Scrolling in works better. ### 1/5 — Still trouble with easyTRX3 transponder *2024-07-02* Position is lost often, even though GPS signal is definitely OK! That‘s absolutely inacceptable. Support doesn‘t respond to this serious problem at all! ### 5/5 — Great and Getting Better *2021-07-16* I’ve been following SeaPilot from their beginnings and their connection to Raymarine my primary chart plotters and VHF, I gave it a try. The coastal charts around Florida are enough to get around on, the AIS responds quickly. Each update improves it even more. Diehard fan and hope to continue to see more growth and integration in the app. Awesome stuff thus far, looking forward to even more. ### 5/5 — Nichts für Schlauchbootkapitäne! *2020-11-07* Aber für dieses Geld bekommt man ein Spitzenprodukt, welches Schäden durch Grundberührungen sicher verhindert. Es macht das bisher eingesetzte Garmin überflüssig. Auf dem Handy habe ich erst nur getestet, nun auf dem iPad ist es für meine Bedürnisse optimal. Der Export der GPX-Files verlief in plug&play, alle alten Daten / Tracks und Wegpunkte sind weiter verfügbar. ### 1/5 — Canada East *2020-07-31* Please do not throw away your money! The maps are horrible and does not show many of the rocks. Best App for Eastern Canada is Navionics! I am requesting my money back!! ### 1/5 — Useless *2020-07-19* Downloaded the app and paid £17.00 for a chart. Unable to load or activate chart. Useless. Don’t waste your time and money. Update: I have now managed to activate the chart. It does not scale in and out well with far too much detail (e.g. soundings) completely cluttering the chart when zoomed out. (You can turn off deep water soundings but this does not solve the problem). As far as I can tell, you need to upgrade to ‘Premium’ if you want to access any significant functionality (e.g. even the basic features of any navigation software such as plotting routes). There does not appear to be any weather and tide data available beyond the ‘tidal diamond’ in-out information found on paper charts. I was really hoping for something better than the ‘other’ marine navigation app which frustrating as it is, remains far ahead of the free version of this. Update to update. I really want this to work as the other app which could be so good is so awful in places. Careful checking of the Seapilot website does say that additional features are available in the premium version. I’d be more inclined to pay if there was a free trial period. I’m a bit reluctant to put £40 down only to find that it’s not what I want. ### 5/5 — App has worked great for me. *2020-05-24* Downloaded this app on my IPhone to have a backup. I like having redundant systems. Well today my Raymarine chart plotter took a dump. The Seapilot app helped me navigate flawlessly. ### 4/5 — Very nice app with one thing missing *2019-08-29* Vesper AIS support would be wonderful. ## Frequently asked questions about Seapilot ### What is Seapilot's rating and how many reviews does it have?
