Technical Information

Your progress indicators
Step count, distance covered.
The ONwalk 100 measures your walking activity using a 3D accelerometer. Thanks to this technology, the ONwalk 100 gives you accurate readings wherever you position it: in your pocket, in your bag or on your belt.
The ONwalk 100 automatically starts counting your steps and distance when you start moving. Hold down the central button for a few seconds to reset the counter.
Automatic stride length
Your walking distance is calculated based on your step count and your stride length. For ease of use, the ONwalk 100 automatically estimates your stride length based on your height. If you wish, you can manually enter your stride length to improve accuracy.
Automatic standby
The ONwalk 100 switches to stand-by mode after 30 seconds of inactivity in order to maximize battery life.
CR2032 battery included.

Was very disappointed with this item and had to take back for a refund. Having purchased two of these previously I wanted to buy one for my mum to use. After setting it up for her, i was disappointed to find that reset the steps to 0 as instructed in the manual and as i normally did with the previous two i own and used. It seems the technology in it has changed.
Response of the brand
Hi Ivan,

The process to reset the steps is to hold the central button for 1.5 seconds.  I'm sorry that your pedometer was not doing this but it could be a defect with that specific pedometer rather than the technology changing.

There is an FAQ available on the Geonaute website for this product should you need it: 

You have the peace of mind to know that all Geonaute products are covered by a 2-year guarantee against defect and you can return as you have done or exchange.

Kind regards,

Great, Mum Loves it!
Used for More than 2 years
Even survived a trip in our washing machine. Lasted perfectly for nearly 2years, until it was stepped on accidentally when it got dropped. Will buy another.
Attaches greatly on the hip on clothing.
There is no way to lock the buttons on the front of this pedometer, so if the buttons are brushed against during your day, the whole thing resets and you lose how many steps you have taken as it starts from zero again.
Response of the brand
Hi Dave,

Thank you for your feedback regarding the Onwalk 100 pedometer.  Following feedback given in reviews citing a similar problem of the pedometer resetting there have been changes made to the design that will arrive in store shortly.

As it is not currently available you are more than welcome to return the pedometer to the store on your next visit for a full refund.  I'm very sorry that you've had this problem but I thank you again for your feedback as it allows us to improve our products.

Kind regards,

David Daker Commercial Director DECATHLON
