I have been using the ISHOF SafeSwimmer for a while now, but there is a now another open water safety product on the market. The GOAT Gear Aquaspotter consists of a lightweight flagpole and a bright orange flag that attaches to a neoprene belt. The neoprene belt also holds a waterproof bag that is large enough to fit a cell phone and car keys. (You can read more about the Aquaspotter on their website).
I bought an Aquaspotter last week and have been waiting for an opportunity to test it out. This morning I was finally able to take it for it's maiden voyage in the super salty water of the Great Salt Lake. I met three other swimmers at the Great Salt Lake Marina, all very curious about what this thing might be.
The neoprene belt is very comfortable and I hardly noticed that I had it on. I was worried that in the salt water it would start to chaff, but I didn't have any problems with it at all. I put my car keys and my wedding band in the waterproof bag and also could have easily fit my cell phone.
I have to admit that when I first saw the Aquaspotter, I thought it would be awkward to swim with. It has a pole and a flag that attach to the neoprene belt and stick straight up in the air while you are swimming. I was surprised that I hardly felt it at all.
Here is some video of the device in action from their website:
The other swimmers all said that it was very easy to see and even started to sight off of the Aquaspotter flag instead of the buoys.
