MultiDeco-X1 is a full decompression firmware program that uses genuine VPM-B and VPM-B/E, and Erik Baker's Gradient Factors (GF) for its decompression calculations. MultiDeco-X1 computes the ascent every few seconds, starting with regular NDL limits, and progressing into the decompression limits.

MultiDeco-X1 builds on the success of V-Planner Live, and brings more deco model choices and options to the diver. MultiDeco-X1 adds new ways to view the PO2 data and allows the diver to adjust the dive views.
