Hi guys,
I try to dive caves as much as possible few times a year but definitely not so much like some of you so I would like to use your experience in matter of getting to Heinkel restriction. If you could provide valuable info like average depth , max depth, exact distance, best way to get there and simply everything that will make our dive a pleasure and fun experience. I have done lots of Florida caves including Ginnie but never going further than Bats, and some point as far as approx. 1600 ft from the entrance. We will be diving sidemount open circuit (one of us rebreather) with scooters (two each).

Thanks for your help to determine either we will have what it takes to do that dive safely

Best for all.
Sebastian
