I’ve used Paterson tanks for processing my B&W film for over 50 years. My issue has always been temperature control and consistency. I’ve thought of a Jobo on nany occasions but they’re big, expensive and use a different tank and spiral system.
I signed up to the AGO when it was a IndieGoGo campaign. For me the advantages are cost, size, a clever way of compensating for changes in temperature, uses less chemicals and uses the Paterson tanks and spirals I’m familiar with.
I’ve used my AGO processor many times now with all sizes of Paterson tank right up to the Multi-reel 8. Works so well.
