An apparatus is disclosed for use within a borehole for seismic surveying that has a vertical array of seismic receivers connected to a cable, a top inflatable bladder connected to the cable above the top seismic receiver, and a bottom inflatable bladder connected to the cable below the bottom seismic receiver. The top bladder acoustically isolates all seismic receivers from the borehole environment above the top bladder. The bottom bladder acoustically isolates all seismic receivers from the borehole environment below the bottom bladder. Additional inflatable bladders are placed between each separate seismic receiver in the array.
