I wouldn't go so far as to say extremely inaccurate. Definitely not conclusive, but with a good enough eye and experience it can be a fairly accurate way to tell, depending on the snake. Some are just too close to call, so if you really must know the sex, I'd check with other methods as well.Tail length may help give you an idea, but it's extremely inaccurate.

It does need to be an older snake, though. Babies aren't developed enough to see the differences, so if you're looking to sex a baby, I'd say find someone who can pop or probe for you.
