What to know before buying

Listing details to confirm

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.

Who is it for?

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.
