What is one characteristic of wreck diving compared to cavern diving?

In wreck diving, the conditions often involve specific environments where the unique structure of the wreck can significantly influence the use of dive gear. Many wrecks are located in deeper waters or have complex internal structures that require specialized equipment and techniques for safe navigation. The importance of buoyancy control, proper lighting, and potential penetration gear becomes amplified in these contexts. For instance, divers might need to use reels or guidelines to facilitate safe navigation inside the wreck, and the risk of becoming disoriented or encountering debris may necessitate more advanced gear for safety.

Other options do not accurately capture the distinctive characteristics of wreck diving in comparison to cavern diving. The presence of larger marine life is not a defining aspect specific to wreck diving; visibility can vary greatly in both environments based on location and conditions; and while both types of diving can have entanglement hazards, wrecks typically present more complex scenarios due to their structures compared to the more predictable environment of cavern diving.
