Need help with which one to use

[Garten Haeska]

Could anybody provide any incite on whether I should use an accelerometer or a gyro on my shooter to get the angle that it is currently at.

I have never used either of them that is why I am a little lost.

Any benefits of either one?

Just a little clarification on the photo, it would be mounted on the c channel that is right below our shooters wheel. To sure where on that the c channel or which side but we want to measure the angle of that side c channel.
