Most people seem to go straight for an Engel tank for the static diving conversion of the U47. But water pump ballast systems can work well too, and are a lot cheaper. You will need to make modifications to the equipment tray, and use different batteries,as they're isn't enough room for those big lead acid bricks and a ballast tank inside.

i can't find it now, but i remember seeing a photo online where a gentleman replaced the forward SLA in his robbe with a "square" model airplane fuel tank of similar size, and used a small model airplane fuel pump to fill/empty that for his ballast tank.   very easy and inexpensive upgrade to a static diver.
