When you think about metal detecting, an image of walking along the beach searching for treasures might be the first thing that pops into your mind. But if you are considering purchasing a metal detector for the beach, there are actually special features you should be looking for as you select the best salt water metal detector that’s most suited for your very specific needs.

Challenges of Metal Detecting at a Salt Water Beach

Using a metal detector along the ocean sounds like so much fun, but you need to know that the salt water and “hot rocks” you find there can seriously mess with your signal. The salt water magnifies ground minerals that normally would not affect the signal you receive. If you are using a typical land metal detector, you could get tons of false signals.

Imagine how frustrating it would be to start digging for your object, only to discover there isn’t anything there. If that happens a few times, you will be ready to pack it in and never search the beach again.

Luckily, choosing a Very Low Frequency (VLF) metal detector that has a ground adjust control will allow you to set your detector so it does not send you false signals. When you purchase a metal detector, it should arrive with a preset ground adjust. This is great if you plan to search your backyard or the park down the street, but for the beach, you will not be happy with its performance. You can find VLF metal detectors for a very reasonable price.

Another option is available if you want to spend a little more money. Pulse Induction metal detectors are programmed to ignore any effects ground minerals send. You won’t have to worry about making any adjustments. You can just pick up your detector and head to the beach.

How Deep Will You Search?

Another consideration in choosing the best metal detector for the beach is how deep you plan on going into the water. Most metal detectors that are used for salt water have a waterproof coil when you purchase it.   If you plan on staying in water that is only a few inches deep, any of these will be fine.

If you would like to search in water up to around ten feet deep, you need to purchase one that is completely water proof. Even these detectors are not made for diving or deep snorkeling. If that is your plan, you need to select a metal detector that has been pressurized.

Now that you are ready to choose a metal detector for the beach, we have several options for you to check out. If you don’t want to spend a lot of money until you see how much you enjoy hunting, the Garrett Ace 350 or the Bounty Hunter Platinum would be good choices.

The Garrett Ace 350 has a price of around $300. It cannot be used in water of more than a few inches, but the coil is completely waterproof. This detector is excellent for use in highly mineralized areas and the coil is large enough that you can easily find your targets. The coil is narrow and long so it’s simple to pinpoint the location of your treasure. Other features include:

  • Easy touch push button controls
  • Reject and accept discrimination
  • Enhanced iron resolution
  • Electronic pinpointing
  • 6 search modes
  • Depth indicator
  • Two year warranty

The Ace 350 was designed for comfort and is one you will truly enjoy using for hours at a time.

  • Bounty Hunter Platinum

The Bounty Hunter Platinum costs about the same as the Ace 350 – around $300. It also has a ground balance adjustment, so you can easily use it at the beach or anywhere else. This model is very lightweight and is so simple a beginner can take it from the box and start searching their backyard immediately.

  • Huge display

The best thing about the Bounty Hunter Platinum is not only is it a great detector for the beach, but it does an awesome job everywhere else, too. Deep coins are no problem and you can also search for jewelry and relics.
