Redbone Coonhound Off-leash

Has anyone ever had success hiking with their coonhound off-leash?

I have really good days with my girl and then I have bad days. She has an e-collar and has been properly trained, plus GPS tracking but when she catches a fresh scent she goes into a frenzy and gets really bad tunnel vision and nothing seems to work.

Should I just give up and keep her on a leash or has anyone got any advice?

She's 4 years old and getting more and more defiant with scents and now she's discovered deer and it's giving me grey hair. 😅
