Designed by expert Terry Denmon, who has called predators for yearslarge and small, dangerous and otherwise on 4 continentsthis caller brings the quality he insisted on that you can't find in imitators' predator call machines. This MOJO electronic call includes 80 proven sounds, all from a high-quality cone speaker for unrivaled sound with a dual sound storage and retrieval system. All sounds come on a preloaded SD card as well as in the onboard memory. The caller automatically senses an inserted SD card and defaults to those calls, or plays onboard sounds in the absence of a card.
