Going through DM eLearning with PADI and a number of the assessment questions require the use of the eRDPml. I'm getting less and less impressed by PADI over time but this is a new low. Do many people own this silly device? If PADI was at all serious about it being useful it would be an app, not a 70s-vintage calculator. I looked on-line for a calculator as well but there are none. What's the story here? Do most DM candidates take the assessment with an instructor looking on that has one of these devices?
