Investigated the applicability of the principles of reciprocity (PR) in hydroacoustic waveguide for vector-scalar fields (VSF) of multipole sources (MS). It is shown that MS with this principle are divided into two groups: in the first group the fields of sound pressures (SP), horizontal projection of vectors vibrational velocity (HP VVV) satisfy PR, and the vertical projection (VP VVV) of this vectors do not satisfy. In the second group SP and HP VVV principle of reciprocity does not satisfy, and their VP VVV satisfy. Gradients of phase (GP) and the arrival angle in the vertical plane substantially not satisfy PR.
