Higdon Outdoors is offering a service where you can send us the entire swimmer/pulsator/or any Higdon motion decoy(s) and a payment of $50.00 and we will check all your parts and replace any faulty parts with brand new parts and ship it back to you. After we do this the warranty for the product is reset. We offer a 6-month warranty on our motion products when bought new or after the product is refurbished through the above process. ONLY included parts we receive will be tested and/or replaced. Duck dunkers are no longer a refurbished option. Turnaround time to complete your unit(s) is around 10-15 business days.
