    This isn't a laser question, but I want to calibrate my eye level but I don't know how. Can someone talk me through the process? Thanks in advance.

    its pretty simple. You have to find two know level marks say 25 yards apart, one can just be a grade stake the other is best if its a solid surface that you can work off. Find the adjustment screws in the eye level and adjust the bubble till it says that what you already know to be level is level to it. Next with the laser level or transit still set up, check another target in a different directiopn and see if its still on, just to be sure.

    Here ya go !

    ADJUSTMENT
    On a level surface set up a stable stand or tripod at eye level 15’ to 20’ from a vertical surface such as a wall. Place hand level on stand and use a tape to measure from floor to middle stadia line in field of view.
    Mark a target at the same height on wall. Tilt hand level slightly up or down until the middle stadia line is level with target. If the bubble is not centered within the upper and lower stadia lines,
    unscrew the objective cap assembly and use a flathead screwdriver to turn the adjusting screw.
    Turn adjusting screw clockwise to lower bubble, counterclockwise to raise it. Replace objective cap and check adjustment. Repeat process until the bubble is centered when middle stadia line is level with target on wall.
    Note: This is a basic adjustment. For a more accurate adjustment hand levels may be sent to the
    factory.

    If you need more info , here is a link to the whole procedure
