    Jobo tanks are still being made.
    Not cheap - but are out there and can be bought NEW.

    700ml of Xtol 1:3 in a 3010 for all the B&W film I shoot. I never level the tank on my Uniroller base as the tank tends to walk off. I always have the lid end high with the lid bearing on the rollers.

    I use the 3005 and 3010 tanks and after discovering what you did, I started using a minimum of 600-700 ml of developer and have had beautiful results ever since.

    Looks to be the consensus here.

    Jim,
    I'm guessing all most of the jobo expert users here are relying on visual evaluation. I did a test using plus-x and t-max developer with 300ml, 500ml and 700ml. In all the cases I found variations of density in all axis (depth, radius and rotation, invisible to the naked eye) and it's worst than expected (9 locations per sheet, half inch from the border). I'll post the delta-density numbers later.

    Make sure you qualify your results using a real name and contact info.

    This is very interesting as I have similar experiences to the others who've had no problems with their 3010 drums. I usually run close to a litre for a full load. Minimum I've used was around 500 ml.

    Just asking but is this data from an unexposed neg ?

    The ironic thing is these drums have been around for twenty plus years, used by folks like John Sexton etc and claimed to be virtually the best way for home darkroom users to achieve flawless processing results. I have used the drums for about that long and done thousands of negatives, hundreds of tests and the issues are traceble to user error. In my book, soon to be written Its the claiments responsibilty to document the issue in such a way that it can be repeated consistently. That said the drums may not be the method of choice for all developers and circumstances....so qualification is really a requirement- at least in my book to be taken seriously.
