The comment by Roast Beef is a little abrupt - but has some truth to it but certainly not that harsh for those that make it. Those who really arent suited to the vocation of Commercial Diving will find it a hard go. There is a lot of travel, uncertainty and long hours.
BUT - and a really BIG "but" - those who are truly dedicated to becoming a professional in the industry by continually upgrading themselves in the latest technology (ie: ROV operations, Deep diving, construction, etc.) will find it a rewarding lifestyle that has no equal. If you truly want to be a professional (as in - THIS is what I do!!) - then you will be fine.There IS lots of travel, there IS lots of adventure, the IS periods of downtime, and, there IS lots of money to be made. Remember, you are buying into a lifestyle and a career. It is NOT recreational diving.
As far as Seneca UW Skills program goes, remember that it is a 8 month long course at college level - meaning you get credits that can continue on higher education if you so chose. And, being a diver is not the only path from that education, you could work for undersea service companies that doesnt even employ divers at all. Your education and training is only the first step. Continue educating yourself and move up the ranks. Personally, I used commercial diving to pay for school to become an engineer to end up running a large division of an international diving services company for 20 years. There are many like me. How we got to where we are/were took a lot of hard work, lots of travel ... and the many episodes of the uncertainty that Roast Beef mentioned. Being a lawyer or doctor has no guarantee of wealth or uncertainty either. I have friends in both professions who didnt have what it took in their profession either - and they are struggling!) - if you want it bad enough, you will find a way. It is NOT an easy industry. But - life has no guarantees anywhere. Suck it up - just do it!
I highly recommend Seneca and similar programs for what it is - a college that will give you the basics in the craft and an education that you can build on.
Good luck in your quest. If you want it and willing to work for it HARD, you will do just fine. It really isnt for everyone - but those that chose to do it and work for it, there is nothing like it!
