Pat the scallops dry with paper towels. Removing excess moisture helps the bacon crisp and prevents steaming.
Cut each bacon slice in half to make 16 shorter strips. Wrap one piece of bacon around each scallop and secure with a toothpick if needed.
Season the wrapped scallops evenly with Old Bay seasoning and black pepper.
Lightly spray the air fryer basket with olive oil spray.
Preheat the air fryer to 400°F (200°C) for 2 minutes.
Arrange the bacon wrapped scallops in the basket in a single layer, leaving space between each one for airflow.
Air fry at 400°F (200°C) for 8 minutes. Flip the scallops halfway through cooking.
Continue cooking for 2 to 4 more minutes, until the bacon is crisp and the scallops are opaque and cooked through.
Remove carefully and serve immediately while hot.
