Inch: The GreenRex REX8-Ultral is a metal detector with five listed detection modes, an LCD, an adjustable shaft, and a waterproof search coil. Its listing describes beach and shallow-water use, but says the control box is not waterproof, so it is not presented as a fully submersible detector.

## Before you buy

- The listing presents 10 inches as the coil size and separately claims detection up to 7 inches deep. The control box is not waterproof, so do not submerge the complete detector. Battery type and runtime are not specified. The listed 11"L x 6"W x 24"H dimensions are not explained as assembled or packed dimensions, while the feature text separately gives extended and compressed lengths. The stated 5-pound weight is listing information, not an independently measured figure.

## A good fit for

- Beginners looking for a detector with several selectable modes and a backlit LCD.
- Beach or shallow-water searches where the coil can enter water while the control box remains dry.
- Families or travelers who want an adjustable shaft that compresses for packing.

## Less suited to

- Underwater searches that require submerging the control box or entire detector.
- Buyers who need stated battery runtime, battery type or independently established depth performance.

## Customer feedback

Customer feedback highlights perceived accuracy, easy assembly, clear instructions and beginner suitability. Some customers describe the detector as comfortable to swing and enjoyable for family treasure hunts. Those impressions fit the listed adjustable shaft and five modes, but do not establish measured detection accuracy or performance. The aggregate ratings skew strongly positive, while a smaller share of lower ratings means experiences are not uniformly favorable.
