Ditch the Calculators.
Automate the Audit Trail.
The only browser-based commercial dive planner built on entry-by-entry validated USN Rev 7 tables — with one ADCI/OSHA plan for your whole crew, live in-water bottom-time countdowns, one-tap print/email/text export, and full offline operation on any job site.
For Every Operation That Can’t Afford a Table Error
NavCommand was built by a commercial diver with real job-site experience — not a developer who read the manual. It understands what supervisors actually need under pressure.
Three Ways Manual Table Work Costs You
Commercial dive supervisors carry the weight of crew safety and company compliance simultaneously. Manual processes create three specific points of failure.
Generic apps use mathematical approximations of the Navy tables — close enough until an OSHA inspector or prime contractor asks you to show your work. NavCommand uses the actual published values, verified entry-by-entry. When the audit comes, your logs match the manual exactly.
Manually tracking residual nitrogen, surface intervals, and adjusted NDLs for a four-man crew across a multi-dive day takes time you don’t have and introduces calculation errors you can’t afford. NavCommand tracks every diver’s nitrogen loading in real time — you read the result, you don’t calculate it.
Filling out 24-item safety checklists, emergency contact sheets, and ADCI-compliant dive plans by hand after a hard shift cuts straight into your margin. NavCommand generates the complete document automatically from your planned profile — one tap from dive plan to compliance paperwork.
Plan the Profile.
The Software Writes the Plan.
Select depth and bottom time. NavCommand immediately returns your pressure group, NDL remaining, surface interval credit, and adjusted NDL for the next dive — pulled directly from validated USN Rev 7 tables, not calculated from a formula approximation.
The N₂ Diver Status Strip tracks every diver on your roster simultaneously. Supervisor, Diver 1, Standby, Tender — each shows their current pressure group in real time across the full shift. When Diver 1 finishes a rotation, their adjusted NDL for Dive 2 is already calculated and waiting.
When you’re ready to dive, tap once. NavCommand generates your complete ADCI/OSHA commercial dive plan — for one diver or the whole crew on one Team Plan — with the 24-item checklist, deco schedules attached, emergency contacts populated and signature blocks ready. Then print, email, text or share it straight from the viewer. The paperwork takes seconds, not an hour.
One Report. Live Status. Instant Export.
Three upgrades built from job-site feedback: the whole crew on one ADCI/OSHA plan, a live bottom-time countdown for every diver in the water, and a report viewer that sends the paperwork anywhere.
Every Diver.
One ADCI/OSHA Plan.
Stop filling out a separate plan for each diver. The Team Plan pulls every dive from today’s schedule into one document: the job site, emergency contacts, equipment checklist and supervisor signature once, then a row for each diver.
- ✓ Diver table: certification, depth and table row, bottom time, gas and ppO₂, repetitive residual time, deco, exit group and CNS%
- ✓ Automatic flags: expired medicals, ppO₂ over 1.4 or 1.6, CNS ≥ 80%, dives beyond the tables
- ✓ Every deco diver gets their own stop schedule and a banner naming them at the top of the plan
- ✓ Sign-off for supervisor, company rep and standby, plus a briefing acknowledgement line for every diver

Know Every Diver’s
Time Left, Live.
Tap Start when a diver leaves the surface. NavCommand runs a live countdown for every diver in the water: elapsed time, planned bottom time left, and time to the no-decompression limit.
- ✓ Pinned status bar: every diver in the water, most urgent first, visible wherever you scroll
- ✓ Scuba-tank gauge drains as bottom time is used, going green → amber → red
- ✓ Alerts with sound and vibration at 5 min, 1 min, time up and NDL exceeded
- ✓ Survives a reload or a phone going to sleep, and pre-fills actual bottom time when you log the dive
Print It. Send It.
Fix It in Seconds.
Every report — the dive plan, the ADCI/OSHA plan, the Team Plan and the Day Summary — opens in a built-in viewer with one toolbar. Edit takes you straight back to the form; change a bottom time and regenerate. ✕ takes you back to where you were.
- ✓ Print / Save as PDF for the project file or the client
- ✓ Email or text the plan to the office, prime contractor or crew from the job site
- ✓ Share the report file to Mail, Messages, AirDrop or Drive from your phone
- ✓ CSV and JSON backup of the day log for billing and records

From Dive Plan to Signed Paperwork in Four Taps
No forms to retype, no tables to cross-reference. Plan each diver’s dive once and NavCommand builds the OSHA dive record, the ADCI plan and the export for you.
Built to the Regulations Commercial Divers Work Under
NavCommand’s limits aren’t guesses. Each one traces to 29 CFR Part 1910, Subpart T or the U.S. Navy Diving Manual, Revision 7, so you can show an inspector exactly where it came from.
NavCommand is a planning and documentation tool based on the U.S. Navy Diving Manual, Revision 7, and 29 CFR Part 1910, Subpart T. It does not replace your safe practices manual, a qualified dive supervisor, diver training, or a calibrated dive computer. Regulatory applicability varies by jurisdiction and employer; consult your safety officer or counsel. Source: eCFR 29 CFR 1910 Subpart T
Everything a Commercial Supervisor Needs
NavCommand was built for the job site, not the classroom. Every feature solves a real problem that commercial dive supervisors face on multi-dive, multi-diver operations.
Every NDL, pressure group letter, residual nitrogen time, decompression stop, and total runtime verified entry-by-entry against the published U.S. Navy Diving Manual Revision 7. 12,067 independent tests — zero failures, zero discrepancies. No approximations. When the auditor asks to see your tables, you hand them the same document NavCommand was built from.

✓ Unlimited Users · Company-WideVerified Against the Same Manual Your Inspector Uses
NavCommand’s USN Rev 7 engine was validated across 12,067 independent tests in 22 harnesses — six real bugs found and fixed before first deployment. Every NDL, pressure group, surface interval, deco schedule, and runtime was verified entry-by-entry against the published U.S. Navy Diving Manual Revision 7. When an auditor pulls out the manual, your logs will match it exactly — not approximately, not within a rounding margin. Exactly. The validation harnesses are self-contained HTML files. Any inspector, supervisor, or dive medical officer can open them in a browser and run all 12,067 tests independently.
What Approximation-Based Planners Can’t Give You
Most commercial dive software uses a formula approximation of the Navy tables. That works fine until someone asks you to show your work against the published source.

Built by a Supervisor Who’s Run the Tables for Real
Scott Fontecchio is a PADI Master Scuba Diver Trainer, SSI Master Instructor, and ADCI-aware commercial diver with 40+ years of diving experience at Lake Tahoe and beyond. He’s managed multi-barge simultaneous lifts at 145 feet — three barges at once, coordinated with Parker Diving and Big Valley Divers — conducted ROV cable surveys for AT&T across 10 miles of lakebed, and operated under TRPA contracts for AIS and zebra mussel inspections.
NavCommand was built because he was tired of watching commercial supervisors manage multi-diver repetitive dive days with a clipboard and a printed table. The N₂ status strip, the one-tap ADCI plan, the validated tables — none of it is there because a developer thought it sounded useful. It’s there because he’s run those dives and knows exactly where the errors happen.
The validation report is public. Put your standard operational profiles into NavCommand and run them side by side with the published USN Rev 7 manual. The numbers will match — to the digit.
Put the Engine to the Test.
Then Put It to Work.
Try NavCommand free — no account, no credit card, no download. Load it on your phone right now and run your standard profiles against the published manual. When the numbers match, you’ll know it’s the real thing.
