Divers Institute of Technology

At DIT, we don’t just train underwater welders, or any other particular type of diver. We care about creating a well-balanced diver, and we will train you to succeed in many aspects of commercial diving. You’ll perform deep dives to 165 feet, employing both in-water and surface decompression. Your instructors here are industry experienced and knowledgeable in the field, and our intensive, hands-on, and measurable curriculum is designed so that once you graduate, you are prepared to excel.

Thrilling Adventure

With more than 50 years of hands-on training, soar 165 feet deep into Lake Union and feel the adrenaline pumping through your veins as you weld underwater, drill holes in concrete, use hydraulic tools, underwater chainsaws, and have other thrilling experiences that our 7-month program offers.

Helping You Succeed

At DIT, we are committed to training quality divers so that when you graduate, you’ll enter the diving industry with the knowledge and skills needed to succeed in your new career. When you attend school here, the bulk of your surface supplied diver training will be conducted in open water, giving you real world experience that can’t be replicated in pools, tanks, or quarries.

Our History

We’ve been Veteran Owned and Veteran Operated since our inception in 1968. We were the first, and are currently one of only four programs, in the United States to offer an International Certification, the CSA . This allows you to work globally, and can open up many opportunities for you in your future career.

Here at DIT, we ask a lot of you, and you’ll be expected to challenge yourself, but we’ll be here to help you each step of the way!


Our mission is to provide advanced technical training that produces the most qualified, skilled professionals in the constantly evolving underwater marine industry. To fulfill this mission DIT is guided by these two uncompromising principles:

  • First and foremost we practice an unyielding commitment to safety. Whether in training or operationally deployed, job safety analysis determines every action in dive operations. Our instructors expect each student to embrace this same commitment, and we take pride in providing them with the knowledge and skills to adhere to these expectations.
  • Our second principle is gainful employment and advancement in the commercial diving industry. Through constant networking with industry professionals, we are able to determine what skills and certifications the dive companies desire in new divers and dive tenders. Divers Institute is here not just to get graduates a job, but to help them throughout their career years after graduation.
