What is a key feature of the open GTG tunnel?

An open GTG (Good Time Games) tunnel is characterized by having no turns, which is a key feature that sets it apart from other tunnel configurations. This straightforward, linear design allows dogs to navigate through the tunnel without the challenge of turning, making it a suitable obstacle for training sessions or competitions. The lack of turns encourages dogs to build confidence as they quickly learn to enter and exit the tunnel, which is essential for novice handlers and their dogs. This design element emphasizes ease of use and helps focus on the dog's ability to move forward through the tunnel. Other choices may relate to the overall attributes of agility equipment or the experience level of the handler but do not specifically address the fundamental design aspect of the open GTG tunnel that contributes to its purpose in training and competition settings.
