Amazon.com Product Description The successor to the Garmin Forerunner 301 is here, and it's better than ever. Weighing in at just over 2.5 ounces, the Garmin Forerunner 305 breaks new ground in terms of comfort, style, and performance. Totally redesigned, the 305 gives outdoor athletes and runners real-time information about speed, distance, pace, and heart rate on a device that's easy to use and amazingly compact.

The Forerunner 305 features the powerful new SiRF GPS navigation chip for supreme accuracy, even under tree cover and between tall buildings. A coded chest strap heart-rate monitor prevents unwanted interference from other devices. View larger.

The unit's GPS receiver is designed to face towards the sky when you're running.

A more watch-like design makes it far easier to use and wear.

Plus, the 305 is engineered to help folks train better and smarter. Training assistant tools, various distance and time alerts, and bundled Training Center PC software combine to make the device an essential part of any athlete's training program.

The 305's digitally coded heart-rate monitor--which is worn as a chest strap--sends heart-rate data to the device so you can see whether you're training too hard or not hard enough. Alerts for pace, distance, time, and heart rate are also available. Additionally, the unit tracks speed, distance, pace, and calories burned. Meanwhile, a course feature lets you race against previous runs in order to improve your time or just compare heart rate and pace data at every point of the way.

The 305's easy-to-read, 1.3-inch display has been integrated into a sleek and stylish form factor that is definitely a step up from the larger and more cumbersome Forerunner 301 model. Indeed, the 305 looks and wears like a stylish sports watch, and it's more carefully designed to meet the needs of athletes. The design also positions the antenna with an optimal view of the sky. As an added feature, the case is water resistant to IEC 60529 IPX7 standards (can be submerged in one meter of water for 30 minutes).

Accuracy is the name of the game with the 305. The vastly more accurate GPS antenna and receiver, which uses an advanced SiRF chip, offer much faster satellite acquisition times. Plus, the unit can hold a fix in places never before possible. Gone are the days of losing a fix under tree cover or when running between tall buildings. All of these features add up to far more accuracy in recording and tracking your exercise data. And because the 305 uses GPS to track how far and how fast you're going, you never have to calibrate it. The unit also doubles as a basic navigator. Mark your starting point as a specific location, see your current position on the plotter display, and follow an electronic breadcrumb trail back to your starting point.

The 305 features a USB data connection and docking cradle for downloading your speed, lap, exercise time, and heart-rate data into Garmin's Training Center PC software. The unit stores up to 1,000 lap histories, which you can download to your PC for a detailed post-workout analysis. Plus, you can create and schedule workouts using the included software and download them to the unit. A rechargeable internal lithium-ion battery offers up to ten hours of battery life.

For additional post-workout analysis, the 305 is compatible with MotionBased software. MotionBased adds a new dimension to training and outdoor fitness that makes the analytical aspects of a sport more compelling and a lot more fun. You can upload data to MotionBased, a Web-based application that has partnered with Garmin. MotionBased provides in-depth analysis of your workouts, as well as online mapping and route sharing that will take your training to the next level. MotionBased automatically calculates time, distance, speed, elevation, and heart rate, and it displays this information through meaningful charts, illustrations, reports, and maps. With MotionBased, you can also race multiple instances of the same route to see how you are improving or to race other members of MotionBased. You can "virtually race" someone you don't even know.

If you like the features of the Forerunner 305 but don't need heart-rate monitoring, be sure to check out the Forerunner 205.

Product Description

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.Train indoors and still track your distance, pace and calories burned with the optional foot pod. This wireless sensor attaches to your running shoe and transmits distance and pace data to your Forerunner 305 so you can still use it when GPS reception is unavailable.

4.0 out of 5 stars Excellent workout tool May 3, 2006

By PAZMAN

I like this thing quite a lot. I've had it for about three weeks, and have used it on 12 workouts so far. I use it primarily for running, with biking a secondary usage. The main reason I wanted it was for the instantaneous readout of distance, running pace and heart rate, the latter needed for the speed work I want to do this running season.

The core functionality (distance and heart rate monitoring) works perfectly. There's none of the signal drops I've had with other heart monitors. Once the satellites are initially acquired, I've only had one dropout when I was outside. The initial acquisition of the satellites can be quirky and can take some time. The accuracy (according to the readout) is +/- 25ft, depending on how many satellites can be found. I've compared the distance measurement on the GPS with a known, measured distance on one of the trails I run on (the Chicago lakefront path). The GPS always increments a mile when I'm within 5 or 10 feet of the mile marker sign on the path. Well, I guess that's the least I should expect from a $350 GPS unit! Of course it's bigger than a normal running stopwatch, but that hasn't bothered me at all. The heart rate strap is also very comfortable and well-designed.

The display is crisp and has one outstanding feature: The information presented on the various pages can be completely user-customized. The default screen layout is rather poor, but in just a few steps I could replace it with the information I wanted to see while I run. There are almost 40 different data fields you can choose from for display. Examples: current pace, average lap pace, average run pace, heartrate, distance.

The only disappointment is the point-in-time (instantaneous) pace measurement: It varies wildly during a run. I see swings as big as +/- 3 minutes/mile. I'm a marathoner and I know my pace is fairly consistent during a run. I just looked at my run today, and according to the data the first mile varied from 5:57/mile to 12:06 mile. I suspect the problem is either in the averaging algorithm (too short a distance?), or in the uncertainty that results from different satellites coming in and out of view. The variations seem to get worse under tree cover compared with an open area. Luckily there's a lap-average pace that can be presented, and at least that value is useful and more accurate. The bottom line is that you can't look at the watch and say "right now I'm running 9 mins/mile". There is the ability to specify a pace smoothing factor, but I have it maxed out and still see the variations. The elevation readout also seems inaccurate, but that isn't important to me.

Upload of workout data to the PC software (Training Center) is transparent. The PC software is very good for presenting time/distance/pace/heartrate/calorie data. However the maps it shows are very crude. I've worked a bit with one of the online, subscription services (MotionBased). That looks really good and provides some additional functionality beyond the included Training Center software, although I still haven't decided if it's worth the $$$ yet for long-term data storage. MotionBased allows export to Google Earth, and it's tremendously cool to see your running path superimposed on a satellite image. You can recharge the unit through the USB port on your computer, although it's slower than using the dedicated recharger.

I had hoped that owning this device would prove motivational for me, and indeed it has. I can't imagine running or biking without it. Updating my training log is trivial now: Plug this thing into my computer, and it's done. My hope is that a future software update will do something about the pace calculation (maybe a few additional levels of smoothing?). If so, the Forerunner 305 would earn 5 stars+++.

Positives:

Flawless heart rate sampling
Great distance measuring and lap-average pace calculation
Seamless integration with a PC
Fully-automatic training log update
User-customizable display

Negatives;

Wildly-varying pace readout.

5.0 out of 5 stars Better than 405 & Polar...GOOGLE EARTH alone is worth the upgrade!!! May 27, 2009

By Y. R. Wu TOP 50 REVIEWERVINE™ VOICE

I use mine for cycling and running, the direct link to see your workouts mapped on GOOGLE EARTH is FANTASTIC!!!! (the included software is far more stable than the junk Polar included with their HRM's.

Heart rate strap with replaceable battery is coded and comfortable. It's better in my opinion than the Polar products (of which I've owned three)

This is much better than the Forerunner 201 which I previously owned (locks on satellites 10 times faster) and I'd avoid the 405 unless you really want to use this watch as a normal day to day wristwatch (check out the 405 reviews)

One nice feature is being able to customize the display screens. Another review criticized the 305 for the numbers being too small to read while exercising. I don't have an issue but would point out that you can significantly increase the size of the display by simply displaying fewer fields.

My only complaint is that it's easy to leave it on and run the battery down - which is a bummer if you're just about to work out. I wish there was an "auto off" feature which would shut it down if it detects no movement or heart rate within an hour or so. Fortunately, with Li-Ion batteries, as little as a 10 minute charge gives you enough juice for a 90 minute run.

If you've found this review to be helpful, please let me know!

5.0 out of 5 stars All I hoped for! August 28, 2006

By M. Leuzinger

With a few one-star reviews, I was a bit hesitant to order this. Now, after two weeks of use (10 runs of 2 to 2.5 miles each), I have no regrets with the purchase whatsoever.

I haven't had any of the problems reported by any of the one-star reviewers. It syncs to the satellite in a reasonable* amount of time, seems to track my pace very well, tracks distance well, and the heart rate monitor seems WAY more accurate than the dedicated exercise machines at my local gym.

*by reasonable, it does take a minute or two to sync to the satellites each time. That's the only thing I could possibly think of improving, but it's not a big deal. Being the super-impatient person I am, I often turn on the watch, set it on my front porch, go back in and change into my running outfit, and by the time I come back out it's ready to go.

I haven't seen the pacing issues others have reported. I'm a beginning runner... but if I keep a solid pace... it reports about 10mins/mile... if I push a little harder... about 9mins/mile... if I let up... about 11mins/mile. It seems very consistent over my entire 2-2.5 mile run.

I have a 2.1 mile run where I've done the same exact route about 6 times... and when I compare the maps of each run... they overlap almost exactly.

I have thyroid and heart issues, and this watch gives me the confidence to know I'm not exceeding my max hr for too long (I can easily get into the 180's) and gives me the feedback and stats to keep me motivated.

Last but not least, I've bought dozens and dozens of items from Amazon over the years, and this is the first review I've taken the time to write - hope that gives you an indication of how happy I am with this product. ;-)
