==Early life== Jake Koehler was born on December 8, 1991, in Huntington Beach, California. 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.<ref name="chitwood">{{Cite web |last=Chitwood |first=Tim |date=2017-01-23 |title=YouTube star mines Chattahoochee whitewater for online gold |url=https://www.ledger-enquirer.com/news/local/article128102719.html |access-date=December 22, 2025 |website=Ledger-Enquirer}}</ref>
==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.<ref name="chitwood"/> Koehler uploaded his first treasure hunting video in October 2015.<ref name="perelli">{{Cite web |last=Perelli |first=Amanda |date=2019-08-15 |title=YouTube creator DALLMYD has gained 8.7 million subscribers searching for 'lost treasure' underwater and found human remains, wedding rings, and guns |url=https://www.businessinsider.com/youtube-creator-dallmyd-searches-for-treasure-finds-iphones-guns-2019-8 |access-date=2025-12-22 |website=Business Insider |language=en-US}}</ref>
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.<ref name="chitwood"/><ref name="ripley">{{Cite news |last=Ripley |first=Joey |date=June 27, 2017 |title=From California to Phenix City, Jake Koehler finds his way on the water |url=https://www.wrbl.com/news/local-news/from-california-to-phenix-city-jake-koehler-finds-his-way-on-the-water/ |archive-url=http://web.archive.org/web/20210302224306/https://www.wrbl.com/news/local-news/from-california-to-phenix-city-jake-koehler-finds-his-way-on-the-water/ |archive-date=2021-03-02 |access-date=2025-12-22 |work=WRBL |language=en-US}}</ref><ref name="hale">{{Cite web |last=Hale |first=James |date=April 17, 2019 |title=Creators Going Pro: If Dallmyd Won The Lottery Today, He'd Still Spend His Life Making Treasure Hunting Videos For YouTube |url=https://www.tubefilter.com/2019/04/17/creators-going-pro-dallmyd/ |access-date=2025-12-22 |website=Tubefilter |language=en-US}}</ref>
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.<ref name="chitwood"/><ref name="gun">{{Cite web |last=Perelli |first=Amanda |date=2019-08-16 |title=When a gaming YouTuber found a gun while scuba diving, he decided to completely change his type of videos.

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.<ref name="niemeyer">{{Cite web |last=Niemeyer |first=Kenneth |date=2023-06-24 |title=A YouTube star rode in the Titan sub days before it went missing.
