Cloak And Dagger

The Cloak and Dagger Spy Watch is an unlockable gadget for the Spy, replacing the Invisibility watch in the 'PDA' slot. This sophisticated digital watch, sent express from the mail-order supply company Mann Co. (a subsidiary of TF Industries) enables the user to recharge the cloak meter indefinitely (even when cloaked) by remaining stationary in exchange for the ability to recharge it with ammo and dropped weapons. The Cloak and Dagger will not automatically decloak you if the meter runs out, instead you will remain partially cloaked (as when touching an enemy) until you stop to recharge or deactivate it. The cloak meter will not recharge while stationary and cloaked underwater.

Note: Due to the mechanics of how the C&D charges and depletes, neither a continual crouch-walking strategy nor a run-and-wait strategy offers any direct benefits in terms of distance traveled, assuming the spy remains fully cloaked the entire way. A given amount of cloak-energy will allow you to travel a fixed maximum distance regardless of how fast you move, and energy is recharged at a constant rate, leading to a constant average speed.
