I have the probing tools available but I'm in SA which is too far :/

But I've found that if it's sold as a male then it usually is. This is because most times the female is worth more, so if you did get a female by mistake, then it's your win because It's worth more. The times you have to be careful is buying a female, because the male can be way less or half price, you could be had easily if inexperienced.
