even easier with the ANT+ compatible products enabling automatic wireless uploads.
