Yes they are great to have I see all summer and hunting season. Fun to watch mouse bouncing in air etc. The only draw back is they are a great alarm system for deer.
Hearing is just as good as there nose. They come from different area then deer and have picked up my trail on several occasions and follow to my stand.
