Swimmer MOD 1 – Weed guards on our swimmers received a complete overhaul. They are now made of metal (in the USA!) and nearly impossible to destroy. I’d say after this redesign effort, it might be the toughest thing on our swimmer; we think that says a lot for the toughest swimmer on the market. It’s not a cheap fix and we are eating the cost of it…but we feel it is the right thing to do for our customers. We have tested our design thoroughly with exceptional results.
