Spreader bars

Do any of you use spreader bars with much success? I’ve always thought a couple of bars would raise fish here, but it seems to be the go-to tool for people where they target tuna.

I use a squid spreader bar on one side of the spread and a daisy chain on the other. Tend to get a lot of strikes on the bait placed behind the bar.
