I guess it's hard to make a decent one. You can get scanners from about $600 up from china. Apparently you need an array of transducers which cost a bit.

I'm not sure why the Africans need a $2000+ butterfly scanner rather than this kind of thing https://www.aliexpress.com/item/Veterinary-ultrasound-machin... ?

I presume the Chinese one isn't as good. The images do look a bit blurry.
