Talking 4" +. 3-1/2" is may work as well....

They seem hard to find, anyone know of small, regional manufactures that make them?

The obvious ones are the Strike King 8.0 & Ichikawa RC King Kong are the only two I really know of.......I think Megabass has one that is almost 5" and dives to 12-15', but not sure it's really a square bill?

Anyways, anyone know of other brands they like?

What diving depth do you want?

if it gets to 8' that's plenty good for me

honestly, even 6' is ok....more looking at size....

My first thought…and these are great.
Can square bill bounce them off cover and structure as deep as 10ft.
They cast like a rocket ship; can really launch them out there.

6th sense has oversized CBs in many depth ranges. Azuma too.

oh yeah....forgot about 6th sense too. Duh.

are those Bombers still sold? couldn't find them for sale anywhere? at least that exact model

These are good. They weigh 2 oz and dive to about 10' on 20# Flo. It dwarfs the SK 8.0

those look nice

H2O Academy brand makes some fairly large square bills if you can find them at the store. I have some that I bought several years ago.

You can step up to a Bullshad 4x4 as well

Deps 4.0 look nice too, but at a fairly hefty price tag for a crank bait. Ditto on the Bullshad 4x4, looks awesome, would hate to hang it on something tho! Would have to go diving...
