I participate in a lot of transmitter hunts.

If he wants to hunt with an omni, all he needs really is a step

I was thinking of using GPS too, but here is how I would do it. I have a
4 antenna doppler array that gives real time headings. The array is
mounted on my vehicle. The doppler unit sends four bit BCD to a 16 LED
heading indicator.


I believe there is a kit you can build:
