Bounty Hunter TK4 Tracker Underwater Metal Detector Review
Where to buy
$71
Buy now With an 8-inch waterproof search coil, Bounty Hunter TK4 underwater metal detector is a great tool for excavating metals including aluminum, gold, silver, iron, and steel.
It operates on two 9V alkaline batteries that enable the gadget to continue detecting treasures for prolonged periods of time. The detector’s knob control interface is simple to read, especially when taken into account the device’s 3 operation modes.
You can make use of the notch control to distinguish between the unwanted metals and valuable deposits, which will be easy to do thanks to the rugged construction of the metal detector.
Get rid of the undesirable objects with the built-in discrimination mode, maximize the detection depth with the integrated sensitivity control, and promptly switch between the modes with the toggle flick. No matter what your end goal is, you can successfully achieve it with this device.
Things we like:
- Supports 3 operating modes such as 2-tone audio mode, discrimination mode, and motion all-metal mode
- Is able to detect objects hidden 3-feet deep below the ground
Things we don't like:
- Not the most accurate metal detector on the market

DIVEIN's take
Why buy from Amazon?
Amazon has a documented Prime delivery program that covers millions of items, and that is the most concrete order-related support behind buying here.
Worth knowing
Some customers report slower replies or needing more follow-up than expected when they asked for help after ordering. If an order needs post-purchase support, that part of the experience is not always smooth.
Some customers also report delivery problems after ordering. That keeps follow-up and delivery as the areas to watch if you place the order here.
