Dollar for dollar, feature for feature, this caller is one of the best values available to predator hunters. From Johnny Stewart, the #1 brand in authentic wildlife sounds, comes a three-mode calling unit. It features STANDARD, which plays precisely as recorded, SOUND SHUFFLE, which randomly shuffles sound segments of the original loop (critters won't get conditioned or educated to repeated sounds); and CUSTOM SEQUENCE, which plays sounds in a sequence programmed by the user. Comes with 75 Johnny Stewart authentic sounds and has 12 sound presets on the remote and 12 sound presets on the base unit. It can play two sounds simultaneously. The Gallows features integrated GPS and the remote operates up to 300 yards. Operates in all audio formats, including 24 bit and 32 bit and has 4 GB of internal storage. The keypad and base have a LCD display with real-time clock, stand timer and power save. The volume selection of 0-50 can be adjusted while in mute. The Omni-directional speaker sets the standard in sound sensitivity and frequency range from low to highs. It uses 8 AA or 8 C cell batteries.
