Any dive shop should have them Chris. Not sure why they still allow hand capture or nets either for that matter. The use of a padded snare and tickle stick are fairly lethal in my experience. Most importantly, they do far less to damage, amputate legs, etc. than either other method of capture. You have less chance of getting caught yourself by a moray or ripped up on spines and rocks.
If you prefer to mail order, they can be found at:
