GPS Tracking Devices

Being the big brother to the Garmin Forerunner 205 GPS watch it might be helpful to read our product review for that model. The two models share basic features, size and functionality with the Garmin Forerunner 305 including the heart rate monitor. An optional feature available with the 305 is a cycling cadence counter but we did not test that option. It should be mentioned that the heart monitor and cycling sensors will work indoors since they do not rely on the GPS signal to function. So if you also work out using stationary equiptment these features will be useful.

For those interested in peak training we think a GPS  watch must have the heart rate monitor. It works well and when training on varying terrain there is simply no way to gauge heart rate without a monitor. In use the heart rate monitor readings do not “bounce around” to much but instead they remain reasonably steady. This allows a quick glance at the screen less often and with more confidence in the accuracy of the reading at any given time.

Since GPS accuracy is important to most users we paid attention to that while running and also double checked the readings with several other GPS devices. To satisfy our curiosity we brought the Forerunner 305 watch along for a highway road trip and verified its accuracy using the highway mile markers. In all tests we found the accuracy to be excellent and cannot imagine the need for greater accuracy, given the presence of a strong signal.
