I’ve had my Garmin Forerunner 305 for 2 weeks now and have been quite pleased with it. A few people have asked me for a review of the unit, so I’ll do the best I can.When I first opened the box, I put it on the docking station plugged it into my DC inverter in my car so that it could charge on the way home from REI as I wanted to use it that day and it was supposed to charge for a few hours. After I got home, I plugged it in and it was ready to go in no time. I turned it on, took it outside and it acquired a signal pretty quickly. I browsed the instructions while waiting for it to charge, but didn’t thoroughly go through them.There was no configuration required and I started my first run by strapping on the heart rate monitor (I read a tip that said to put water on the monitor before putting it on), putting the monitor on my watch and I was off. There really was no configuration needed to get it going. It seemed to keep a signal and gives me the data I need to train (current pace and heart rate are about it).I’ve read some complaints about the unit from others in that it doesn’t keep a signal, the heart rate monitor doesn’t work, etc. My unit has performed flawlessly and keeps the signal all the time; I don’t run in wooded areas and there is pretty much a clear view of the sky. Also, the heart rate monitor works fine; another complaint I’ve read has to do with the heart rate monitor not registering when the GPS unit is placed on bicycle handlebars or on a crossbar on a boat. Since I run with it and it was designed for running, it works well. My only problem with the monitor was that I didn’t wet it down one day so it didn’t start registering until I had worked up a good sweat.If I wasn’t a techno geek, I’d stop here as the Forerunner tells me my pace, distance, and heart rate which has been helping me train. One of the reasons I went with the Garmin device is that Garmin announced Macintosh support for their products. The Forerunner comes with Training Center software which currently only works on Windows; I haven’t bothered to install it as Garmin’s subsidiary, MotionBased, put out a beta version of a Mac plugin that uploads data from the Forerunner to the MotionBased website. I love data analysis and this site has more data than I could ever need.The Forerunner has so many options, I don’t even know where to start. I configured my main screen to show my pace, time, and distance. I then configured a secondary screen to show my heart rate and average pace. It took me a few days to figure out that I could reconfigure the screens as I didn’t bother reading the instructions. The device does limited navigation (to get me back to where I started), handles multiple types of activities, etc. I currently have no use for lots of these options, but I’m sure I’ll discover them when I need them or I get bored.I’m quite impressed with the device; it appears to give me accurate information about distance and time. I’m not sure what else I could ask for in a device. I’m definitely giving this device a thumbs up; it makes me excited to get out and run.
Pros
- Easy to use
- Large readable display
- Reasonably accurate distance tracking (I did compare a run with Google Earth and found it to be close)
- Lots of options
- Not too bulky for what it does (looks better than the Twinkie shaped Forerunner 301)
- Partial Macintosh support for MotionBased; more is coming
- Can charge over USB
Cons
- Current desktop software is Windows only Update: Mac software is available. Read my first impressions of it.
- Training partner is annoying to me, but maybe when I get better it won’t bother me as much
Some pictures of the unit are at the end of this entry. If anyone has specific questions, please post a comment and I’ll try to respond.





Hi Rasmus,
No, the elevation function is still not working. It seems to aggregate the +/- 30 ft GPS fix error rather than intelligently smoothing/correcting like it does with distance. Today's hike had me 170 ft below sea level. Even with no bad data points and smoothing enabled the elevation numbers are at least 2X what I'd expect. The elevation profile for an out-and-back hike is also significantly off, so the 305 isn't even building a consistent error.
There is a program called SPORTTRACKS that says it can read garmin 305 data and has a plugin that "...corrects the elevation of GPS tracks using SRTM elevation data, which is automatically downloaded from the official SRTM download server...." Use google to find it (disclaimer: I don't use sporttracks software, and don't care that elevation is obviously wrong).
Aside: for hiking the calorie function seems about right -- just slightly more than 100 cals / mile.
After almost 4 years of use, my Forerunner 305's battery died. It has served me well, but stay tuned for my updates on its replacement.
Scott,
My battery died, on my Forerunner 305, after almost 4 years also. Let me know what you do as far as replacement. I'll keep looking and pass the word once I find out.
I bought a Forerunner 405 and am pretty happy with it. When I get a chance, I'm going to write a review.
Good to know your 305 lasted almost 4 years
I get mine in the mail tomorrow! Yay. After lots of research and bloggy advice I decided to go with the 305 vs. a newer version, less problems was the verdict. Thanks for your review, and enjot your new Garmin... what was his name?
I don't name my devices as I'd never be able to keep them straight! I went with the 405 for a number of reasons that I'll eventually write a review about. In short, the wireless connection for downloading is great, I like how it charges better (a clip that doesn't pop off), it has a battery charging gauge, I wore it while walking around San Francisco and didn't look too much like a dork, and I like the side buttons for starting/stopping and resetting it. However, so far, the bezel is bit of a pain. I'll try to write my review soon.
