The Garmin Forerunner 305 is very similar to the Forerunner 205, in fact, it is identical in size, shape, performance and functionality with only a small couple of exceptions. The main difference is the 305 includes a heart rate monitor and can include a counter cadence device. These options make the Garmin Forerunner 305 a good choice for a lot of runners, even for the most serious athletes. Notable features of the Garmin Forerunner 305 include;

Features of the Garmin Forerunner 305

If you are interested in getting the most out of your training efforts, I believe that the heart rate monitor with the Forerunner 305 is a must. It works well and there is no other substitute for precision measurements of your heart rate which lets you adjust the intensity of the work to maintain the desired cardio objectives.

Use a Heart Rate Monitor on Your Forerunner

When training on varied terrain, the effect on heart rate is very pronounced and would probably surprise anyone who has not used a heart rate monitor before. When using the Garmin Forerunner 305 I found the data readings to be relatively stable enough I had confidence that they were accurate. If you don’t want heart rate monitor with your sports watch then check out the Garmin Forerunner 10 which is much cheaper than the 305 and 205 click here for a Garmin FR10 review.

Data Read Outs Help with Fitness Levels

My view is that the data read-outs on the Forerunner give a good indication on your fitness progress. The Garmin Forerunner 305 is a step up from the Forerunner 205, with the main differences being that the 305 includes heart rate monitor, a feature missing from the Forerunner 205. Another option available with the Forerunner 305 is meter cadence, but I have not tested this option fully. It is worth mentioning that the heart rate monitor and cycling sensors work indoors because they do not rely on the GPS signal to work.

Strong GPS Signals Work Even in Dense Foliage

In my tests I checked the readings with several other GPS units and also checked with a measured mile. Moderate forest cover does not adversely affect the performance of the Forerunner device which is important because it may be frequently encountered especially with trail runners. The overall accuracy is excellent, given the presence of a strong signal, and should be sufficient for most people’s needs.

Garmin Forerunner 305 is Easy to Use

One area in which considerable progress has been made is the ease of use. The unit itself is not bulky to wear while training, in fact, it’s just like wearing an ordinary watch, just a little bigger. Overall, the design and functionality of the Garmin Forerunner 305 is excellent. The buttons are intuitive rather so you should not find it too hard to get up to speed. The average life span of the battery is about 8 to 10 hours. I would choose the Garmin Forerunner 305 over the 205 because the cost difference is only about $100, and the functionality is much better. Garmin has made this generation of GPS tracking watches better than ever, you should not be disappointed if you need a GPS-enabled running watch this year.
