GemRed 12" Digital Goniometer 360 Degree Physical Therapy Protractor | for Joint Range of Motion ROM Measurement

First time using a digital gonio and I have no clue how to read it. I was taking measurement for a patient's knee flexion and the digital reading was way off. Looking at the display numbers on the ruler had a different read than what was shown on the digital display. Am I missing something, or am I calculating the difference between the two read? Any help would be appreciated.

Simple goniometers are just too hard to read in my busy clinic. I don't have time to fumble with reading glasses, notes, the patient, and the goniometer all at once. I like the "Hold" function in case I have a question to answer before I can jot down my findings, which happens basically always. I recommend this item.

The battery was NOT included as advertied.

I am a PTA and this has been very useful. My eyes are not what they used to be and this helps a lot!

As the title states, I could not place the battery in the container. The battery container does not open therefore I can't place the battery which makes the goniometer unusable. I was never able to use it.

De buena calidad y fácil de usar

Muy buena calidad , voy por mas !!

I can’t tell you if it works because I can’t get the battery compartment open . It refers to a “tool” to use while pressing the button and pulling it open on both sides. That is one more hand than I have ! Update: They sent a new one, still very difficult to open the battery compartment but I finely got it.

Great device and easy to use. Helps speed up assessments

Se requiere tiempo para acostumbrarse a trabajar con el pero buen producto

Leicht zu benutzen und präzise.

Parfait correspond bien à mes attentes

I very good and accurate, the buttons are small and hard to press to reset to zero but it's not impossible just fiddly. Other than that it's a great peice of kit and much faster than calculating from a non-digital piece.
