Whether you're training for a world-class event or just want to get data from your daily workout, the Garmin Forerunner® 405CX heart rate monitor will help you get the results you desire.

  • Forerunner 405CX features a new advanced calorie-consumption formula that calculates calories burned based on micro changes in the user's heart rate during aerobic activity
  • Developed by excercise scientists and world-class athletes, the formula more accurately calculates calories burned than previous methods
  • Forerunner 405CX comes with 3 wristbands to accommodate nearly every wrist size; the 2 included form-fitting webbing wristbands comfortably fit large and small wrists
  • GPS satellites accurately calculate speed, distance and pace information; GPS receiver provides rapid first fix and is sensitive enough to acquire signals under cloud cover
  • Navigation capabilities let you mark locations, find locations or navigate back to the starting point
  • Chest-strap heart rate monitor helps you train in your target zone to optimize performance
  • Compete against the Forerunner's Virtual Partner® to help improve your times; simply set time, distance or speed goals and race against a runner icon on the display

  • Data can be analyzed by downloading free Garmin Training Center® (GTC) software onto your computer or by using the Garmin Connect community website
  • Garmin Connect community website tracks your time, speed, distance and calories burned; store and share routes with other Forerunner users on the website
  • Website also allows users to categorize and design workouts based on activity—prior workouts can be saved by day and week designations
  • Wireless data transfer can be used to send courses, goals and workouts from your computer to the Forerunner 405CX before heading out for a jog

  • Forerunner 405CX will store up to 1,000 laps and 20 hrs. of exercise data, which can be uploaded to GTC at any time

Good mix of features but...

Rating:****
I've used the Garmin 405cx for a month. I knew that I wanted a new heart rate monitor and the GPS in this device was a bonus.

I like:
- that you can customize the training screens to show whatever you want. For instance, *I* decided that I wanted the calories as the main display with distance and hr in the sub-display.
- that I can see where I've been in google earth. It's a little gimicky but fun to look at especially after I've done a new hiking route.
- that there are a couple of alternative (and free) applications to view/slice/review the data. Most notably SportTracks.
- that the watch looks like a watch. Not a netbook on my arm.

I don't like:
- the touch bezel which is finicky with moisture. If you aren't sure then wet your hands with water and try it out in the store.
- the elevation metering seems inaccurate. I work out in the gym and it has been registering >1000 feet in elevation gain. I see a similar inaccuracy sometimes when hiking routes along cliff faces and gorges. I guess the gps doesn't know if I'm at the top/middle/bottom of the valley wall.
- the power charging clip. It's okay but a little clunky. When it's clipped on, the watch wants to lay on its face which I suspect will lead to some scratches and scuffs.

I wish:
- Garmin's PC training software was as robust as SportTracks. The plugins and open API seem to make ST a lot more robust and extensible.
- the 'Return to Location' feature was a breadcrumb type where I could backtrack along my original route out.
- the screen material was not plastic. To prevent scratches, I've coated it with a screen protector film for a mobile device. Just extra hassle.
- the watch came in another color like black or dark gray.

Overall
I think this is a very good product if you are a outdoor and fitness person. Having a viewable data is pretty interesting especially if you like to know how your performance is per lap/mile and during climbs.

Excellent training and tracking tool.

Rating:****
Initial set up took less than 10min and the learning curve is low for most people used to todays gadget laced world.There are two software options to chose from. The stand alone Garmin Training Center and the web based Connect.Garmin.com(will replace [@]) The stand alone software needs significant user interface upgrade. There are no maps included with Training Center, you need to own Topo to create routes at home or run/cycle the route first and then modify it later. It has many workout templates that can be modified to create a variety of training programs. Garmin is however migrating its MotionBased.com site to the new Connect.Garmin.com site. As of this review the site also needed some minor improvements, mainly the ability to create advanced workouts, which Garmin says will be implemented in time as Motionbased.com is migrated over. The user interface is much smother than the stand alone software which is a modified version of Garmin's existing software made for early hand held GPS devices which has never been given a face lift.The user interface of the wrist unit is still the same but the sensitivity has improved over the original 405. However the 405cx may still aggravate those who sweat intensely or are looking for multi-sport triathlon waterproofing. The new 310xt may soon fill that slot for Garmin. Heart rate bands from other popular manufactures will not work with the wrist unit.

Compare Garmin Forerunner 405 and 405CX
