What's a good training collar?

my classic 70 is so old it can’t be fixed. looking for a decent one out to 1 mile.

If you’re looking for a good training collar, I’d say it depends on your dog’s size and what you’re working on. For basic obedience, a flat collar or a martingale can do the trick if you’re consistent with commands. If you’re training for leash pulling, you might want to try a prong collar, but only if you’ve got some guidance on how to use it properly—it’s not about force, just gentle corrections. For remote training, I’ve had good luck with e-collars that have adjustable settings for tone, vibration, and static. They’re handy for off-leash training, but it’s super important to use them responsibly.
I found a great selection at ranchhand.store.
