Frequently Asked Questions (FAQs)

Does LED style HR pulse monitoring work using SHIFT?2018-07-31T02:33:59-07:00

You can use SHIFT with LED style heart rate monitors. This includes the Apple Watch and Garmin watches that use LED HR monitoring. We have tested the HR functionality thoroughly.  A local shop has told us that they think SHIFT improves the reliability of LED HR monitoring because they notice that with SHIFT there is less pooling of sweat under the watch.

Below is an image from a customer who also had a question about the HR measurement.


This 3 sec video shows two LED style HR monitors in use simultaneously, the Apple Watch and the Garmin 235. We have also tested and validated accuracy of HR monitoring vs. traditional chest-strap HR monitors.

Why ask about male, female and height?2018-11-22T10:53:36-08:00

We ask about gender and height because we have found this to be a very accurate proxy for hand size. This allows us to send the band to you pre set-up with best adjustment. The wrist-band is adjustable and the thumbstrap comes in a few sizes. We will pre-set this for you based on height and gender. We also add in an alternative size thumbstrap so you can try a different size if you wish.

We’re not trying to be creepy, James and I just want to make sure you get the best experience!

What materials are used?2018-07-31T02:36:09-07:00

Viton™ and die-cast zinc. No nickel is used, so no need to worry about nickel allergy.

We have recently upgraded the original SHIFT to a 2.o version. We now use the exact same, extremely tough (and expensive) VITON material used in the Apple Watch Sport band, and have not raised the price to you ; )

Wear gloves with the SHIFT band?2018-07-31T02:50:45-07:00

We have worn the band with many running, cycling, and sailing gloves. Our advice is to wear it under the glove, adjusting the glove, as shown in this image below.

If you’re not using an LED HR monitor, you can also wear it on top of your glove, as shown here. We’re very focused on making it flexible.
