Excellent training method, very straight forward and very popular for pointing dogs. The Delmar Smith approach with the silent command is an excellent read. Many talk way too much to their dogs during training.
There are lots of different training methods that will work. Review a lot of them and stick with one. However, don't jump from one method to another with your dog, it will confuse both of you.
Hardest part of training for me is getting pigeons or birds to train with. Pointing dogs need lots and lots of birds for training. The problem with pen raised birds and pigeons is when they are poor flyers. You don't want a pointing dog catching birds when you are training him. The more wild birds you can get into the better.
Don't ever give a command you cannot enforce.
It's usually real tough to unreach a dog something like being guy shy or other issues if you don't expose and/or introduce your dog to things and train him correctly.
Be fair to your dog. Never get angry. You want your dog to be successful in each training, stop on a good note. Train in short time spans. Be consistent.
Many of these techniques are great for raising children too.
