Hello, I'm Gideon Long and welcome to Business Daily Meets from the BBC World Service.

This is where we meet people from the world of business from all over the globe.

Today, the final program in our series looking at shipwrecks and treasure.

And my guest is a multi-millionaire businessman who owns an island in the Bahamas, is a philanthropist,

and who spends his time scouring the seas for sunken ships

and treasure. We're finding ships that could be some of the oldest going back to the 1500s, all the way

up to Civil War wrecks, modern day wrecks. It's just littered with shipwrecks. We know there's

190 shipwrecks in our area that have been documented.

We've located in five years, 22 other wrecks.

Businessman Carl Allen, he tells us about the thrill of finding treasure on the ocean floor.

I get excited with everything, but when we find something big, it's, I feel like I'm having a out-of-body experience,

and the whole crew gets fired up, and when we get onto a hot streak and start finding stuff, it's like a bolt of energy.

I mean, it's just pure adrenaline.

Unlike some of the people I've spoken to for this week's programs, Carl says there's nothing wrong with being a professional treasure hunter.

I have spent in the last five years millions of dollars,

I have lost money because I don't sell artifacts.

Now, do I own some of this?

I do.

And look, I found it.

You know, I paid the money to get it.

So I'm not ashamed.

I'm proud of it.
