The two products are compatible; in fact they are made to be used together.
First, build a Camera Calibration with SpyderCHECKR / SpyderCHECKR 24 to define your camera’s color response. Then, when you do a shoot, use the SpyderCUBE to capture information about the scene lighting. Make your usual SpyderCube adjustments for gray balance, exposure, brightness, and blacks, and then apply your Camera Calibration too.
You can now save this combined Lighting and Color Calibration preset to apply to all the images from that shoot.
If you use the SpyderCHECKR (not SpyderCHECKR 24) you will also have a possibility to mount the SpyderCUBE on the SpyderCHECKR.
