The reason I am asking is that I want to know if the VStank emitters are compatible with the IR targets made by Nick at www.rctankhobby.com.

He told me that they will pick up anything between the 36-40kHz range. If I can find out what frequency they are, he can get a detector that will work for it.

I suppose the best way is to just buy one and try it. If it doesn't work, swap out the detector.

It would be great to have a few of these detectors build into some battlefield objectives.
