ForceFin Pro?

Does anyone have any experience with Forcefin Pro fins? I picked them up at Last Chance Mercantile for $4.00
I looked um up online and they retail for around$250. Not a bad score huh?
 Looks like they are better suited for SCUBA than freediveing. Going to try them out this weekend. Curious to see how they do

I've had a pair of force fins for years. I primarily used them when I used to float tube fish. But they do work good for ab diving in thick kelp or around a lot of rocks.

Ghost thread revival, i have a pair fo the force fins,i have never  used them for free diving , but they are the only fin i wear scuba diving and  if they get lost  ill buy another pair,if you dont like yours ill buy them from you ,how about $5.00
