Tips for Choosing the Perfect Underwater Metal Detector

There are very few things as fun and exciting as using an underwater metal detector to search the water and sand for treasure. Many people enjoy taking their detectors to the rivers, lakes, and oceans after the summer so find the little tidbits that tourists have left behind. If that sounds like something you want to be a part of, the first thing you need to do is be sure you have an underwater metal detector that can stand up to the job.

If you already have a metal detector, you might think you’re ready to go but there are some things you should know. Underwater metal detecting requires specialized equipment. Before you jump into the ocean, it’s important to be sure your detector is waterproof. Those who are going to search at the sea rather than in a lake or river will also want to be sure the detector can stand up to the saltwater conditions.

We’re going to offer some input on what to consider when choosing the right waterproof metal detector for your needs.

Choosing Between Very Low Frequency and Pulse Induction

There are two distinct types of underwater metal detectors that work well in salty underwater conditions: Very low frequency (VLF) and pulse induction (PI).

A pulse induction detector uses frequent bursts of electronic pulses that go into the ground. A signal comes back to the detector if something metal is found by one of these pulses. This is the optimal choice for saltwater conditions since they can handle large amounts of mineralization. However, they aren’t quite as good as determining what is metal and what is junk as the VLF detectors can.

There are PI detectors that are better at distinguishing between items, but they tend to cost quite a lot.

Very low frequency metal detectors use a low frequency to detect metals and the technology associated with them makes them better at distinguishing between treasure and trash. A decent VLF will pass over mineralized soil so you can find what you want without ending up digging for nothing but a tin can.

Determining which machine is better for your needs can be tricky. The reality is that a VLF is going to be more versatile. These machines can be used on land, in freshwater, and in saltwater and have a good chance of only picking up the things you’re after. These machines also tend to be lighter so carrying them around isn’t stressful.

However, PI detectors are often capable of finding smaller and deeper items and are programmed to avoid ground minerals. There’s no adjustment needed, you can just take the detector and get going.

Those who plan to do most of their hunting in the water or near the ocean may be better off with a PI detector. Those who will be spending time on land or near freshwater more often might be best off with VLF waterproof metal detectors.

Making Sure Your Metal Detector is Waterproof

Some metal detectors are entirely waterproof while others may have a waterproof coil and still others are only water resistant. Make sure you understand what sort of detector you are buying before you put down the cash.

If you’re going far into the water, you want a fully waterproof model. If you’re only going to be dipping into the shallow, a coil model with a control box that isn’t waterproof may be reasonable. Those who want a weatherproof model but won’t delve into the water may be fine using a water-resistant detector.

When to Go Underwater Metal Detecting

If you enjoy scuba diving, there’s nothing to say you can’t add metal detecting to your agenda any time of the year. However, those who want to choose the optimal time of year will find that there’s nothing better than detecting during the warm summer months.

This is when all sorts of beachgoers and tourists are heading into the water and likely losing some jewelry in the process.

In addition, the summer is warmer than winter in most places so you can spend more time detecting before you need a break. However, metal detecting in winter is possible if you watch the weather and bring along a wetsuit. Avoid heading out into the water if it’s stormy.

As far as the time of day goes, the best time to metal detect is during daylight hours. It’s a safer time of day and you can see what you are doing better.

Considering the Tides

If you are going to be jumping into the water, it’s important to be aware of where the tide is and where it is going. This is something you may already be familiar with if you spend a lot of time on the beach. It’s just as important when metal detecting. You don’t want to end up caught and pulled out with the tide.

There are other things to know about the tide, as well. Being aware of where it is can help you find items underwater more easily and quickly. The sand moves in the direction of the tide, which lets you see a larger amount of the seabed. Avoid fighting the tide for the best results when in the water.

Accessories to Consider

There is no requirement for having extra accessories when using your submersible metal detector, but that doesn’t mean they can’t offer you advantages. While there are dozens of options out there, we wanted to talk about a few that bring the most bang to your metal detecting adventures.

Mesh Pouch

If you scuba dive or snorkel, you likely know the convenience of having a mesh pouch with you. This is the same case when you have a metal detector with you. While you are underwater exploring, you need somewhere to stash all the finds you come upon.

Waterproof Headphones

When you’re in the water, things can get pretty noisy. The sound of the waves can drown out the sounds of target signals. If you are planning to head under the water, having a pair of waterproof headphones that fit your water metal detector is something that will make life much easier.

Chest Harness

You may or may not need a chest harness, but it can be a huge help if you have a metal detector that is heavy. Even something that is only a few pounds can feel a lot heavier when you’re moving it side-to-side over the course of a few hours. It doesn’t help that the waves can pull the metal detector around.

A chest hardness can take the weight off of your arms and make exploring safer since you can easily keep your balance and steady yourself.

Long Trowel

Having a trowel will make a huge difference when digging treasures out of the sand. It will move sand much more quickly than digging with the hands. Those walking and snorkeling can remain standing while using a trowel to dig and uncover a target in the sand.

Getting Started with Metal Detecting Underwater

If you enjoy metal detecting, it’s likely you’ll eventually end up in the water if not far underneath the surface. Many people start out their hobby with a metal detector on the lakeside or the beach but end up delving into the water itself. There are tons of things to find and if you have the right equipment, you never know what you might turn up.

We recommend choosing a best waterproof metal detector from our list above or at least using it to guide your own search. Once you get in the water, it will be well worth having spent the time to find the best detector for your needs. Good luck and have fun out there!
