I'm in my late 60's and have a hearing loss. I have hog hunted with some younger guys that seem to have outstanding hearing. They always warn me when wild hogs are nearby. I have a thermo imaging scope which is extremely valuable but wish I could hear the hogs before seeing them. I have been looking at a Hausbell listening device that uses a plastic funnel and a microphone and amplifier. Not real expensive. Wondering if this device would be worth the expense and lugging it out to the tree stand. I'm looking for something to make me hear even better than the younger guys. Is that possible and practical?

I'm I better off turning up the volume on those?
