Looking for help with installation hds 10 lowrance

[Herefishy9995]

I need help installing my new fish finders on my boat and was wondering if any locals might have expierence with the new hds 10's. The last boat shop charged me a mint to install them and was wondering if any of you would have any suggestions on who would be good. I have 2 hds 10 with structure scan. Thanks
