Lost the hearing and got tinnitus in my left ear last year. I tell people that going deaf wouldn't be that bad if it wasn't so loud! And deer hunting is when it's the worst - when it's supposed to be quiet and peaceful with just 'small' noises. To the OP, the only thing I can add would be to try to pattern the deer, if possible, so you're fairly certain where to be looking. One place I hunted, all the deer moved East in the morning (from golf course/houses to state park) and West in the afternoon (back out of the park). Maybe set up so you have lots of cover behind you.
As far as set-up I try to always account for wind and path of travel. In 40 years of hunting the one thing I've learned is deer will do exactly what you don't expect. BUT every now and then "even a squirrel finds a nut in the forest". Sent from my iPhone using Tapatalk
I have had hearing problems for many years (age 61 now) and just last year I got hearing aids. They told me that I would be able to hear the deer now. The only problem is that I did not see a single deer while hunting this year. The aids have been able to make it so I hear more, sometimes too much so I turn them down or off even. I have heard other animals while I was in the woods so it has improved. My tinnitus is not real loud so I do not use the tinnitus blocker on the hearing aids anymore. Hopefully it won't get louder.
I also have Tinnitus in both ears and have lost a lot of my hearing. I can't pinpoint direction either. I have spooked my share of deer because they sneak up on me. I use the Walker Game Ear Muffs and they help me. Still not as good as people with great hearing.
