Bring you to a new world of treasure Scuba Tector Metal Detector features pulse induction (PI) technology and a 5x4” mono coil, allowing for high levels of sensitivity and penetration depth not found in other models. The Quest Scuba Tector also enables you to search underwater up to 200 feet (60 meters) with its submersible waterproof housing. The underwater design is great for finding underwater historical relics, rings, gold bracelets and more! Even with its subaquatic searching technological capabilities, the Scuba Tector remains functional and lightweight. The easy-to-hold body of the Scuba Tector offers hunters stability and comfort while detecting. Featuring a industry first "Dive Mode", users hold the two buttons for 2 seconds on the Scuba Tector for function while underwater. A red light will flash five times and vibration will begin. Quickly depress the Mode button 3 times  to switch back to shallow water hunting mode. If you are a detectorist that hunts both on dry land and underwater, the Quest Scuba Tector Metal Detector will be a great addition!
