  We report a detailed magnetotransport study on single crystals of PrBi. The
presence of $f$-electrons in this material raises the prospect of realizing a
strongly correlated version of topological semimetals. PrBi shows a magnetic
field induced metal insulator transition below $T \sim 20$ K and a very large
magnetoresistance ($\approx 4.4 \times 10^4~$) at low temperatures ($T= 2$ K).
We have also probed the Fermi surface topology by de Haas van Alphen (dHvA) and
Shubnikov de Haas (SdH) quantum oscillation measurements complimented with
density functional theory (DFT) calculations of the band structure and the
Fermi surface. Angle dependence of the SdH oscillations have been carried out
to probe the possible signature of surface Dirac fermions. We find three
frequencies corresponding to one electron ($\alpha$) and two hole ($\beta$ and
$\gamma$) pockets in experiments, consistent with DFT calculations. The angular
dependence of these frequencies is not consistent with a two dimensional Fermi
surface suggesting that the transport is dominated by bulk bands. Although the
transport properties of this material originate from the bulk bands, the high
mobility and small effective mass are comparable to other compounds in this
series proposed as topologically nontrivial.
