The SmallHD FOCUS Bolt 500 TX-RX Kit combines the two FOCUS Bolt 500 monitors for a full wireless monitoring experience. Connect the FOCUS Bolt 500 TX to your camera and give your director or focus puller the FOCUS Bolt 500 RX and you can view HD video without cables (other than the HDMI connection to the video source). The small sizes of the TX and RX monitors make them easily camera-mountable and handholdable, respectively. With the TX monitor you get the FOCUS tilt arm, and with the RX monitor, rubber handles and a neck strap. For more information on both of these monitors, check the features below.
