Finding baby’s heart beat at home?

I’ve had some people say it wasn’t safe to use an at home machine to locate babies heart beat. Why is that? I really wanted to buy on around 12 weeks or so. I’m 8 weeks right now. But just want to hear why maybe it’s not a good idea? If I do buy one I’ll be using it every day I feel like (not really lol) 😂
