Default Binoculars with compass

Hi Guys,

Sorry if my post is not in the right group, I'm not a sailor or a boatsman.

I purchased a pair of binoculars STEINER COMMANDER XP with (magnetcic)
compass via internet.
When I received de binoculars I remarked a big air bubble in the
stabilising fluid and a deviation (with respect to a (magnetic) handcompass
with optical prism) when shooting bearings.
I sent the binoculars back to Steiner for repair and after three weeks my
toy came back. The air bubble had disapeared but not the deviation.

Due north with a reference compass the STEINER indicates 002.5°
Due east with a reference compass the STEINER indicates 095.5°

A quick series of measurements (beginning north and with increments of 30°)
reveal a positive deviation with a maximum of +6.5° (from 0° to 180°) and
maximum deviation of -5° (from 180° to 360°). Drawing a graph with de
deviation values as a function of the bearing angle gives a sort of
sinusoïdal curve.

I contacted STEINER but got no reply yet.

Are there STEINER users among you with similar experiences?

Thank you for reading my post.
