Can I perform other biofeedback scans in scalar field? Why can I do biofeedback scan using Scalar Digitizer?

No, you cannot perform other biofeedback scans whilst in scalar field, since they use different detecting way and the field will affect the scan results. For example, Spooky2 Pulse detects your heart beats, which would be affected by the scalar field. However, Spooky2 Scalar Digitizer measures tiny changes to the scalar field during scalar frequency scans, while GeneratorX records how the electrical signal behaves, so only Scalar Digitizer can do biofeedback scan in Scalar field.
