That bit of equipment only works with Plane Plotter as far as i know, which will not give you anything you cant get for free on Flight radar 24/7 as i see a feeder in the Christchurch area . the system your looking at will only show ADSB aircraft that can be tracked , none traceable aircraft will not show up, .

Thanks Steve you have saved me $345 but may now cost me the $800 hahaha after all it is Christmas and all the none regret comments may have twisted my arm !
