Garmin Forerunner 305 GPS Receiver With Heart Rate Monitor
February 5th, 2010 | by Paul Julian |Amazon.com Review Just when you thought Garmin had cornered the market on powerful, affordable, and effective wrist-mounted GPS devices, here comes the Forerunner 305. The release of this device is a major achievement from a design and technology perspective. This isn’t just marketing-speak; the Forerunner 305 is the most accurate, most reliable wrist-mounted performance and GPS tracking tool we’ve ever tested. Yes, it’s that good. While no device this compact can do everything (yet), the 305 pushes the boundaries of what is possible from something strapped around your wrist. The 305 model includes wireless heartrate monitoring and it can also be connected to Garmin’s wireless bicycle speed and cadence sensor.
GPS Performance
The big news about the Forerunner 305 is that it features an integrated, high-sensitivity SiRFstar III GPS receiver. What does this mean? It means that the 305’s ability to both track, and maintain a lock on, your position is better than anything before it. After an intial battery charge, the tester had the 305 on his wrist and was tracking speed and distance with GPS satellites within 3 minutes. The next time we used the 305, satellite acquisition was nearly instantaneous. A run through dense trees didn’t faze the unit either; tracking remained true and steady. Performance on a bike was equally impressive. Whatever witchcraft has been cooked up by the designers of the SiRF technology, we like it!
Computer Connectivity and Software
Garmin has been outfitting their devices with USB connectivity for some time now — a welcome move for those who struggled with serial port connections in the days of yore. Thanks to USB, the 305 integrates seamlessly with the Training Center software and we quickly had workout history uploaded and stored on the computer. Not only does Training Center–which is compatible with both PC and Mac–make it easy to track your performance, you can graph data such as heartrate alongside your speed and distance. Over time, this is a great way to view your fitness levels increase, and it also helps you see what types of workouts are necessary to strengthen your weaknesses. For instance, if you see your heartrate begin to spike after a certain distance, you know you need to increase your endurance workouts to train that area of fitness.
Design
The 305’s design is a radical departure from Garmin’s previous generation of wrist mounted GPS devices, which reached a pinnacle with the Garmin Forerunner 301. While the 301 delivered accurate heart rate monitoring, good performance tracking, and decent GPS reception, it didn’t quite deliver in the design department. The form factor was bulky and wearing it wasn’t much different than duct taping a full-sized GPS device to your wrist.
Not so with the 305. Garmin’s engineers obviously burned the midnight oil and have come up with a waterproof design that, while certainly not as small as a sports watch, feels just as comfortable. The curved casing allows the unit’s antenna to face the sky when you’re running, while the widescreen display is perfectly positioned for viewing when you need it. And the display certainly deserves a few kudos. While it’s smaller than the display found on previous Forerunners, its resolution is far higher, offering incredible clarity and crispness.
Training Functions
The 305 is first and foremost a training tool, and its ability to organize a ton of data types into a user experience that is intuitive and simple is no small feat. Whiz-bang technology aside, if you can’t use it and make it a natural part of your exercise routine, it’s worthless. When it comes to these factors — and here’s the take home message on the 305 — this device is successful where many other devices fail.
The heart and soul of the Garmin 305 can be found on the data screens, which give you real-time information about all aspects of your workout. In fact, the 305 can display a dizzying array of data, such as calories burned, distance, elevation, grade, and heading, as well as multiple lap and pace modes. The 305 adds the ability to track heartrate, lap heartrate, average heartrate, and heartrate zones via the included coded heartrate chest strap. With the purchase of a separate wireless cadence and speed meter, you can also track bike performance data.
Thankfully, the device makes it easy to define how much or how little data you want to view during a workout. You can arrange the data that’s most important to you and then make that data appear front and center on the device. Indeed, within a few minutes of skimming the manual and fiddling with the device setup, you’ll have your most important data displaying just the way you like it. The ability to display heartrate is a big plus, too, as it’s a fairly good indicator of excercise output, fatigue, and fitness level. The 305 has all the heartrate functions you’d expect from a full-function monitor, including the ability to set target zones and alerts to maximize the effectiveness of your workouts.
