Reference excerpt

Jake Koehler (born December 18, 1991), known online as DALLMYD or Scuba Jake, is an American YouTuber known for his treasure hunting videos often involving him scuba diving.

Early life Jake Koehler was born on December 18, 1991, in Dahlonega, Georgia, but grew up mostly in Huntington Beach, California as a child and teenager. His father was formerly an Army Ranger who also taught science at Shaw High School. He has two older brothers and a younger sister. Koehler graduated from Huntington Beach High School in 2011 and enrolled in Golden West College, taking courses in English, history, art, and ceramics. He later dropped the former two classes, eventually dropping out of college entirely. Koehler then moved to Columbus, Georgia with his parents, who gave him five years to prove that he could make a living off YouTube.

Career Koehler started his channel in 2011, mainly posting Call of Duty and Grand Theft Auto content. By the time he moved to Georgia, he found that his videos were not as successful, so he decided to pivot to making outdoor content relating to the Chattahoochee River. He already had previous experience with watersports, surfing often in his hometown of Huntington Beach and also being one of the first people to surf down the Chattahoochee's Powerhouse rapid. Koehler uploaded his first treasure hunting video in October 2015. Koehler records his scuba diving with a GoPro; he also keeps tools with him to free himself or animals trapped in fishing wire. He mainly searches for treasure at the end of the two main rapids of the Chattahoochee, where many of the items dropped by rafters end up. He returns the lost valuables he finds to those who can establish ownership of the item and cleans up junk from the river. In December 2016, Koehler's videos, especially one in which he found a gun in the river, went viral, nearly tripling his subscriber count from 480,000 to 1.3 million in two weeks. In 2018, the city of Columbus, Georgia named October 2 as Jake Koehler Day, recognizing him for his efforts around the Chattahoochee Valley. In 2023, Koehler was invited by OceanGate CEO Stockton Rush to board the Titan submersible on its Mission III to vlog the wreck of the Titanic. The submersible did not end up diving on this mission due to poor weather conditions, a ghost net destroying some of the sub's parts, and the motor controllers malfunctioning. On its first mission in which it actually dived, Mission V, it ended up imploding and killing all five passengers. Koehler later uploaded his vlog to YouTube documenting his close call. In 2025, he appeared in the documentary Titan: The OceanGate Disaster to give a testimony of his experience.

Worked examples

Example 1 — a first encounter with Jake Koehler

Start with the simplest possible case. Write down what Jake Koehler claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Jake Koehler before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Jake Koehler ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Jake Koehler

In research: Jake Koehler appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Jake Koehler in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Jake Koehler is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1991 births, American YouTube vloggers, American underwater divers, so understanding it makes those chapters shorter.
In everyday life: Look for Jake Koehler outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
