I know that the larger the dome the easier it is to take split shot but is the difference between a 200mm (8") and a 230mm (9") dome negligible? I've also heard of some people building their own large domes strickly for split shots. Are there particular resources someone can suggest on a DIY dome for split shots or has anyone done it before?

To an extent it depends how calm the water is for the shot. An 8” will work for sure. A 9” is easier.

I’m tempted to say It’s one more easy. But I think Spinal Tap beat me to it.

What you need for the DIY is optical plexiglass/acrylic, 3D printer, waterproof sealant.

Some CAD skill will be needed aswell. I think hardest part is to find he plexiglass for a decent price and made into a dome shape.

Essentially you want minimum 12" dome, but something close to 20" could be done also depending on your needs.

If you do go the DIY route, please document it for others in the DIY section of the site.

If you want something large like this the large Matty Smith domes can be purchased they are rated only for use down to 2m and a very specific for splits. The price is around $AU1770 or about $US1100 for a 12"dome - a 17"is also available,
