The TKI black box mounting plate may be added to your graph mount order. It was designed to mount the Garmin Panoptix and Lowrance active target black boxes behind the head unit. The plate makes installs easy and the black box accessible for easy removal or troubleshooting of the unit. The plate is made of stainless steel and has both mounting options for Garmin Panoptix and Lowrance active target black boxes. If you add this mounting plate to your order, it will include mounting hardware. Depending on the graph, this plate sets the black box approximately 2 inches behind the graph so that cables can be connected to the head unit. The plate will be mounted under the gimbal mount of the head unit, once the plate and gimbal are mounted, the black box can be installed. We find a short network cable to be the best option, it leaves less cable mess behind the unit and makes wiring nice and neat. The TKI black box mounting plate weighs 2.5 lbs and is 10 x 6.5 x 4.
