I'm looking for a square bill that runs deeper that 6-7ft. Many of the deadfalls I target reach down to 10ft and I'd like to try one rather than a traditional rounded bill crank.

Only two deep diving squarebills I've heard of the are the KVD deep diving squarebill and this one from Lucky Craft:

I have tried the KVD and I just couldn't get the hang of it, I would much rather throw a Spro Lil John MD.

13 fishing gordito.  Dives 7 ft.  I've caught fish on mine.

Not 100% if this qualifies as a true squarebill, since it has a long (square) bill.  

Academy has one that is rated as a medium diver but it gets down pretty deep for a squarebill.

In the pile of fishing gifts from non fisherman is a cloud 9 magnum squarebill.

 

Yet to unbox it but supposed to dive to 10', however the thing is an absolute unit.

Thanks for the replies everyone.  I've used the SK and Spro baits and they don't get down quite deep enough on 10lb. fluoro. The only one that I know will is that behemoth 4in/ 1.5oz. that I actually have, but use for musky fishing. 

FYI ShirtFish, unless you weigh a lure down with SusupenDots to the point that it actually sinks, it won;'t get your bait to run deeper. Doing so would negate its ability to back out and up from a snag.

Curious why you want a deeper running squarebill. Better deflection?

IMO, a square bill will trigger strikes that a round bill wouldn't.  I've been using a coffin bill and seem to do better with it and I attribute it to the bill design. I just feel that a square bill will work even better.

 

Thanks to all that have suggested baits that run 6-7ft., but I'm looking to get a little deeper than that.
