I bought the FREEDOM4* system and used it for the first time this past Sunday. I found that the peace of mind alone was well worth the cost.
I purchased the unit from Rosalind (SeaChange USA) who was very helpful in my decision to purchase this product, as she answered all the questions I had about the system.
I feel people should be aware of the information about this product with the increasing number of shark bites we have experienced recently in Florida.
*FREEDOM4 is an obsolete product and no longer in production
