Considerations & Trade-offs
- The 18.5" Full-HD touchscreen is substantial, so it may be more display than needed for smaller consoles or simpler setups.
- Advanced networking and One-Boat Network integration add capability, but they also make the unit most useful when paired with compatible accessories and systems.
- Included LakeMaster and CoastMaster VX Maps cover over 13,000 lakes, waterways, and coastal waters in the U.S. and Canada, so map value is strongest within those regions.
- The feature set is extensive, which can mean a steeper learning curve for anglers who only need basic chartplotting and sonar functions.
