Do not buy from this outlet. They are not affiliated with Humminbird, but give them a bad name.
I purchased a 581I DI Combo but what was delivered was a without the DI(down imaging) feature. When I contacted what they call customer service I was on hold forever and offered nothing but to return it at my cost and be re-imbursed. I spoke to two different "suprvisors" who still offered no real concern or help. They each said they would send me the correct unit but never billed my credit card or sent me an order number.
They SUCK!!!!!!!!!!!!! After 5 days of attempting to get an explanation or some action(not even a return phone call or email. I left a message to cancell the order. Then when the incorrect unit was returned to them they credited me only 80% of the original cost.
Called them again and got a promise......for what that is worth.... to credit me the additional amount. I am still out the $18 it cost me to sent it back. I was counting on getting the fish finder for a weekend fishing trip but they screwed that up.
I talked with a customer service rep from Humminbird who reported that complaints on this store were common. Please go elsewhere for your purchase!!!!!!!!!!!
