I bought this about a year ago. I upgraded to the 9 inch at Christmas. I used it for mega side imaging, mega down imaging and 2D. The unit has Hummingbird base maps. I modified the transducer bracket for my skiff, shown in picture. I have figured a new mounting kit in the price. They are about 28.00 on ebay but you should be able to mount it as is. I will take 475.00 shipped to lower 48. I can take PayPal gift option or add 3% or a USPS money order will work. Pictures are in simulator mode.. Thanks,Don
