What is a muck stick really used for? The only time I dived with someone with a muck stick was in Bali when the dive guide was using it to force the poor frog fish out of a hole and lift the spanish dancer to show us it can swim which I found rather annoying. I'm assuming there must be a proper purpose for a muck stick
A stick isn't necessary to abuse wildlife, but there are uses I consider legitimate. Perhaps the most important is to help a diver position and move him/herself in difficult places with lots of live corals, sponges, etc. There are reefs so alive that it's difficult for a gloved hand to touch anything without the risk of damage, but there are usually at least a few small areas of rock or dead coral - big enough for the end of the stick to be be placed to stabilize the diver or assist with movements. I've also used mine to anchor myself in sand in a strong current.
Turning over rocks and rubble (searching for boxer crabs and other crustaceans), etc. falls within the pale as far as I'm concerned. I don't wear gloves except in very cold water, so a stick is good for this. I've also used my stick to gently reposition a crinoid out of the way so I can shoot something behind it. (It goes back again), to softly stroke crinoids on their feet to induce them to open their arms for a quick glance or shot of a clingfish, squat lobster or commensal shrimp living inside. To attract octopus and stomatopods to come out of their holes, which sometimes works. On abyssal walls infested with crown-of-thorns, to stab cots and then carry them out over the deep and let them go. And once to encourage a stone fish to move to deeper water. (It had been resting in the sand in very shallow water near where local kids were swimming and wading barefoot.)
Sturdy, decent-sized stainless steel rods are better than radio antennas for use in stabilizing or epositioning oneself, though a sturdy chopstick (which was always Larry Smith's favorite) will do.
