If he's skilled and if his equipment is up to date... then 15 weeks can yeild a very accurate scan for gender. I had my friend scan me at 15 weeks +4 days and she CLEARLY showed me my boy's twig and berries! 
When I had my 19 week scan a couple of weeks ago, my doctor confirmed that I was, indeed, having a boy. FWIW, a GOOD ultrasound tech will NOT "guess".... and will only give an answer if they are VERY sure they are correct. (My friend said that unless she was 98% sure, she will NOT say either way!)

Yes, that's true I suppose. It just so happens that at every US from week 15 on (had 2 at 15w, 1 at 16w, 17w, 19w, 21w, etc) every US tech said the same thing (and I didn't tel them anything first). Just reporting a personal experience.
