My buddies and I have had some success. I'll tell you how I do it, and you can adapt the techniques and configuration to your liking.
Equipment. Since I mostly night dive, I have a lot of lights. I use a C-8 for a primary, on a D ring mounted leash, an SL-4 for a backup, a MiniQ-40 on my mask strap for a head light, and a second MiniQ-40 for a backup backup.
I have my gauge on a retractor on the lower right side of my BC, and a spring lock bag on my right hip. I have a gauge mounted on my light, this works really well for me, and smooths things out considerably. I wear kevlar gloves.
Now, I dive mostly in Malibu. Big Rock, the pier, Corral, County line, Deer Creek. Finding the bugs come first. Water temp and habitat are the most important things. So, first find the habitat, then cover a lot of ground till you find a few bugs, in close proximity. Check the temp. This is where you'll most likely find lobsters in that area.
Start shallow. And I mean have your mask on, and be looking down, when you are still walking. I caught a 4 1/2 pounder in water I could stand in while putting on my fins.
Capture. I keep my light in my right hand, and the headlight on, sweeping from side to side. When I spot a probable keeper, I turn off the primary, and position myself for a left handed grab.
DON'T HESITATE!!!
(I'm right handed, for some reason, the lefty grab works for me. It's why my gear is configured the way it is.)
DON'T HESITATE!!!
Grab fast and firm.
DON'T HESITATE!!!
OK, you've got him in the left hand. Using your gauge on your light, pin him to your leg, and measure. Remember, it's between the horns to the back of the carapice. If the back of your gauge touches his tail, he's short, and on his way to freedom for another year. If the gauge hits the carapice, his new name is lunch. Drop the light, (it's on a leash, remember?), and grab the squeeze lock with your right. Open, insert lunch, and let the bag close on your hand. Let go of the bug, and pull your hand out. Grab your primary, turn it back on, and look sharp, where there is one, there are usually more.
(You got the message not to hesitate, right?)
The head light is important, even when you're wrestling with the bug, you always have light where you need it. When bagging, this is invaluable. And by turning off the big light, you reduce the chance of spooking of any other bugs that may be hanging around.
Repeat six times.
When you're done with the dive, re-measure on the beach. Ere on the side of caution, always, I've heard it's a steep ticket. Remember, the limit is 7 per day.
No snares or tickle sticks in California, the only tool you can use is a pair of gloves.
How well do these techinques work?
I have caught 7 over 4 pounds, 10 3 pounders, and 100 or so 1.5-2 pounders. My buddy caught one 7+. (See SoCalAJ's post, 'Bug Caught off Malibu', this forum.)
Good Hunting, see you on the beach!
