Beginner detector guide · checked August 28, 2026
There is no magic machine for every place. Pick the detector that matches your ground, the water you may enter, and the controls you want to learn.
The quick answer
All three weigh 2.6–2.8 pounds. Comfort still depends on your height and fit. The big differences are water protection, detecting technology, and control.
Simple first detector
Beginners who want the whole detector—not just the coil—to go underwater.
Coins and mixed ground
A simple turn-on-and-go detector with simultaneous multi-frequency technology.
Familiar controls
Dry-land hunters who want clear U.S.-coin target IDs and discrimination—the control that ignores unwanted metals.
Side-by-side
“Waterproof coil” and “waterproof detector” are not the same. This table keeps that difference visible.

The full shortlist
We match the model and included package to the Amazon page, so a look-alike version does not sneak into the comparison.
Simple first detector
Beginners who want the whole detector—not just the coil—to go underwater.
The full detector is submersible, it weighs 2.6 pounds, and four simple modes cover common first-hunt ground.
This checked package uses the smaller SX24 coil. Do not confuse it with the separate SX28 package.
Coins and mixed ground
A simple turn-on-and-go detector with simultaneous multi-frequency technology.
Multi-IQ listens on several frequencies at once, while three search modes keep the first setup simple.
The coil can enter water, but the control box cannot. This is the 340—not the newer fully waterproof VANQUISH 360.
Familiar controls
Dry-land hunters who want clear U.S.-coin target IDs and discrimination—the control that ignores unwanted metals.
Five search modes, a numeric target ID, and adjustable discrimination make dry-ground signal learning easy to follow.
The coil can enter water, but the control box must stay dry. This is the U.S. ACE 300—not the international 300i.
Five-minute decision
Do this before watching another depth test. Your real ground matters more than one perfect video target.
Dry parks, freshwater edges, or a salt beach?
If yes, choose a fully waterproof detector—not only a waterproof coil.
Simple gets you swinging faster. Extra controls give you more ways to learn.
Comfort beats a feature you stop using after twenty minutes.
Leave room for headphones, a recovery tool, a pouch, and maybe a pinpointer.
Useful add-on—not a detector replacement
The main detector finds the signal. The Garrett PRO-Pointer AT then helps you locate the target inside the plug—the small piece of soil lifted from a hole—or sand scoop.
How we chose
Buyer FAQ
Choose by ground. The Nokta SIMPLEX LITE is the easiest pick when full waterproofing matters. The Minelab VANQUISH 340 is the simple multi-frequency pick. The Garrett ACE 300 suits dry-land beginners who want familiar coin IDs and more discrimination control.
Only if the control box may get wet or go underwater. A waterproof coil does not make the whole detector waterproof. Check the control box separately.
A pinpointer is not required, but it can make recovery faster and help you cut a smaller plug. It finds the target after the main detector has already found the signal.
