A high precision numerical analysis of the static, spherically symmetric SU(2) magnetic monopole equations is carried out. Using multishooting and multidomain spectral methods, the mass of the monopole is obtained rather precisely as a function of $\beta =M_H/M_W$ for a large $\beta$-interval ($M_H$ and $M_W$ denote the mass of the Higgs and gauge field, respectively). The numerical results necessitated the reexamination and subsequent correction of a previous asymptotic analysis of the monopole mass in the literature for $\beta \ll 1$.
