A personal submersible? Don’t mind if I do! What’s that, do I have $US5.5 million handy? Uh, why don’t we assume I do and you can just show me around?
When it comes to finding the perfect submarine for one’s personal use, it doesn’t get much slicker than Triton Submersibles’ range of vehicles. Sure, you’ll need a few million dollars to spare if you want one of your very own, but when did that stop anyone?
(OK, it stops everyone.)
For those with $US25 million to burn, you can pick up Triton's deluxe model, the 36000/3. It can take three people (pilot included) down to depths of 11000m.
If spending tens of millions is out of the question, Triton does have cheaper models, like the 6600/2. 2000m is the max on that one, but it can handle a pilot and passenger and will only bankrupt you seven or eight thousand times over.
Time to start saving.
