One of our all time favorite tools in dog training / walking is the long leash. 
It allows you to work on reliable recalls, and long-distance stays, and is especially useful with practicing loose leash walking.
Plus, it gives your dog more freedom to follow their nose when you go on sniffaris or go on a hiking trip, while still keeping them safely attached to you. 
It's perfect for dogs who may not be ready to be off-leash or for areas where dogs are required by law to be on a leash (which is almost everywhere)
