Fish-finder screen planner
Anglers matching screen size to boat or kayak. The decision this page isolates is narrow on purpose: translate boat type into a sonar class. Capacity, season, and packed size are the published facts that survive a weekend trip.
This page produces an explainable category or size so options can be compared without a product ranking. The calculator does not rank Garmin, Humminbird, and Lowrance. It produces an explainable class so Garmin Striker 4, Humminbird HELIX 7, and Lowrance HOOK Reveal 7 can be compared as examples of that class.
The working method is: Convert the inputs into a published planning class using the method on this page, then compare official product pages that match that class. Planning notes are grounded in Osprey. This page does not quote a price or rank a brand.
