This deluxe Caller uses the same Wireless Remote and Yellow labelled sound cards as the earler Standard model Caller for easier upgrade. This deluxe model has 2 sound card slots.
A key benefit with the wireless remote when hunting/filming or photographing animals, they will always come direct to the source of the sound. By placing the main hand unit at a distance, this will enable you a better look at the approaching animals. This is also a great SAFETY feature.
