A little background info: I once owned an S7 X50, well after many years of service it got sick. I really liked that detector. Anyhow, I went detectorless for a while. I opted recently to purchase a Bel V10. I think it is a good unit. I was curious about the newer black X50 but didn't have the extra $110 to spend. I contacted RR about the V10 to see what his opinion was and his exact words were "I think it sucks! It is a cheap imitation of the Pro300. It's performance is sub-par......" So, I get a bonus from work and went and bought the newer black X50. It is the lighter weight one, who knows if that matters. But I can assure you this. That X50 is not any better than the V10. In fact it annoys me in several ways. First I must say, range is identical. But the X50 laser falses often. OK well fine. 2nd the X50 has issues with the signal strength meter matching the tone (I do admit there is a difference in Bel vs Escorts tone rate, but I am cognizant of it). It is when I use Expert mode that this happens. It's as if the unit is plain confused about what to say and what to display (for example, it can be showing two dots and be in what i call a flat-line tone and vise versa, keeping in mind only K-band is shown. Ie no other bands at a different rate confusing me...). 3rd, Automute doesn't work correctly. Many times it will start a fresh alert out in the muted volume level, meaning it hasn't just picked up said alert closely following a previous alert. This not a case of buyers remorse, it is merely my experience with the newer X50. I will be selling it as soon as possible because it is out of the return period for BB. So, in my opinion, if anyone reading this is thinking of a new X50, think again, save yourself some money and get a V10. On a final note I realized why RR said the V10 sucks. It is because he doesn't sell it, only BB does. Thanks Roy, for putting my faith in a sub-par high dollar unit that is a bug filled piece of garbage, that performs no better!!
