Contact DeepCave
DeepCave is a small, independent, ad-supported site — there is no support team standing by, but a real person reads what comes in to support@kaevs.com.
A few things this address is genuinely useful for: a calculator that gave you a result you think is wrong (say which tool — the rope length calculator, headlamp runtime calculator, temperature layering guide, passage survey calculator, air & ventilation guide, or gear checklist generator — and what you entered); a tool you wish existed on the site; an out-of-date fact or broken link in the blog, learn section, or the Caves & Speleothems Museum; or a bug in how a page looks or behaves on your device.
There’s no fixed response time to promise, and no ticket number or live chat — email is read and handled as it comes in. If a question is really about the safety of a specific trip, a rig, or a cave system, a local caving club, a certified instructor, or the cave’s management authority will have a more authoritative answer than this site can give; DeepCave’s tools produce general planning estimates, not safety certifications, and the site isn’t affiliated with any caving club or guiding outfit.
Before writing in about a tool result, it can help to double-check the numbers you entered — a pitch depth, a lumen figure, or a tape-and-clino reading is the most common source of a surprising answer. If it still looks wrong after that, that’s exactly the kind of message worth sending.
