My dad used gaffers tape for many years in audio-visual applications (things like taping cables across the floor) and it's perfect for anywhere you don't want to leave a sticky mess afterward. It holds great and doesn't leave any residue when you remove it. It can also be torn to any width or size by hand. I've used it for multiple things with my detectors including covering the speaker on my Pro-Pointer, taping the doors on my DeLeon battery compartment and wrapping where the rods connect on my detector that doesnt have a screw type locking mechanism.
You can find numerous listings for gaffers tape on eBay, and I know Grainger also sells it. It's not cheap. Depending on where you buy it, $10-$25 per roll. But a roll lasts a long time. I use 2", but it also comes in 1" and 3". I use black, but it comes in all different colors.
