EVP Audio Recording vs. The Spirit Box

No offense meant to anybody but as a paranormal investigator who's been in the field for 35 years, I have tried using both the regular audio recorder and the spirit box. I still prefer the classic way of  getting EVPs, which is by using a digital audio recorder because an audio expert can always validate through a software if what you've captured is just noise, a human voice or a ghost voice. The Spirit Box on the other hand is fun to use specially if you're a thrill seeker, but since it gets signals and frequencies that produce lots of noise that can be mistaken as words, I dont find it reliable if you're into serious ghost hunting and paranormal investigation. It's a plus point as well if you want to look good (astig) on cam.
