The short answer
Buy the Minelab Equinox 900 package with 11-inch and 6-inch coils if you want one premium detector for parks, fields, beaches and occasional gold work without assembling a modular system.
Buy the XP DEUS II package with the 9-inch FMF coil, remote and WS6 headphones if low weight, extensive audio/program control and deeper-water capability justify a more involved ownership setup.
The expensive mistake is choosing by reputation alone. These detectors solve the same broad problem in different ways: the Equinox 900 is a complete conventional package; DEUS II is a configurable wireless platform.

Why the Equinox 900 is the safer default
Minelab’s package is unusually easy to understand. The current Equinox 900 includes the EQX11 general-purpose coil, the EQX06 coil for tighter or trashier ground, ML85 wireless headphones, the carbon-fiber shaft and the charging hardware. You do not have to decide which control module or search coil makes the product complete.
That second coil changes the value calculation. A small coil is not a universal depth upgrade; it gives up ground coverage. Its value is separation and maneuverability around iron, roots, playground equipment and dense modern trash. Buyers who would add a small coil later should count it as part of the package, not as a free extra with no use.
The 900 also keeps its controls in a familiar format. Its four search-mode families cover Park, Field, Beach and Gold, each with two profiles. It offers a 119-segment target-ID range, recovery-speed settings from 1 to 8, iron-bias adjustment and six single-frequency choices alongside Multi-IQ. There is plenty to learn, but the machine still behaves like one detector rather than a network of paired components.
Choose it when:
- your week can include turf, fields and saltwater beaches;
- you want the 6-inch coil without another purchase;
- you prefer one control pod and one main charging routine;
- you want target vibration, a red backlight and a built-in flashlight;
- you value a ready package more than shaving every possible ounce.
Why an experienced buyer may prefer DEUS II
XP’s advantage begins with weight. The company lists configurations starting at 750 grams, and the remote can be mounted on the stem or carried separately. That matters over a long hunt or for anyone whose wrist, elbow or shoulder limits comfortable swing time.
The second advantage is configuration depth. DEUS II provides 12 factory programs, 12 user slots, extensive audio options, reactivity controls, ground handling and FMF operation. The coil, remote and headphones communicate through XP’s proprietary wireless system. A buyer who understands how those pieces fit together gets a detector that can be tailored closely to site and listening preference.
That modularity is also the ownership trade-off. The remote, coil and headphones have separate batteries and published runtimes. XP lists up to 25 hours for the remote, up to 17 hours for headphones and up to 20 hours for the coil, depending on program and frequency. Charge planning and pairing are part of the product.
Choose DEUS II when:
- low system weight materially increases how long you can hunt;
- you will use its audio, program and reactivity controls rather than leave everything near default;
- you want a platform with multiple coil and headphone configurations;
- 20-meter waterproof capability is relevant to your actual hunting;
- a five-year manufacturer warranty matters more than a two-coil starter package.
Water use is not a one-number comparison
The DEUS II has the deeper rating: its coils and supported water setup are IP68 rated to 20 meters. But radio does not travel normally through water, so XP supplies an antenna that must connect the submerged coil’s signal to the control system. Buyers planning to dive should learn that setup before the first trip.
The Equinox 900 is IP68 rated to 5 meters. That is enough for rain, surf, rivers, wading and many shallow-water hunts, but it is not a 20-meter dive detector. Minelab also specifies waterproof EQUINOX headphones for full submersion; the included ML85 wireless headphones are not the underwater audio answer.
For ordinary beach use, choose based on the whole detector, not the deeper number. For actual diving below 5 meters, the DEUS II is the only one of these two with the required published rating.
Package identity matters before checkout
DEUS II listings can refer to a full remote package, an RC-only configuration, or a WS6 Master configuration, with different coils and headphones. The exact Amazon product linked here names the 9-inch FMF coil, remote control, WS6 headphones and S-Telescopic stem. Confirm those components on the offer you select.
The linked Equinox 900 product is Minelab model 3720-0006 and names both the 11-inch and 6-inch coils. If a cheaper offer omits the smaller coil or substitutes a dealer bundle, it is not the same package even if the detector body is identical.
What each buyer should skip
Skip the Equinox 900 if its 2.8-pound weight is already near your comfort limit, you want a highly modular wireless system, or you genuinely need more than 5 meters of water protection.
Skip DEUS II if you dislike managing multiple charged components, you want two useful coils immediately, or you are unlikely to use its deeper programming. Paying for configurability while avoiding it is poor value.
If Minelab is already your preferred control language, also compare the Manticore and Equinox 900 . If the choice is mainly whether a current 800 owner should upgrade, use the Equinox 800 vs 900 comparison instead.
Verdict
The Equinox 900 is the better purchase for most mixed-site detectorists because its two-coil package is complete, its control architecture is conventional, and its published specifications cover a broad range of land and shallow-water work.
The XP DEUS II is the better specialist platform for buyers who will exploit its low weight, modular wireless hardware, deeper waterproof rating and extensive configuration. Those are real advantages, but they are not free value for someone who wants a simpler detector.

Frequently asked questions
Which is easier to buy as a complete package?
The Equinox 900 is clearer: Minelab includes both its 11-inch and 6-inch coils plus ML85 wireless headphones. DEUS II bundles vary, so compare the coil, remote and headphone configuration line by line.
Which detector is lighter?
XP lists DEUS II configurations starting at 750 grams, while Minelab lists the Equinox 900 at 1.27 kilograms. The exact DEUS II weight depends on whether the remote stays on the stem or in a pocket.
Which is better for underwater detecting?
DEUS II has the deeper published rating at 20 meters, but submerged use requires XP’s antenna between the coil and control system. The Equinox 900 is rated to 5 meters and is simpler for beaches, wading and shallower water.
Is the DEUS II automatically better for difficult sites?
No. Its low weight and extensive program, audio and reactivity controls appeal to experienced users, but those advantages matter only when you will tune and use them. The Equinox 900 is the stronger default when a complete package and quicker setup matter more.
