Quinte Fishing

I own a 7 year old Humingbird fish finder on my boat. I believe its a 520 HD ci. It's put away for the winter. I have been using for just depth and fish finder but now would like to start following some contours also. I'm looking to get a chart for the Bay of Quinte and HayBay area on an SD card to put into my unit for the spring fish. Who would I contact for that ? I'm not cheap but a copy of one would do me.
Thnx in Advance

It's not possible to copy a Navionics or other manufacturer's chart chip! If you only fish in Canada then the Navionics+ Regions chip (Canada & Alaska) is the best one for you! You will have a year of free updates with this chip.

Thnx ...I just ordered it.
