Dual A-scope

[Sabatti]

I have a 1870 and updated to a 1871 several years ago. The 1871/1971 have a dual A scope, one on the bottom lock (split screen) and one on 0 down. I have looked at other furuno models and have not seen the dual A scope on any other models? Would like to get a portrait screen e.g. 588 but need the dual A scope to see bites on the bottom when vertically jigging. Any ideas? Thanks
