  We explore squeezed coherent states of a 3-dimensional generalized isotonic
oscillator whose radial part is the newly introduced generalized isotonic
oscillator whose bound state solutions have been shown to admit the recently
discovered $X_1$-Laguerre polynomials. We construct a complete set of squeezed
coherent states of this oscillator by exploring the squeezed coherent states of
the radial part and combining the latter with the squeezed coherent states of
the angular part. We also prove that the three mode squeezed coherent states
resolve the identity operator. We evaluate Mandel's $Q$-parameter of the
obtained states and demonstrate that these states exhibit sub-Possionian and
super-Possionian photon statistics. Further, we illustrate the squeezing
properties of these states, both in the radial and angular parts, by choosing
appropriate observables in the respective parts. We also evaluate Wigner
function of these three mode squeezed coherent states and demonstrate squeezing
property explicitly.
