Not sure if u can hear it but at day 2-4 u can see it if u candle it cuz u see a spider with a heart beat heart is bigger then the body at that time
About Doppler if it has gell I'd say no and any thing that needs a gell is an infrared that picks the pace of sound (I think u know better about a Doppler but I think it has infrared) and infrared is super damaging to the embryos development
Not to be pedantic, but they do amplify sound.Quote:
Stethoscopes do not amplify, they only transmit sound, unless you have a special stethoscope that amplifies. So, you will very likely not hear anything that you could not hear by holding the egg up to your ear.
