>>2570521>I want to cave dive with no experience. Don't, but If you're hell bent on doing it anyways, go with a buddy, bring a travel line with distance markers (white ring for 10 feet yellow for 50, red for 100, so 170' would be one red one yellow two white) on a reel so it doesn't turn into a rope monster. glow sticks, light and backup light, spare bottles to stage on the way back, and don't go in very far your first dive. If you have the money, consider a surface supplied rig like picrel so you can follow your hose back
