Reviews: Garmin GPS Heart Rate Monitor

A normal adult heart rate at rest ranges from 60 to 100 beats per minute and for a well-trained athlete it is around 40 beats per minute. A lower heart rate at rest for an adult generally means a better cardiovascular fitness. If you want to check your pulse simply place two fingers on the thumb side of your upturned wrist or under your jaw along your windpipe. However this process can be a hassle when you’re training. So the best alternative would be the use of a heart rate monitor.

My two favorites are the Garmin 305 & Garmin Forerunner 405cx GPS monitors. Read on so you can determine which Garmin GPS Heart Rate Monitor suits you best.

Garmin Forerunner 305


We’ll start with the Garmin 305. This Garmin GPS Heart Rate Monitor is developed from the 301 version. Unlike the 301 version the Garmin 305 has a waterproof design. It’s still bigger than a sports watch but comfortable to wear. It has a high display resolution making the readings clear and precise. I like the simple but effective button layouts on the Garmin 305. The right side consists of the menu selection and enters buttons and the left side has the power and backlight button and also a mode button. The buttons have such good pressure response that I hardly have to press twice on a button or apply great pressure to get what I want.

What you need to know about the Garmin 305

On the underside of this Garmin heart rate monitor is a single mini-USB port. I use a USB cable or AC adapter to transfer data to my PC and I also charge the Garmin 305 in the same way. How does it help me? This Garmin GPS Heart Rate Monitor helps me track heart-rate, average heart-rate, heart rate zones, calories burned, elevation distance, heading, and grade. If I were to include additional features I wouldn’t have the space and time to tell you about the second Garmin GPS Heart Rate Monitor which is the Garmin Forerunner 405cx.

Garmin Forerunner 405

The Garmin Forerunner 405 is the epitome of any GPS training technology. In this age of instant data transfer, the Garmin 405 tracks your heart rate, distance and pace, and wirelessly sends the data to your PC for later analysis. With this wireless technology, this Garmin GPS Heart Rate Monitor allows you to share your locations, workouts and courses with other 405cx users. All you have to do is select ‘transfer’ to send your data to a nearby device.

Final Thoughts and Outlook

A very generous company in our town gave each member of my cross country running team a Garmin Forerunner 405cx. It has made the kids even more enthusiastic about training and monitoring their progress. It has also bred some very healthy competition amongst them. This Garmin GPS Heart Rate Monitor tracks your heart beats per minute and uses this data to calculate the calories you burn. It is good for athletes who want to train in a certain heart rate zone and monitor their progress. Thankfully it is not all that bulky and can be purchased with a smaller strap for smaller wrists. All in all, this Forerunner 405cx is a great exercise companion.
