Store Open – Polar & Suunto

We have focused on the online sale of just TWO brands, Polar and Suunto. We selected Polar & Suunto above all the other brands for several reasons. Polar were the original innovators of heart rate monitoring way back in 1976. They fully understand the needs of the elite athlete and comprehensively apply that knowledge to the average person’s requirements. Suunto are the undisputed world experts in outdoor adventure watches.

Polar have a wide range range of products accommodating the needs of everyone. From the customer looking to improve their lifestyle, to those wanting to advance in their chosen sport to the elite performer at the pinnacle of their sport.  Suunto’s range is for the dedicated outdoor sports professional whether a cyclist, runner, triathlete or adventure racer.

The BEST Heart Rate Monitor watches


The Garmin Forerunner 235 is a joy to use and has everything a runner will need from colour coded heart rate zones, personal best alerts, Bluetooth synchronisation to Garmin Go APP and, best of all, STRAPLESS heart rate via built-in HR sensor on the back of the watch. However, the value for money and comprehensive list of features make the Polar M400 a very highly recommended alternative.


Another hard category and one that is VERY competitive at the moment. We’d recommend the Edge 25 for it’s micro size, ease of use, connectivity to smartphone. It’s got everything 95% of cyclists will ever need. If you’d like my training feedback then there’s Polar M450 for it’s brilliant interface, built in fitness tests, training load indication (recovery time) and emergency front light.


This is another shared title. We’d be happy to tackle any triathlon with either the Polar V800 or the Garmin Forerunner 920XT. The Suunto Ambit3 Sport also has to get a highly recommended mention. They all offer single button transitions, smartphone alerts and notifications, customisable display options, swim-metrics, optional pedal power monitoring and much more.


The most popular category and with over 50 products to choose from it’s should be a hard one to call. It’s not – if you want the best activity tracking bracelet/watch with OFF the WRIST heart rate, smartphone APP support, training benefit feedback and more – Polar A360 all the way. Another that comes highly recommended is the brilliant Garmin Vivoactive HR

Listening to your body is one thing, understanding what it is telling you is an altogether different story. A Polar Heart Rate Monitor helps you to get under the skin of your training. Polar put it down to a combination of expertise in sports, physiology and electronics, coupled with the best understanding of customer needs.

It’s no surprise then that they have been leading the way in technological innovations in  heart rate monitors since 1977. The best Polar HRMs from the current range would have to be the Polar M400 and strapless HRM / activity tracker the Polar A360

Suunto has been at the forefront of design and innovation for sports watches, dive computers and instruments used by adventure seekers all over the globe. We’ve owned and tested dozens of their wrist computers and we’re pleased to share these Suunto sports watch reviews with you.

From the highest mountains to the deepest oceans, Suunto physically and mentally equips outdoor adventurers to conquer new territory. The best Suunto wrist computer from the current line up would be the Ambit3 Sport tested here

Garmin’s mission statement “to be the global leader in every market we serve, and our products will be sought after for their compelling design, superior quality, and best value”. We think they’ve exceeded that goal. We’ve been lucky enough to use most Edge & Forerunner products and want to share our these Garmin product reviews with you

The Edge and Forerunner have been the MUST HAVE fitness product since the Forerunner 101 in 2003. It’s difficult to call the best all round sports watch from Garmin, but the VivosmartHR and FR235 get our vote

Say TomTom to anyone you meet and they will probably think of in-car GPS navigation…. not anymore. We’ve reviewed the TomTom GPS heart rate monitors and we have been very impressed so far. We especially LOVE the strapless heart rate monitoring from the heart rate sensors on the back of these watches.

The best watch for the all rounder has to be the MultiSport Cardio with built-in GPS & HRM. If you want chest strap freedom the choice is growing with FitBit, Polar, TomTom, Mio, Epson and Garmin

TomTom GPS sports watches and heart rate monitors


When you’ve been involved with heart rate monitors as long as we have there is one thing that everyone has been asking for since pretty much the day we started…  STRAPLESS and CONTINUOUS heart rate monitoring. For decades you have had to chose between ON DEMAND heart rate, touching sensors to get a reading or CONTINUOUS with a CHEST STRAP

Thanks to Liz Dickinson and her team at MIO we now have CONTINUOUS heart rate monitoring directly off the wrist with optical sensors on the back of the watches. BRILLIANT ! We have completed several reviews of the Mio heart rate monitors and give them a strong 9/10. Our favourite is the Mio Fuse with off the wrist HR and activity tracker

Mio Strapless heart rate monitors


FitBit burst on to the scene a couple of years ago and have blazed a trail of innovation ever since. Their unique style and close contact with their customers has turned them in to a World Leading brand. Their products not only give invaluable fitness tracking feedback but they also look great. A choice for the customer who wants their fitness monitor to look discrete & cool.

We have reviewed many FitBit products and are pleased to share our views with you. This is a company who have their finger placed firmly on the technology pulse and provide some of the cleanest and most easy to use APPS on the market. Charge HR and Surge are our favourites with BUILT-IN heart rate sensors

Epson… printers? Yes, but they were also have an excellent range of fitness monitor watches with continuous heart rate sensing. Using a similar technology to TomTom, Epson have thrown away the chest strap and integrated new strapless heart rate monitoring in to their range of watches. Epson have been very brave joining this party with world leaders like Garmin and Polar and other newcomers such as TomTom.

We’ve tested several of these new products and are pleased to share our Epson GPS & HRM reviews with you here. Please take a look at these new products from before following the herd. The Epson SF810 is a great all rounder with optical HR sensor (no chest strap) and built-in GPS

Epson heart rate monitors and fitness trackers


Timex have been one of our favourite brands since we started selling their range back in 2004. Timex have been innovators in the field of GPS and Heart Rate Monitors for over a decade now. They were the first company to have a truly digital transmission from the heart rate strap to the watch – to cut out interference.

Timex have some of the sleekest GPS running watches on the market with their new Move X20. This is a new range, so please visit our Timex GPS heart rate monitor reviews if you’ve not looked at Ironman watches for a while. Timex have been a bit quiet lately but we hope to see some innovative new products soon.

A Brief History…

It all started in 1996. As a sports science student I wanted to promote the use of Heart Rate Monitors in exercise. The business went online in 1999. In 14 years we sold HRM's to over 300,000 customers.

After a short retail back we're now back with the new online store selling ONLY Polar. We still offer impartial advice & test other heart rate monitor brands. Our aim however, is to introduce you to Polar's products as an alternative to Garmin, Fitbit, Suunto or TomTom.
