What this assumes
- Products must be listed for your goal by their maker's features. That's my judgement from their published specs, not a test.
- GPS battery is the maker's standard GPS figure, not a measured one. Real use usually falls short, and it depends on settings, music and maps.
- A battery minimum rules out any product with no published figure.
- With a budget set, a product with no verified price can't count as fitting. It appears on its own line under the picks.
- Prices are UK prices read on the store named, on the date on each product page. They change.
- Among equal matches the lower price goes first. No store pays for a place, and a commission doesn't change the order.
