Inaccurate HR readings
on April 30, 2026
Posted by: SVassil
HR rate sensor is inaccurate. Shows 90 when strap based monitor shows 150hr on my bike rides. I also had a chance to compare it to two different straps.
Tightening the watch wrist band makes no difference.
It’s essentially a piece of junk I’m returning

Awesome for serious adventure athletes.

The watch is literally every that I wanted in a fitness tracker with some bells and whistles for the profession. The Ruck app should honestly be spread across more platforms and I appreciate the light that I use daily. This watch is my new favorite in the line up. Ultras are too easy with the tracker and display in the watch face.

There is approximately 110 pages of poorly written instructions; buyer beware.

Instinctually better!

This watch is an upgrade from my original Instinct and has some new features including a torch light. That could come in handy during a hike or bike at dusk or in the early morning. Everything else is pretty much the same, but it does record and upload faster to the app.
