The Navionics app works well, but I think most people would still have detailed maps on their fish finder unit. May cost extra with some models, but well worth it. If budget is the issue, then the Navionics app is a good solution.

Have you got the right settings on in your Lowrance? Normally you have to tell it where to source the charts from and which layers you want on, high res bathy, reveal etc. It's very likely that the Lowrance is still using the standard charts not the reveal card.

This is the map select options . The navonics is mega basic , the lowrance is way better but I was told the c-map reveal was the best....but the sales guff did say the reveal was pre-installed and I think this is the lowrance on the menu selection , but near as I can tell its the same as the c-map card I paid nearly 300 duckin follars for.
Anyhow , can I put this card in my phone ( it looks like it will fit ).
And , I bought the card wanting the fantastic bathymetrics it boasted.......but not, as I thought, the whole of NZ .....certainly not Riverton .
😁Ya know ya sit in the boat , looking at the screen wondering wtf all the icons mean , wife says "#uck this , just chuck a line in , we'll soon know if they're fish "😆
