The Destination Analyzer is a block added by RFTools.
The Destination Analyzer is a passive device placed adjacent to a Dialing Device that allows the player to check the status of a teleport destination prior to transit. The device has no GUI and is operated by clicking the check button in the Dialing Device GUI. It may also be placed adjacent to a Matter Transmitter. In this application, the teleportation beam will be tinted red if the destination is unsafe.
