By the way, being able to discriminate the target with the pinpointer is something I never used anyway. I don't know about most people but once I commit myself to bending down and digging a target it's coming out of the ground regardless of if it turns out to be junk or not. That's the hole point to a pinpointer...being able to find the target without having to get back up and re-pinpoint it with the detector.
I'm also not going to leave another iron "trash" signal in the hole even if I already have pulled a coin out of it. I don't like those odds, as there could easily be more coins that were dropped with the first one I recovered and are being masked by iron or other junk. Not to mention the old rule about less trash being there to mask coins the next time you hunt the spot.
That's also why I like to dig any other signals above iron within 3 or 4 feet of a good recovery. An example of this would be a friend who dug two large cents out of one spot. He invited me over to sweep the rest of the area around where they came from. About a foot or two away I was getting a jumpy signal acting much like a 22 casing. I'll tend to ignore those in certain areas because they are all over the place. Anyway, it ended up being an 1858 silver 3 cent piece in mint condition.
Ask yourself this...If you dig the hole on an "iffy" coin signal and your probe is telling you it's trash, are you willing to cover it back up and walk away? I'd rather dig out the trash and hope the bad signal I was getting was due to a nearby coin. Once I've taken the time to bend down and dig out a target I'm not getting up without it, trash or not.
Mainly, though, it's the weight, added wires, and what I thought was a major hassle to use the Sunray...Snap it off, throw a switch or two, snap it back on. Try to remember to throw the switch back or hunt another five minutes before I realize why my detector isn't picking anything up with the coil. Just the fact that I have to use two hands to snap/unsnap the Sunray back to the shaft is more trouble than it's worth to me. I generaly try to keep my right hand somewhat clean and use my left for digging and sorting through the dirt. That way I'm not getting more dirt than I have to on my detector. Since the Garrett Probe is for the most part waterproof and can be rinsed under water I don't have to worry about how dirty it gets.
It comes with a nice holster that makes removing/replacing it very quick and easy. In many cases by the time I've snapped off the Sunray probe and set it up properly I can already have the target located with the Pro Pointer. Left hand is all I need to throw it back in the holster and go about covering the plug back up.
I'm sure SunRay lovers can find just as many reasons why they prefer it over the Garrett. You have to decide which of the pros and cons of these two units best suits your hunting methods and pick one based on that.
