The name says it all

Great Lakes Tech Diving. It’s what I do. It’s what I teach. The Great Lakes contain some of the best shipwrecks in the world. The water in the Great Lakes is fresh and cold, perfect for preserving shipwrecks rather than destroying them. You can visit wooden sailing ships that have been on the bottom for 100 years that are still intact with the masts still standing. Many of these wrecks are beyond sport diving limits and require training in decompression diving and mixed gas diving.

My name is Rick Kruzel and I offer technical diver training tailored for the Great Lakes environment.  If you want to dive the Great Lakes, your training should reflect that. I have been teaching technical diving courses for over 20 years in the Great Lakes. If you want to dive the deep wrecks of the Great Lakes, I can help you achieve it!
