The Gbnryg M55Z is the fifth entry in our guide to the best metal detectors. It is a £109.99 detector sold under the title "Professional Metal Detector for Adults", with five detection modes, an IP68 search coil, a backlit LCD and a kit that the bullets say includes a large capacity backpack, over-ear headphones with adjustable volume and a manganese steel digger. The listing shows 4.4 out of 5 from 1,535 ratings and a best sellers rank of 6 in Metal Detectors.

The reason it sits at number five is the batteries. Three fields on the same page disagree with each other: "Are Batteries Required" is answered "No", "Power Source" is listed as "Battery Powered" with a battery type of 9V, and the third bullet says two batteries are included free in the box. A detector cannot both not need batteries and ship with two of them. Where a number usually slips, this one holds: the search coil size is given as 30.48 Centimetres, which is 12 inches, matching the 12-inch coil named in the item highlight. Everything on this page comes from the Amazon listing as it stands; we have not tested the Gbnryg M55Z ourselves.
