Mikko Paasi


Mikko is a passionate technical diver and explorer, always ready to explore and document the undiscovered underwater realm. Mikko started his professional dive career at the Ojamo mine back in 1998. Soon after, he moved to Thailand where he has been running Koh Tao Divers together with Krista ever since. Mikko found his true passion in technical diving, and as a result Koh Tao Tec Divers was born.

Mikko is an experienced technical diving instructor and teaches SSI, PADI, and TDI technical diving courses in backmount and sidemount configurations. He is a Kiss Sidewinder, Revo, and Xccr certified diver, and a SF2 eCCR rebreather instructor trainer and can train students all the way to hypoxic trimix 100m.


Over the past decade, he has focused on documenting the underwater world through his camera. Mikko has been the camera man in numerous documentaries and films, latest being the Untold Arctic Wars, and has also featured on the other side of the lens in the “Sukeltaja” ("Diver") documentary and "The Cave" movie. Mikko has also published a book “Sukellus valoon - Mikko Paasi and the incredible rescue operation”.


His expeditions have taken him to previously unexplored wrecks such as the Burma Maru and Trusty Star, HMS Gentien, and deep into the cave systems of Mexico, Sardinia, Norway and many others.


Putting his skills to good use, Mikko is a member of the Suratthani Rescue in Thailand. He is known from the Thai cave rescue operation which successfully brought a football team of 13 boys out of the Tham Luang cave in 2018. He is also a Member International of The Explorers Club NY, and was granted a 1st class knight grand cross from the King of Thailand, and a life saving medal from the President of Finland.


Given that Mikko is the one to keep the team spirits up and to put a smile on everyone’s face, and has a wealth of dive leadership and project management experience, it is only natural that Mikko is in charge of the diving side of most of our projects. He is the other founder of Bottomline Projects.


Fredrik Lindblad


Fredi is one of those people who just seems to understand it all. He has an unrivalled curiosity towards all things technical and a determination that drives him to never say no to a challenge.

Fredi is a serious asset to the team as he is an experienced professional photographer. He’s the person you want to have around when you’re wondering why your camera is doing this and not that. He’ll also spot something else you’ve missed: a mishap in your dive gear or that your T-shirt is inside out. Not sure where we’d be without him translating our gadgets for us.

Paying close attention to details comes in handy as Fredi makes an attentive buddy above and below the surface. He is an SSI assistant instructor and dives the SF2 eCCR rebreather, preferably in mines and cold water. Due to his passion for technical diving, Fredi spends most of his hours on land planning the next possible hours below the surface.

Fredi has a strong work ethic having worked as an entrepreneur for most of his life. Currently he’s running a car tuning shop in Helsinki as motorsport has also been in his life since before he could even drive. 


One of the many secret assets he has is being multilingual. He can set us right in fluent Finnish, Swedish and English. He brings a well-rounded knowledge of all things technical, excellent team spirit and friendly atmosphere to our team.
