The advantages of using a dog training collar are numerous, here are some examples.

Freedom without a leash.

Dogs are generally much faster than us and like to go for walks, so being always on a leash can seem a bit boring to them. With a training collar, you can go for off-leash walks safely. Obviously we must first start by working on the recall, we do not go into the woods overnight thinking that the dog will come back to us simply because he received an electrostatic. Once the recall is well mastered, you probably won't need to press the button on the remote control, just a voice command and the dog will return very quickly. The collar will still be very useful if a distraction presents itself, such as a deer. The training collar increases the learning speed and gives you security.

Security.

As mentioned above, the collar is a safety feature when the distractions are too high, squirrels, deer, or anything else, it becomes a necessary tool for the perfect recall. Safe if you want to walk or run without a leash, so that the dog follows you very closely.

Correct bad behavior.

We don't correct behaviors with positive reinforcement, so if your dog jumps on people, digs holes, barks excessively, the training collar will be greatly useful.

Faster learning.

You can teach your dog what to do or not to do, if you use a combination of positive reinforcement paired with negative reinforcement (training collar) the results will be much faster. With positive reinforcement alone it can take months to achieve something, with the mix of the two, very often it only takes a few hours!
