I'm a bit perverse. If I was diving your rig, I'd hire the rent-a-DM for one dive and see how they figure out managing it.Yeah... but not sure it's impossible. After all, Dutch ran for 40 years, allowing solo diving (with card and transponder). So it's certainly doable. And I would be fine if they required a buddy, it's not like it's solo or nothing for me. I only ever did OC solo diving there, anywaty.
But I'm not going to start hiring DMs or pressuring friends to supervise me.
