We present a review of the possibilities to conduct experiments of high efficiency in the nuclear and high energy physics with spin-polarized beams in a collider complex, configuration of which includes Siberian snakes or figure-8 collider ring. Special attention is given to the recently elicited advantageous possibility to conduct high precision experiments in a regime of the <i>spin transparency</i> (ST) when the design global spin tune is close to zero. In this regime, the polarization control is realized by use of <i>spin navigators</i> (SN), which are compact special insertions of magnets dedicated to a high flexibility spin manipulation including frequent spin flips.
