We use the excellent BFG tcas in our MD902 on police ops. the display may be a little small but it covers all the bases with information out to 5 - 10 - 20 miles. you can set it to look up 9000ft and down 2700ft at the same time - good for low level when your head is out of the window. <img src="cool.gif" border="0"> <img src="cool.gif" border="0"> <img src="cool.gif" border="0">
