  Recently N. Arkani-Hamed and S. Dimopoulos proposed a supersymmetric model
\cite{Arkani-Hamed:2004fb}, dubbed "Split Supersymmetry" in Ref.
\cite{Giudice:2004tc}, which can remove most of the unpleasant shortcomings of
TeV Supersymmetry. In this model all scalars except one finely tuned Higgs
boson are ultra heavy while the neutralino and chargino might remain light in
order to achieve gauge coupling unification and accord with the dark matter
density. In this paper, we investigated the impact of this new model on
chargino pair production at next generation linear colliders. Our numerical
results show that this process can be used to probe sneutrino mass up to 10
TeV. Therefore, precise measurements of chargino pair production at the linear
colliders could distinguish Split Supersymmetry from TeV Supersymmetry.
