Seeing as nobody is willing to take the time, I've gone and did a quick bit of research on the matter.

Fishing level 30:
Location: Knightwell (West Ronfaure)
Pole: Halcyon Rod
Lure: Robber Rig
Casts: 244
Items: 231
Fish: 8
Nothing: 5

Location: Knightwell (West Ronfaure)
Pole: Composite Rod
Lure: Robber Rig
Casts: 286
Items: 229
Fish: 53
Nothing: 4



Fishing level 40:
Location: Knightwell (West Ronfaure)
Pole: Halcyon Rod
Lure: Robber Rig
Casts: 319
Items: 272
Fish: 44
Nothing: 3

Location: Knightwell (West Ronfaure)
Pole: Composite Rod
Lure: Robber Rig
Casts: 191
Items: 122
Fish: 62
Nothing: 7


Conclusion:
Yes, you can catch fish with this item.
Yes, your level does make a difference in bite-rate
Yes, different rods do make a difference


Weird enough, but only with Composite did Red Terrapins ever even bite. On the other hand, only with Halcyon did Crayfish ever bite.
I didnt release a single catch, except for monsters.
I wouldnt suggest using this lure ever, if yourgoal is to single out a specific fish. Maybe around lvl 80+ the bite rates will be sufficient enough to try single out any specific catch, but even so, this lure is designed for catching mostly anything that exists in any particular spot.
Your level and gear will determine what bites and what doesnt.

actually, i've found the robber rig useful in fishing up rusty leggings in north san d'oria in front of the castle. I'm not sure about the leggings, you might wanna double check on that... but last i checked rusty subligars sold for about 8k a piece because of the ninjutsu quest thingy in norg. Considering they want you to hand over 10 of the abnoxious little panties, the investment might be worth it to a ninja. IMO anyway....

Here's what I've heard...

You catch more fish with Robber than Rogue. Rogue has a wider variety of fish it can catch, but the bite rate of fish is extremely low.

In other words, Robber is better at catching Shall Shells and Vongola Clams, and Rogue is better at catching Rusty items.

don't get this newb, waste of money, won't get anything O.o, sabiki is ok though

I just bought this Rig... and am pretty... well... not satisfied. I mean... I have casted my line 112 times... caught 3 Rusty Buckets, 2 Crayfish, 3 Rusty Caps, and 1 Sandfish in Rabao. Not even a single bite from a Moat Carp. I was pullin in 5 stacks out of every 10 stacks of Insect Paste out here, along with 5-10 caps... so what did I just spend 20k on?

I am gonna run to North Gus, and see what kind of Sexxy Carping action I can dig up... but so far... I am not impressed at all.

Oh ya, my fishing skill is 35, and I have full gear, and a composite rod.

ok heres my deal. im a brand new fisher (level 3) and i just bought a composite rod, and a sabiki rig, hoping to catch some moat carp. but i find out that sabiki's dont catch carp. i was told a great place to fish is Port sandoria. wehre is a good place to fish, with this lure, if i can even use it yet. what are my options, should i just go with incect balls?

You the Man AIRSPIRIT!!!!!!

I took your advice and bought the shizit for 20k or so... and went to N Gusta and got like 4 stacks in an hour!!!! AN HOUR!!!!

Kept on fishing I walked to the mog house with around 10 stacks and easy 40k for a day of fishing..although the NEXT day I decided to take the "sexy carping action" the my sweet spot the knightwell... and I caught EVEN MORE CARP!

The Line NEVER broke in 6 hours ... EVER!! and caught another 3 stacks in an hour.

Ever since then I've been fishing at the knightwell in West Rondaure and it's safe to say that you wont lose the rig there and IMO is the best spot for carp ever...

The Robber Rig can be used to catch up to 3 Moat Carp at a time in Bastok Markets... I am a lvl 20 Fisherman and I catch stacks on stacks, use it with a Composite Rod and you are set for life. Note: Moat Carp can also be turned in for the Lu Shangs quest, so using a Robber Rig can make this process 3 Times as fast.

Black then white are, all I see, in my infancy.
Red and yellow then, came to be, reaching out to me.

I was wondering what guild points are? And where you trade them in at

You would think this rig is for catching items.
