We used sleds in Hawaii for 2004 Nationals. It worked great & very fun to use as well. For covering large areas of grounds, they're invaluable.
The one in the ebay link is relatively easy to use, but is flimsy & broke on us the 2nd day of use!!! :vangry I like the design of Jon's one since (as we found out) having handles on each side wasn't the best design. As soon as you let go with 1 hand to equalize or adjust your mask, you run a very probable chance of doing barrel rolls
One of the coolest features of the sled is that you feel like you're flying! Hands outstretched & no kicking, I could get an extra 30 seconds of bottom time since I'm jst cruising along. No effort & recovery time was almost nothing. I do wish I had one of those swim-training snorkels that's in the middle of your forehead since if the boat goes too fast, it really pulls your snorkel to one side.
