Infos on temps hatchlng

Hatching guaranteed male / female

Visited a local breeder that also customizes cages as I was ordering some cages for a breeding project. He also showed me around his breeding area and I was surprised that he confirmed on Temp control that successfully HATCHED males or females.
Meaning to say he could set his incubation at lower temps to produce females and higher temps of up to 84'c to produce 99% males.
He is breeding mostly breaded dragons n iguanas n veils.
Attach some pics of what he is selling.

I tried in google for this question but only found out that tortoises are able to be done this way.

Is this Possible???

Can someone shed some light on this?

Also what's the ratio like for breeders here like when their clutches hatch. Males vs females? Hope breeders and sponsors here can provide some Infos as well.

Based on some studies performed incubation-temperature-determined-sex is not seen in chameleons. I'm sure that if it was possible the big breeders would be using this technique with every clutch to get more males since they sell so much better. But that is not what we're seeing.
