I use the
Navionics platinum+ on
Raymarine chartplotters along with
INavx and TZ (time zero) on ipads. Navionics on an
iPad will also be fine. No issues using the platinum plus
charts especially when you consider the large area covered. I picked up the entire
Med for around $1200usd from a Spanish online vendor. Time Zero uses raster charts which don’t give much detail, you’d be much better off with Navionics IMHO.
