Nokta Simplex Lite vs Simplex Ultra: What $50 Actually Buys You
Quick answer
The Simplex Lite at $249.00 has a 9.5 inch waterproof DD coil and vibration alerts. The Simplex Ultra at $299.00 publishes full waterproofing to 16 feet, a carbon fibre shaft and an 11 inch coil. Nokta does not publish a submersion depth for the Lite in this listing, which is the biggest gap between the two.

Check price on AmazonFifty dollars separates these two Noktas, and the published record is not symmetrical between them. Nokta Simplex Lite is documented in our catalog with a 9.5 inch waterproof DD coil and vibration alerts, aimed at hard-of-hearing users and anyone who wants a lighter build, for $249.00. Nokta Simplex Ultra publishes considerably more: full waterproofing to 16 feet, a carbon fibre shaft that retracts to 25 inches, an 11 inch coil, online firmware updates and a 2.6 lb weight, for $299.00.
That is not necessarily a smaller machine, it is a less fully documented one in this particular listing. Nokta does sell the Simplex line as a family with shared waterproof design language, but this page can only state what is actually published for each model, and the Lite's listing here does not carry a submersion figure the way the Ultra's does. The Nokta waterproof depth ratings page is where to check the current manual figure before buying either one for wet ground.

Nokta Simplex Ultra
Full waterproofing to 16 feet, a carbon fibre shaft, an 11 inch coil and online firmware updates, all clearly documented in the current listing.

Why is the gap in the published record itself the story here?
Because it changes how confidently you can buy the Lite for a specific job. The Simplex Ultra's listing states a submersion depth, a shaft material, a weight and a firmware update method, all facts you can check against the current manual before buying. The Simplex Lite's listing in this catalog gives a coil size, a coil type and the presence of vibration alerts, and stops there. That is a gap in this particular record, not proof the Lite lacks waterproofing or a light build, but this page will not print a number it cannot source.
What we can say with confidence is the coil size difference: 9.5 inches on the Lite against 11 inches on the Ultra, which is a real, if modest, difference in ground coverage per sweep. The coil size versus depth chart explains what an inch and a half of coil diameter typically costs you in coverage and gains you in manoeuvrability.
How do the published specifications compare?
The Lite's listing is thinner than the Ultra's in our catalog, and the table below reflects that honestly rather than filling gaps from assumption.
Nokta publishes a 9.5 inch waterproof DD coil and vibration alerts for the Simplex Lite, and a 16 foot waterproof rating, a carbon fibre shaft and an 11 inch coil for the Simplex Ultra.
| Model | Price | Stock coil | Coil type | Vibration alert | Material |
|---|---|---|---|---|---|
| Nokta Simplex Lite | $249.00 | 9.5 in | DD | Yes | - |
| Nokta Simplex Ultra | $299.00 | 11 in | - | - | Carbon fibre shaft |
Figures are taken from each manufacturer's own published listing and specification sheet. A dash means the maker does not publish that figure for that model, not that the feature is absent.
What does the published record actually show, row by row?
Six rows, and three of them are gaps in the Lite's own listing rather than points where the Ultra genuinely outperforms it.
The Simplex Ultra publishes 16 feet of waterproofing, a carbon fibre shaft and firmware updates, while the Simplex Lite's published record in this catalog stops at coil size, coil type and vibration, leaving the rest as gaps rather than confirmed absences.
| Specification | Nokta Simplex Lite | Nokta Simplex Ultra |
|---|---|---|
| Price | $249.00 | $299.00 |
| Coil | 9.5 in DD, waterproof | 11 in |
| Water rating | Not published in this listing | 16 ft (5 m) |
| Shaft material | Not published in this listing | Carbon fibre, retracts to 25 in |
| Vibration alerts | Published as a feature | Not published in this listing |
| Firmware updates | Not published in this listing | Online, via USB on PC |
From the Nokta listings for both machines in this catalog. Nokta sells both as part of the waterproof Simplex family, and the current manual for the Lite is the place to confirm any figure not printed here.
Choose the Simplex Lite if
You are hard of hearing or detect somewhere loud, and want vibration alerts as a primary signal rather than a backup to audio. Nokta publishes vibration as a named feature for the Lite and does not publish it for the Ultra in this listing, which is a genuine, specific reason to pick the cheaper machine rather than a consolation prize. The Simplex Lite target ID chart is where to start reading its numbers.
Choose it too if the smaller 9.5 inch coil and a lighter overall build suit a smaller user, since a lighter machine genuinely reduces fatigue over a long session regardless of what else the spec sheet says.
Choose the Simplex Ultra if
You want the fully documented waterproof figure before spending money on a machine you plan to get wet. Sixteen feet of published submersion, a carbon fibre shaft and online firmware updates are all specific, checkable claims, and at $299.00 it remains one of the least expensive genuinely submersible machines in this catalog. Read Simplex Ultra settings by site type and the full Simplex Ultra review before your first hunt.
Choose it too if you want the larger 11 inch coil for open ground, since more coverage per sweep is a real, if modest, time saving over a full session.
What would help more than the fifty dollar decision?
Nokta Pointer is Nokta's own budget pinpointer and pairs sensibly with either machine, and CKG Double Serrated Hand Digger is a genuine, inexpensive first digger. Neither costs close to the price gap between these two detectors and both change a day of detecting more than the coil size does.
The beginner's guide and the best metal detectors under $300 roundup put this pairing in the context of the rest of the entry-level catalog.

Frequently asked questions
Is the Simplex Lite fully waterproof like the Ultra?
Our catalog listing for the Simplex Lite does not publish a submersion depth, while the Simplex Ultra publishes 16 feet. That is a gap in this particular listing rather than confirmed proof the Lite cannot get wet, since Nokta markets the wider Simplex line around waterproof design. Check the current Nokta manual for the Lite before relying on it in deep water.
What does the vibration alert on the Lite actually do?
Nokta publishes vibration alerts as a feature of the Simplex Lite, intended to signal a target through touch alongside or instead of audio tones. This matters most for hard-of-hearing detectorists or anyone hunting in loud conditions such as near surf or traffic, where an audio tone alone is easy to miss.
Is an 11 inch coil meaningfully better than a 9.5 inch coil?
It covers more ground per sweep and can add a little depth on larger targets, but it is also less manoeuvrable in tight or trashy spots than the smaller coil. Neither is objectively better; the Ultra's 11 inch coil suits open ground, and the Lite's smaller 9.5 inch coil suits confined or cluttered sites.
Can I put an 11 inch coil on a Simplex Lite?
Nokta builds the Simplex platform to share coil connectors within the family in many cases, but coil compatibility can change between firmware revisions and specific models, so confirm fitment against the current Nokta accessory list before buying a coil for the Lite that was designed for the Ultra.
