Not sure if I'm missing something but on eBay the CZ-3D has been seenng for around $400. A Racer, SE Pro and a CoRe for a CZ-3D? Someone is out to lunch.
So far I would agree with tnsharpshooter. The Racer, in my opinion, has raised the bar for mid-lever detectors. It is knocking at the door of the top of the line machines when it comes to performance. Features wise is where the top of the lines still stand above the others. For those who don't care about more adjustable discrimination, More tones and VDI options, custom programming ETC. then the Racer is going to save you money and still give great performance.
Personally I don't think it will pose a great threat to detectors like the E-Trac/CTX/V3i/Deus, except in performance, but I do believe Makro will have Fisher scrambling to either produce a new machine or lower their price. I can see some reasons one would send the extra money for the E-Trac/CTX/V3i/Deus but I can't see why anyone would send the money for a F75 SE2 over the Racer.
The jury is still out on the Racers gold ability. I hunted a tot lot yesterday and it was OK. Nothing special nothing bad. The gold I have tested on the racer again was OK not a spectacular gold machine but not bad. In my opinion the AT Pro and Deus still respond better to small odd shaped gold but again the jury is out yet.
I will be doing a great deal of testing of the Racer today and get some more videos.
