So, THE BEST thing about a muck stick is that it allows you to maneuver/pivot around a small area without using your fins at all. You just stick the muck stick in the sand and use your arms to position yourself. You can use it to propel yourself off of the sand when you are finished looking at something and this greatly reduces the amount of silt being stirred up. If you are careful this will have very little impact on the environment....
If you are not using a muck stick in Lembeh, do everyone else a favor and ALWAYS be aware of your fins. Better yet stay 5 feet above the sand so you don't accidentally kick up silt. It is MUCH easier to do than you think.
Agree that "muck sticks" (as in this thread) are nearly necessary when diving in muck for anyone that want's to get close and see the critters without creating a cloud. A stick so one doesn't need to fin and controlled buoyancy to rise up away from the muck when finished will keep the area clean & critters from getting buried in the muck when the diver departs.
Managed to put a very large dent in the meaty part of my hand between thumb and finger with one. Had it clipped to a chest d-ring sat down in a panga with full gear - hand on the boat and muck stick point into hand. A very dull point but it still hurt quite a bit (understatement

). Was # 3 on the things that went wrong getting ready for the dive so called it. Still have the scar.
I've been calling these sticks "diver killers" for many years. In the past we used those expandable radio antennas for pointing to critters. Now we use these unbendable metal or fiberglass sticks for pointing out critters and stabilizing in muck - these are dangerous. I'm terrified that one of the guests on my trips (maybe me) will be injured on the dive deck, dive tender or when back-rolling into the water - stabbed with one of these sticks!! Every day on my trips I'm moving sticks on the dive deck so someone doesn't run into them. Divers tend to keep them clipped to their BCD when not in use, so a stick is often poking out into an area where people are walking and potentially falling! I've seen people with sticks in a sleeve stab themselves in the arm.
Couple of suggestions.
1. Everyone using a "diver killer" stick should be very careful with it! I won't try to go through all the possibilities for accidents - should be common sense, except to say that it should be somehow controlled (held in hand? attached to camera rig?) when backrolling into the water so it doesn't accidentally stab it's owner or the owner's neighbor.
2. Sticks with a big loop on the end or rubber/plastic handle are easier on the hands and have one end that won't puncture a diver.

I don't know the seller, have not purchased one, but looks worth a try. I'm ordering now.
We need new diver killers since a couple of guests in 2011 "accidentally" had 2 sticks fall into a dive bag when they left the ship. One belonged to a dive guide and the other to my assistant - really difficult for them to fall when attached with a clip to their BCD's

). They were the best sticks on the ship, one extra long with a rubber handle, the other stainless steel looped into a circle on one end. The dive guide's custom-made stick was seen diving with the guest in Bali by one of his co-workers - that's how we know where the sticks went!
