The Best Underwater Metal Detectors | Buyer’s Guide
The difference between an ordinary metal detector and an underwater metal detector is that it comes with additional features. This will enable you to target your specific metals on both water and land. Below are some of the features to help you find a model that meets your needs.
- Coil size: A large search coil has high accuracy and precision. As such, getting a model with a large search coil will improve your chances of finding the underwater treasure. This will play a major role in helping you find more treasures in less time. We recommend going for a model with a search coil of not less than 7 inches wide.
- The metal detector type: Underwater metal detectors come in two types. First, we have models that work with PI (pulse induction) detection. Secondly, we have models that work with VLF (very low frequency) detection. The Models that use PI detections are generally better since they work well in salt water and highly mineralized ground. However, if you are looking for a model to use in freshwater, the VLF models are a better alternative as they are cheaper.
- Water depth: As you can tell from the models that we have, these models come with varying water depth. We have a model that is submersible for up to 3 meters while others work well in depths of up to 15 meters. If you are planning for scuba diving, the latter is a great choice. However, if you need a model to help you find treasures in rivers or beaches the former makes an excellent choice.
From beachcombing to scuba diving, the best underwater metal detectors will assist you in finding the hidden treasure. Our detailed guide includes the best models that boast of advanced and modern features that ensure a better user experience. Better still, these models also work well on dry land. This makes them an excellent choice for anyone looking to get into this hobby as well as advanced hobbyists. All the best!
