Compare software for your planning task
DecoPlan plans dive profiles, decompression and OC/CCR workflows. DecoPlan Cave is a separate planner for cave routes, equipment and gas. Compare their documented workflows with other planning tools below.
“Not documented” means the feature is not stated in the reviewed official source; it does not establish that the feature is absent. Documented workflows can differ in scope and implementation. This is not a ranking of safety or calculation accuracy.
Profile and decompression
DecoPlan: plan the dive profile
For open-circuit and rebreather planning, compare the profile and gas workflow first. The Cave route workflow is covered separately below.
On a narrow screen, scroll the table horizontally. Keyboard: Tab to the table region, then use the arrow keys.

Route and gas
DecoPlan Cave: plan the route and gas
A separate cave-route and gas planner. Compare route geometry, equipment, stages and the result you can review with the team.
On a narrow screen, scroll the table horizontally. Keyboard: Tab to the table region, then use the arrow keys.
| Task | DecoPlan Cave | Cave Planner | Subsurface Planner | MultiDeco | V-Planner |
|---|---|---|---|---|---|
| Route type | Out-and-back, traverse and circuit; the route type sets the gas rule. Source ↗ | Penetration, circuit and traverse. Focused on Tank Cave, with limited support for other caves. Source ↗ | Reverse the depth profile for the return leg of a cave dive. Traverse/circuit route modes are not documented. Source ↗ | Cave route geometry modes are not documented.

| Equipment and contingencies | Backmount, sidemount, rebreather/custom cylinders; suggested stage drops and emergency what-if checks. Source ↗ | Back gas and stages, drop/turn pressures; OC/CCR gas planning and bailout settings. Source ↗ | Cylinders and cave bailout at the turn point. Cave stage-placement recommendations are not documented. Source ↗ | Lost deco gas, turn pressures and RB bailouts listed. Cave stage placement is not documented.
