I'm currently taking a Karen Pryor trainer clicker class and just tried the clicker in the link below. I like it better than the box since it's easier to click but it's quieter so in a loud place not as audible. It is better in class so clickers everywhere aren't as distracting. I also have another dog that did bark at deer and elk when we moved and I got a digital clicker for her alone. I didn't want puppy cueing on it but I did train the older dog and it's her sound alone. Worked like a charm. Clicking two dogs has always been confusing for them and me. For distance and loud places the box still works best.
