We study the detection of the complete spectrum of Higgs bosons of the minimal supersymmetric standard model, through their decays into chargino ({chi}-tilde{sub i}{sup {+-}}) and neutralinos ({chi}-tilde{sub i}{sup o}), for several parametric scenarios. In the minimal supersymmetric model there are two charginos and four neutralinos, and the Higgs boson spectrum contains three neutral scalars, two CP-even (h{sup 0} and H{sup 0} with m{sub H{sup 0}}>m{sub h{sup 0}}) and one CP-odd (A{sup 0}, with m{sub A{sup 0}} as a free parameter); as well as a charged pair (H{sup {+-}}). An interesting signal comes from the decays of the Higgs bosons into invisible SUSY modes (h{sup 0}, H{sup 0},A{sup 0}{yields}{chi}-tilde{sub 1}{sup o}{chi}-tilde{sub 1}{sup o}), which could be detected at present and future high energy machines.
