Run the same sequence after fitting: mask, exposure protection, BCD, regulator, cylinder, computer and accessories. Ask your buddy to watch the releases and hose routing. Confirm the gas, pressure and computer setting. Then complete the operator’s normal buddy and safety checks.
Use four decision gates. The equipment must fit, operate, match the planned gas and be covered by clear terms. If one gate fails, pause. Ask for adjustment, replacement or a qualified explanation. Do not downgrade a concern because other divers appear ready.
PADI’s equipment-check guidance notes that regulators, BCDs and computers need authorised technical servicing. Rental equipment should therefore arrive through the operator’s maintenance process. Your handover check cannot replace servicing. It can identify poor fit, unfamiliar controls or visible problems before entry.
Write the final handover in one message. Include equipment accepted, model or size, existing damage, computer setting, gas, return time and agreed contact. This record makes later questions easier. It also gives the operator a chance to correct a misunderstanding before the dive.
If you feel unsure, tell the instructor and remain on the surface until the issue is resolved. Equipment comfort and understanding support safer decisions, but they do not remove environmental or medical risk. Follow qualified instruction and stop when something feels wrong.
