Hey all,

I need to replace my existing finder, as it now turns itself off on a semi-regular basis while in use. I’ve gotten my money’s worth out of it, but now want to make sure I understand what my options are moving forward wrt keeping my existing maps etc.

I have a Hook2 5 split shot, and it has worked fine for my needs and budget. Looking online I am seeing a lot of variability and less overt clarity on what I want and what I hope to do. I’d like to keep the split shot as I have transducers mounted on both my kayak and small PB. I need coastal mapping. I am seeing a ton of ones listed for US lakes, I really don’t fish freshwater much at all. I bought the Navionics package for my old one and have the mini SD card that slots in the body of the FF.

Questions:

- Can I buy the same model (if I can find one) and plug in my chip, and then will it show my historical marks and mapping?
- If I buy one of the inland lakes models (cheaper and plenty available), if I plug in my other cards does that then add the coastal mapping? Or is that feature something built in to the unit’s hardware
- Lowrance Reveal models- could I get one of those in splitshot, use the existing transducers, and use the cards I have to add my marks etc?
- Anything else I should be thinking about?

I’ve had a hard time finding specific answers online. I made a trip to one of the big box stores yesterday, almost no one on the floor and the one guy didn’t know much about finders. I appreciate any advice tou guys can give me, and if you know of a shop or an online retailer with that model please share the link if you don’t mind. Thank you!
