Lorenz Deepmax Z1 Metal Detector Review
If you’re looking for the best pulse induction metal detector the Lorenz Deepmax Z1 is your top choice.
This pulse induction metal detector was created for professionals and has all the tech you could need.
The pulse ground balancing system (GBS) was specifically created for deep ground penetration making this one of the deepest seeking machines you’ll find.
The Deepmax Z1 is unaffected by salt water and highly mineralized grounds and it performs well near other detectorists or power sources with its new design circuitry.
The LC display gives target ID for all metals on a scale of 0-99. Gold will register high for example.
This is an excellent feature when paired with the ferrous indicator icon.
If the target reads as iron an FE indicator will appear. Other metals such as copper will ping up a NON-FE. This increases your chances of digging something worthwhile.
The Z1’s exact pinpointing is a real plus in moving saltwater conditions and you get a 14” DD search coil which is interchangeable with others in the Lorenz range. This large starter coil is perfect for deep seeking.
It has fast adjustable audio with different settings and top-class sensitivity that enables you to eliminate small objects or trash.
This is the best metal detector with pulse induction because it incorporates years of research in its tech yet it only takes three buttons to operate.

Aquascan Aquapulse AQ1B Diver Metal Detector Review
The Aquascan Aquapulse is a top-notch piece of kit and many consider it the best pulse induction metal detector for divers.
The Aquapulse is designed for deep diving and can withstand 100 meters of pressure. Professionals use this machine to recover wrecks and track underwater cables.
It’s perfect for diving but works well on the beach and on highly mineralized grounds too. If you’re gold-seeking on land or under the waves this is your perfect detector for sure.
The search coil is an 8 incher on a telescopic arm that has neutral buoyancy in water. It’ll scan metal buried three meters deep according to Aquascan and swaps out to fit Aquascan’s range of search coils that suit various underwater, muddy conditions.
The Aquapulse has sensitivity and threshold adjustments plus functions that reject ring pulls and other trash.
For example, the ‘REJECT’ control changes its sensitivity. At its lowest it will target small rings and foil and as it increases will resist signals from rings pulls or silver foils. This means you can set the Aquapulse to suit your preference.
The Aquascan Aquapulse is a top PI metal detector for divers with its rechargeable NiMH batteries (8-10 hours of use) and a sturdy telescopic arm.
If you’re going deep under water, this is the best pulse induction metal detector for you.

Garrett Sea Hunter Mark II Metal Detector Review
Garrett make great PI detectors and the Sea Hunter Mark II is their other top-of-the-range machine. It’s one of the best pulse induction metal detectors on the market.
The Sea Hunter Mark II has superior automatic salt elimination with 22 frequencies so it’s ideal for saltwater. If you find it chattering a little, use the easy discrimination settings to settle it down
This top-quality pulse induction detector has an all-metal deep-seeking mode and two discrimination modes. These are standard trash discrimination and discrete trash elimination to get the level of trash elimination you require.
The sensitivity and depth are fixed and the audio threshold can be adjusted to suit on a 0-10 scale.
This is another metal detector made for divers as it is submersible up to 65 feet including the headphones and has a one-handed operation control box.
The coil is a concentric 8-inch mono PROformance coil for deepseeking and it has a telescopic arm that will shorten to a diver-friendly 28 inches – perfect for horizontal searches.
Garrett’s Sea Hunter Mark II isn’t as powerful as the ATX Deepseeker, but it’s fully submersible and was favored by expert treasure diver Sir Robert Marx.
This is a great machine for the price and certainly one of the best pulse induction machines for salt water you’ll encounter.

Nokta Makro Pulsedive Scuba Metal Detector Review
Nokta are described as a rising star in the detector world and the Pulsedive Scuba metal detector is their best pulse induction metal detector for innovation and price.
Ths is a pulse induction two-in-one machine. It quickly transforms between a mini waterproof pulse induction metal detector and a waterproof pinpointer. The search coil can be swiftly swapped out for the pinpointer head using its quick fit bayonet fittings.
Top-class technology means the Pulsedive is very stable in salt water or on highly mineralized grounds. It has five levels of sensitivity to suit the conditions and a frequency shift option if you’re near other detectorists or a source of power.
The Pulsedive uses audio, vibration, audio plus vibration, or an LED indicator to highlight finds so you don’t need to use headphones – just look at the flashing (or not) LED.
That said it has a built-in wireless module for headphones should you want them and a diving mode that locks the keys against water pressure from deep dives.
This 28 cm little guy is waterproof to 60 meters and has a hard coil cover for its 5.5-inch coil (plus one for the pinpointer). It’s certainly rugged and small enough to push between rocks and weeds for fallen treasure.
The Pulsedive uses a 1650mAh Lithium polymer battery that takes two hours to charge and lasts the whole day. It’s perfect for diving, snorkeling, or rock pooling with its handy size and two-in-one pulse induction functions.
What To Look For in The Best Pulse Induction Metal Detector
Pulse induction metal detectors are best used in salt water, wet sand, and highly mineralized ground because they ignore the mineralization but maintain high sensitivity.
Here’s what to look for in the best metal detector with pulse induction.
If you’re planning on detecting in the water of any kind, waterproofing is important. A waterproof coil or a submersible PI detector is necessary.
PI metal detectors are ideal for wreck diving, but check its depth capacity out first. Water pressure can do Very Bad Things to circuitry and PI machines are not cheap.
Pulse induction metal detectors are immune to salt water and highly mineralized grounds, but sometimes they need an adjustment. This is when good discrimination is your friend.
Sensitivity or Iron Check
Iron check is a handy feature but not all pulse induction metal detectors have it. (The Deepmax Z1 does as does the Garrett ATX).
Because PI machines don’t generally use modes having something to filter unwanted targets or trash is useful. Adjustable sensitivity is a proven way to filter out ferrous targets and unwanted metals.
Continuous Ground Balance Check
This is a feature only found on the best metal detectors with pulse induction electronics. A continuous ground balance check that readjusts itself accordingly isn’t essential but makes life easier when you’re striding between the ocean and dry sand.
The best coil size depends on your intended use.
If you’re a wreck diver, snorkeller, or a surf detectorist then a small coil such as the 8 inches on Garrett’s Sea Hunter, or the 5.5 inches on the Pulsedive, is lightweight and easy to fit into small spaces between rocks.
That said, a large coil such as Lorenz’s 14-inch DD covers more ground which is handy if you’re striding out in the gold fields.
Look for options to swap out coils.
Pulse induction metal detectors are not cheap so its worth doing your research.
The best pulse induction metal detectors listed above are all worthy of your money. They won’t let you down or embarrass you, and each has a band of followers.
Choose the best PI metal detector you can afford and practice until you have it down pat. There’s no other way to maximize your finds.
