Using equipment for the first time during a dive inherently carries the risk of increased likelihood of failure or improper use. When divers are not familiar with the functioning and features of specific gear, they may struggle to operate it effectively. This lack of familiarity can lead to critical mistakes, such as incorrect adjustments or failure to respond properly in an emergency scenario. As a result, divers might not be able to utilize the equipment as intended, which could compromise safety and overall dive experience.

In contrast, the idea that all equipment is reliable underestimates the potential for user error and mechanical failure. New divers may feel confident in their gear's reliability but may not be aware of its specific operating procedures, which are essential for safe use.

The notion that using unfamiliar equipment enhances the diving experience or improves buoyancy control is also misguided. While proper equipment can indeed enhance a dive, using it without prior experience can lead to anxiety and distractions, taking away from the enjoyment of the dive and potentially leading to dangerous situations. Therefore, it is crucial to practice and become familiar with diving gear before using it in actual dive scenarios.
