Just update to 2.41. v2.41 contains the same gain tables as 2.2 plus a minor improvement in the stitching. If you compare the two head to head I think you'll find v2.41 better, not dramatically better, but a hair better. I've been running both at the same time for a while now and displaying them side by side on a 16" screen. That's my 2 cents. And just for the record, I do switch the transducers back and forth on the GLS10 boxes to make the comparisons. You have almost the same thing with v2.33. It's v2.30 to avoid.
