Quest Scuba Tector Pro Underwater Metal Detector

The Quest Scuba Tector Pro is a pulse induction underwater metal detector rated to 60 m (197 ft), with a search head that folds on a 180 degree hinge, an OLED display, sound and vibration alerts, and Snorkel and Dive modes. The included rod adaptor lets you run it on a shaft at the beach, and the optional STP20 round coil widens each sweep. It suits scuba divers, snorkelers and surf hunters. Our Scuba Tector collection holds the Scuba Tector Pro with its standard narrow head or with the 8 inch STP20 round coil, the STP20 coil, the Rod Extension Kit, O-rings and the quick start guide.

Quest Scuba Tector Pro Overview

The Quest Scuba Tector Pro is a handheld pulse induction (PI) metal detector built to be used underwater. It runs a salt-stable PI circuit, and its sealed housing is rated to 60 m (197 ft). The search head folds on a 180 degree hinge so the detector packs into a dive bag, an OLED display shows battery, mode and sensitivity status, and targets are signaled by sound, vibration, or both. Snorkel mode is for water shallower than 10 m (33 ft) and Dive mode for deeper water. The built-in Li-Po battery runs 10 to 14 hours per charge; the standard Pro comes with a USB-C charging cable, and the Pro with the STP20 coil comes with a magnetic charging cable. The box includes an anchor ring for handheld diving, a rod adaptor for a beach setup, spare O-rings, mounting hardware, a lanyard and a mesh carry pouch.

We list the Scuba Tector Pro in two ways: with the standard narrow open-face head for tight spaces, or with the 8 inch (20 cm) STP20 round coil for wider scanning.

Scuba Tector Pro vs the Original Scuba Tector: Which Should You Buy?

Both are pulse induction detectors for divers. The original Scuba Tector, which we sell as the XPointer Scuba Tector in our Quest pinpointers, is a one-hand probe rated to 60 m (197 ft), with a Snorkeling mode for 0 to 10 m (33 ft), a Dive mode for 10 to 60 m (33 to 197 ft) and beep, vibration or combined alarms. The Scuba Tector Pro has the same 60 m rating and adds a larger, folding search head, the OLED display and the option to mount it on a shaft.

If you recover known drops or want an underwater pinpointer to work beside a larger detector, the original Scuba Tector is enough. If you want to search open bottom on a dive or snorkel, or split time between diving and the beach, we recommend the Scuba Tector Pro.

Quest Scuba Tector Pro, Best For:

  • Searching open bottom on a dive or snorkel, with the STP20 round coil for wider sweeps
  • Divers who also hunt the beach, using the rod adaptor or the Rod Extension Kit
  • Low visibility water, where vibration alerts back up the buzzer

Original Quest Scuba Tector, Best For:

  • Recovering a known drop or pinpointing for a larger detector
  • The smallest, simplest probe to clip to a dive rig

Key Features That Matter in the Water

Pulse induction is the reason to choose a Scuba Tector for saltwater: a PI circuit is far less affected by salt water and black sand than a VLF circuit, so it runs quieter where many VLF detectors chatter. The two search heads change how you hunt. We recommend the narrow head for working between rocks, around pilings and in crevices, and the STP20 round coil for sweeping sand and silt in a swim area. A mode button sets the alarm type and sensitivity, and Snorkel or Dive mode matches the detector to the depth. Vibration matters most at depth and in murky water, where the buzzer is hard to hear. We recommend clipping the detector to your rig with the anchor ring and lanyard on every dive.

Where the Scuba Tector Pro Works Best and Its Limits

The Scuba Tector Pro is at home on recreational dives, on snorkel hunts, around docks and swim areas and on the beach with the rod adaptor. It is a handheld detector, so even on a shaft it covers less ground per swing than a full-size detector. Depth rating is how deep the housing is sealed for, not how deep it senses a target. For a full-length detector for wading and wet sand, start in our underwater and waterproof metal detectors, compare other PI machines in our pulse induction metal detectors, or add a scoop from our sand scoops and diving tools.

Coils, Rod Kit and Parts That Fit the Scuba Tector Pro

The Quest STP20 waterproof search coil is an 8 inch (20 cm) round coil with its own handle: the Pro's electronics module moves into it, so it fits the Scuba Tector Pro only. The Quest Scuba Tector Pro Rod Extension Kit adds a two-piece shaft, a handle, an armrest with strap and coil hardware, and works with either search head. The Quest Scuba Tector O-ring replacement is the battery cap seal for the original Scuba Tector; whichever model you dive, we recommend checking its O-rings before every dive. The Scuba Tector Pro quick start guide is a free download, and our guide on how to change the Scuba Tector Pro coil walks through the STP20 swap.

Quest Scuba Tector Comparison: Original vs Pro

Both are pulse induction detectors made for diving. Both are rated to 60 m; the differences are search head, display and how far each can be reconfigured.

Can the Quest Scuba Tector Pro be used standing up on the beach?

Yes, the Quest Scuba Tector Pro can be used standing up on the beach. The box includes a rod adaptor for a beach and shore setup alongside the anchor ring used for handheld diving, and the Quest Scuba Tector Pro Rod Extension Kit adds a two-piece shaft, a handle and an armrest with strap. The kit works with the standard head or the STP20 coil.

Which detectors does the Quest STP20 search coil fit?

The Quest STP20 search coil fits the Scuba Tector Pro only. It is an 8 inch (20 cm) round coil with its own handle, and the Pro's electronics module moves into it. It does not fit the original Scuba Tector, which is a one-piece probe. Our guide on how to change the Scuba Tector Pro coil walks through the swap.

Answered by Richard T. · October 2026

Is the Quest Scuba Tector Pro a pinpointer or a metal detector?

The Quest Scuba Tector Pro is a handheld underwater metal detector that can also pinpoint. Its folding open-face search head, or the 8 inch STP20 round coil, sweeps more bottom than a probe tip, and on the rod adaptor or the Rod Extension Kit it runs as a compact beach detector. For a small probe that only pinpoints, the original Scuba Tector is in our Quest pinpointers.

Answered by John W. · October 2026

How deep can the Quest Scuba Tector Pro go?

The Quest Scuba Tector Pro can go to 60 m (197 ft), which is the depth Quest rates its sealed housing for. Use Snorkel mode in water shallower than 10 m (33 ft) and Dive mode below that. The rating is how deep you can take the detector, not how deep it senses a target, and not how deep it is safe for you to dive; stay within your training. Our Quest Scuba Tector Pro review covers the dive modes in detail.

Answered by Dan P. · October 2026

Does the Quest Scuba Tector Pro have a lost alarm?

Yes, the Quest Scuba Tector Pro has a loss alert that helps the detector come home from every dive, and low-battery feedback on the body. We still recommend clipping it to your rig with the included anchor ring and lanyard on every dive. The Scuba Tector Pro quick start guide is a free download.

Answered by Richard T. · October 2026

How do you charge the Quest Scuba Tector Pro?

You charge the Quest Scuba Tector Pro's built-in Li-Po battery, which runs 10 to 14 hours per charge, with the cable in its box. The standard Scuba Tector Pro comes with a USB-C charging cable, and the Scuba Tector Pro with the STP20 coil comes with a magnetic charging cable. We recommend a full charge before every dive.
