NATIONAL GEOGRAPHIC Underwater Metal Detector Review
Where to buy

$169.99
In case you always dreamed of becoming a treasure hunter but never had the funds to make it a reality, take a close look at the underwater metal detector released by National Geographic. This easy-to-use tool comes in 2 styles – junior and professional – and is an optimal variant for every scuba diver out there.
It has got a 10-inch search coil that is fully waterproof and thus submergible under the water.
The 3 detection modes built into the device allow you to easily filter out garbage and find the exact metals you are looking for. To foster successful hunting, the manufacturer further incorporated 4 sensitivity modes that enable you to detect underground treasures buried as deep as 12 inches beneath the surface.
The data appearing on the LCD display is quite easy to decipher, which gives you the opportunity to make the most out of your searching experience.
Things we like:
- The 3 detection modes allow you to search for iron, aluminum, coins, and precious jewelry
- The lightweight design means that you can bring your detector with you on a faraway destination as it will easily fit into your backpack
Things we don't like:
- Doesn’t have any unique features

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.
