Great Lakes Technical Wreck Diving

New Dates for 2018 TBD : Coming Soon! 

Dive the best shipwrecks in the world. Lake Huron has some of the most preserved wrecks from different eras including wooden schooners from the 1800’s to steel freighters. Each ship has a unique story and history. Most of them sank due to fog and collision, ice, & violent storms. In this area we’ll dive 7 spectacular ships. They are preserved and intact in the cold freshwater. Diving them is like visiting an underwater museum and swimming along a piece of history. Artifacts can be seen on every ship and many of the sailing ships still have masts that are standing upright reaching up into 90ft/30m into the water column. You’ll be impressed with the clarity of the water (usually 100ft/30m) and the picturesque wrecks. This is a must for any wreck diver and photographer. We will be on 6 pack boats so we will limit the number of divers on the wreck at a time. This trip is for technical divers that are normoxic Trimix trained.  All of the dives will be 160-200ft / 48-60 meters and proper certification is required.

Dive Facts:

  • Best season to dive – June-August
  • Water Temperatures – 39f/4C at depth and typically thermoclines around 60ft/20m and 20ft/6m. Surface temps can be around 60f/15C.
  • Visibility is typically 100ft / 30m
  • There is ambient light at depth but a dive light is still needed
  • Most of the wrecks are 7-12 miles from the marina taking only 30-40min at most to get to.

Trip includes:

  • 7 nights lodging  on the beautiful Grand Lake. Based on double occupancy. (check in on July 1st, check out on 8th)
  • 5 days of wreck diving – 2 tech dives a day (160-200ft / 48-60 meters)

  • The wrecks we will be diving include the Typo, Kyle Spangler, Florida, Norman, Cornilia B. Windiate, Defiance, and Audubon all in the 160-200ft / 48-60m depths.
  • Detailed briefings of each wreck along with photography workshop included from Becky Schott

We will be on 6 pack boats so we will limit the number of divers on the wreck at a time. Bottom temperatures will be around 39F / 4C and a thermocline will give us a 60F/17C for decompression. Just to give you an idea most of our dives have been 25-40 minute bottom times with 30-50min of decompression (on ccr). I highly suggest doing some cold water work up dives beforehand and making sure you come with a dry drysuit and drygloves. Dress right and enjoy the dives even more!
