mainly because the vibraprobe will cause the C$ to have a fit if the coil is within 3 feet or so of the hole, same thing thing with the GTi so that's why I bought an inline probe for the GTi. Now as far as the small coil goes, don't need one, won't use one, I don't hunt areas that I would use one enought to warrant spending the cash on one.
Now, I have spoken to Ralph many times about the C$ probe, he's been as honest with me as he can be I expect without letting any cats out of the bag. Now, when I saw a probe release for the Ace detectors, that's when I came to the realization that there probably won't be a C$ probe. If its economics then I can't see the Ace probes generating a lot of money, if I'm wrong, which I hope I am, but I myself wouldn't consider buying a probe that cost as much or almost as much as the detector I'm putting it.
Will no C$ probe make me want to sell my Coinstrike, NO, I had thought about trading it, but I did that once and bought another 6 months later because I missed it.
I figure it's not Ralph's fault that theres no inline probe for C$, I just figure it's because there might be a problem creating a probe that will work on the C$.
