Review on 🌊 Navionics Platinum+ MSD/638P+ Puget Sound Nautical Chart - SD/Micro-SD Card by Daniel Jackson

I purchased a platinum chip to use the auto trace feature in a device that came with regular Navionics charts. The Platinum setting messes up the normal fringe charts. This is because the Platinum maps end at the Canadian border, but the overlay is rectangular, so you lose all adjacent map information between the border and the edge of the rectangular field used by the Platinum map (see attached screenshot) . support solution? Put your original Navionics chip back in the plotter! As for autorouting, sometimes it's very hard to stop it from what it thinks is the best course. Just try to cruise up the Snomish Channel a bit - this will send your boat through Deception Pass. Verdict: Master manual routing with basic Navionics software (which is good). Don't waste your money on Platinum.
