What certifications are required?

Normoxic trimix certification is required; CCR use is recommended. Operators expect logged experience on deep, technical profiles.

How deep do dives go?

Planned wreck profiles reach up to 200 feet; final depth limits are set by conditions and team capability.

Is gear transport available?

Yes — gear and tanks can be transported for a fee (around $250 per person); confirm arrangements before travel.

What are the group sizes?

Groups are limited to six divers total to maintain safety, communication and efficient decompression management.

How does weather affect the itinerary?

Weather, waves and port authority decisions drive site selection; expect contingency plans and possible site substitutions.

Are there insurance or health requirements?

Comprehensive dive insurance and medical clearance are strongly advised; operators may require proof depending on profiles.

Great Lakes Tech Trip: Deep Wreck Diving on Lake Michigan’s Preserved Ships | Scuba | Water Activities

Great Lakes Tech Trip runs a four‑day technical wreck expedition out of Milwaukee, Wisconsin, on the cold, freshwater shelf of Lake Michigan. Designed for advanced, trimix‑qualified divers, the itinerary puts teams on some of the region’s most intact wrecks — Prins Willem V, EMBA, St. Albans, Grace Channon, Walter B. Allen, Galliaper and the steely, storied Wisconsin — with dives to 200 feet that reward meticulous planning and tight team discipline. The scene begins on a working dive vessel cutting a low wake across flat, silvery water. Visibility in the Great Lakes can be remarkable; the fresh, cold environment preserves steel and wood, so railings, hull plates and cargo holds often sit precisely where they fell. A thermocline separates warm surface light from blue‑black depth; approach a mooring and the wreck slowly resolves out of that dark. That transition — the sudden geometry of decks and masts in clear, chilly water — is the trip’s signature moment. This expedition is technical diving taken seriously: normoxic trimix is required, closed‑circuit rebreathers are recommended, and teams run staged gas, decompression profiles and redundant systems. Divers should arrive with solid trimix planning skills, disciplined buoyancy control, and experience on big‑boat drift and moored wrecks. The operator limits group size to six, keeping teams compact and focused; that same crew culture turns complex profiles into clean, efficient dives. Beyond the thrill of depth, these wrecks carry regional history. They were freight ships, car ferries and steamers that moved goods, grain and people across the industrial Midwest — tangible chapters of commerce now sitting on a limestone and glacial‑shelf bottom. Surface intervals are spent prepping gas plans, calibrating deco computers and comparing notes on hull layout and penetration options. Practical details matter here. Weather, wave heights and port authority decisions shape which wrecks are accessible on any given day; contingency planning is baked into the schedule. The trip also handles gear transport for a fee, and operators are candid about fitness and certification requirements — they’ll tell you straight if you don’t meet the standard. For divers who chase precision, preservation and a sense of stepping into maritime history, the Great Lakes Tech Trip is a standout: deep, exacting, and run by a team that prioritizes safety and serious diving. Expect clear water, rigid procedures, and the rare chance to see whole ships preserved as if frozen on the lake floor — an experience that rewards training, patience and skill. Reserve during stable summer windows, carry comprehensive diving insurance and medical clearance, fly into Milwaukee Mitchell International with extra time to stage equipment, and arrive mentally prepared — this expedition rewards patience and exacting preparation with rare, preserved wrecks and intensely memorable deep dives.
