First let me say that I own a X-705. I'm not bashing the 705 or inferring that it isn't an adequate detector. My question has to do with what I consider a recent development regarding price. I've watched the value of used 705's drop significantly and I don't know why. I've read posts from others raving about them; I can attest through my own use of a 705 that they work well, but the used prices I've seen don't reflect it. In my experience used 705's were selling in the $500 range and now are closer to $400. That's a 20-25% drop. Do you think the used market price has dropped? Do you think used 705's are undervalued? Or do you think there is an over-saturation of x-terra's on the market and the price is reflective of supply and demand?
