I ordered a graph for my Charter Fishing Business. After 11 days I contacted company to find out where the unit was. I was told the transducer was back ordered so it wasn't shipped, which wouldn't be a problem but they failed to notify me. So after I called them and found out info, I ordered another unit. I needed to pay $80 for over night shipping because it's become very urgent I get this boat up and running! Guess What? It happened again. Called to find out where the unit was, oops it's back ordered, should be there in 10-12 days. Also no call from them. Unless you want to be frustrated do not use this company.
