Hey,

As a North Atlantic wreck diver living on Long Island, NY, I am a BIG fan of split fins. First of all, Papa, I have taken the time to get my legs strong. I am a former Divison 1 Lacross player who is a competitive marathoner and triathlete. Strong legs I've got.

The advantages of the split fin are quite simple. Efficiency. Here in the North east, we have some strong currents. The opportunity to decrease strain thereby decreasing gas consumption is always welcome.

It allows me to kick half power and get same results, leaving a reserve for when I run into a strong current or miss the tides due to circumstances.

I started with ScubaPro Twin Jet, left them in the Bahamas and will now move to the Atomic Smoke on the water (great song BTW.)

I have a set of late 60's turtle fins and love them, but they are not always the best option. I find myself using them less often.

Split fins may be less durable (if not lost, my twin jets were in like new condition after 250+ dive) but that has yet to be proven. Any piece of equipment that is not properly taken care of will have a shorter lifespan. I also am a believer that in all industry there is a concept known as planned obsolescence. It's design. Cars, electronics, appliances, etc. They are cheaper to dispose of than repair.

So you are correct, they want to sell you another pair. Isn't that their job?

They are here to stay, and I urge divers to embrace the technology that comes with them. Over time, they will improve materials and design.
