Manufacturer's Description

The Forerunner 405CX is a sleek sportswatch that tracks your time, distance, pace and heart rate, then wirelessly sends the data to your PC for later analysis. The 405CX features heart rate-based calorie computation and comes with a fabric wrist band option suitable for smaller or larger wrists. With a high-sensitivity GPS receiver and HotFix™ satellite prediction, the Forerunner 405CX locates your position simply, quickly and precisely and maintains its GPS location even in heavy cover and near tall buildings and trees.

Training features

Loaded with serious training features, the Forerunner 405CX continuously records your time, distance, pace, calories burned and heart rate. Each workout is stored in large internal memory (1000 laps) so you can review and analyse the data to see how you've improved. And advanced training features will challenge you to step up your pace — race against Forerunner's Virtual Partner® to improve your times, or set up interval workouts without having to circle the track. You can even download recorded courses to compete against previous workouts. To use the watch, simply tap the touch bezel to change screens without fumbling for a button.

Track Heart Rate

Forerunner 405CX comes with a flexible, wireless heart rate monitor to help you make the most out of your training. The digital heart rate monitor continuously tracks heart beats per minute and uses your heart rate for advanced calorie computation, so you know how many calories you're burning. Train in a certain heart rate zone to improve your fitness level or compare your pace and heart rate to past performance on the same run.

Share Workouts Wirelessly

With Forerunner 405CX, you can share your locations, advanced workouts and courses wirelessly with other Forerunner 405 users. Send your favourite workout to your friends to try, or compete against someone else's recorded course. Sharing data is easy: just select "transfer" to send your information to a nearby device.

The wireless foot pod clips onto your laces for easy removal and automatically turns on when you start moving. Or pair your Forerunner with an optional speed/cadence bike sensor to track the speed and distance of your cycling workouts.

The nüvi 1210 is an ultra-thin, pocket design, affordable and simple-to-use sat-nav with mapping for the UK and Ireland.

    Strongly recommended step up from old models5
    Having just bought the 405CX I found the lack of user reviews deeply frustrating. Having had the watch for 2 weeks I thought I would share my experience.
    I formerly owned a 305 and my big concern with the 405 was the reported difficulties in picking up satellites (as a result of the smaller design). Well the 405CX has certainly resolved these issues. I'm guessing the kit remembers where you tend to be because it catches a satellite even in areas that would have been a total no go with the 305 (like in the shadow of tall buildings). This morning's run got a satellite connection in 5 seconds (really!) Combine this high sensitivity with an ability to save locations and the GPS functions are better than ever. Other reported issues were the wet sensitivity of the bezel. Well it certainly works when wet hands touch it - although I've yet to go out in a downpour this bodes well for me. I tend to leave it on a single screen so changing the reading isn't likely to be that important.

    Having been an enormous fan of the old model I bought this (more expensive) upgrade only when my old one was stolen. However having made the purchase I would recommend others to do the same - it really is a delight. The battery meter tells you specifically how much energy you have left so you're unlikely to be caught short - and the battery is certainly no weaker than the old model. At least now you can assess whether it needs 10 minutes charge before you go out - rather than the guessing game of the past.

    Runners - you'll love it. The old model was the best bit of kit I'd ever bought - the 405CX is considerably better. A strong recommendation.

    Quality sports watch with excellent features.5
    I write this having owned both Sunnto and Polar sports watches in the past. I've owned the Garmin 405CX for a month and used it both for running, circuits (outdoors) and in the gym. Overall I would highly recommend this piece of kit, it has exceptional features, excellent data capture and a great on-line (or PC based) inter-face to which you can download your data, analyse and share it. The bezel takes a little getting used to but no more so than an iPOD. The positives and negatives are as follows:

    +VEs:
    - Excellent in-built GPS that has no trouble locating satellites in urban and non-urban areas. It even has a track back function should you get lost! Doh!
    - Good heart rate monitor (standard chest strap).
    - Multiple data pages that you can customise to show multiple permutations of HR, pace/speed, distance, averages.
    - Virtual training partner - a nice feature to help you train or run.
    - It comes with both standard and velcro watch straps. I prefer the velcro.
    - Garmin provide really good user videos on their website that talk you through the multiple features; a real benefit as I get bored reading manuals!

    -VEs:
    - I'm still getting used to having to charge the watch every few days but its no more inconvenient than charging my iPOD.
    - I'm dubious about its water resistant qualities. A perfect watch would offer decent water resistance (up to 10M) but I'm just not sure how far to test this!
    - A little more choice in colour would be nice.

    All in all I would highly recommend this, if your into fitness training and you enjoy analysing data ( and sharing it) then this is the watch for you.

    From a beginner5
    Excellent product. I have just taken up jogging and it really is useful to motivate and guide. You don't have to be a super fit athlete to get maximum benefit out of it. It also has a bike mode. The heart rate monitor is non-intrusive. It fits comfortably on a lady's wrist and I like the look of it. The watch automatically downloads into my PC. The calorie counts are fun too!
