What would you recommend for a beginner searcher that don't want to / can't spend much money on a detector?

Won't ever be "serious" about it but know of an area that had ALOT of action during the civil war and myself and the landowner both think it would be very interesting to just see what we could find by walking the area with a detector.

I would say top end of budget would be $300 and that is very top of the top end. \:\)
