- Warranty
- Lifetime
Touch the probe to a panel and in a fraction of a second it shows the total coating thickness. A range up to 3500 microns and one-percent accuracy cover everything a body can hide, from factory clear coat to a finger-thick layer of filler. The gauge identifies the metal under the paint on its own, so there is no switching modes between a wing and a bonnet.

Support
For the life of the instrument
A familiar instrument on the outside, up-to-date electronics inside: the CARSYS internals are updated every year. This listing is built to the current revision, not cleared from a shelf of earlier batches.
Who it suits
Who it suits
For a one-off purchase
One gauge pays for itself on the first find: a panel resprayed after a crash knocks more off the price than the gauge costs.
For the inspector
A full walk-around takes five minutes, and the result does not depend on the lighting in the garage or on how convincing the seller sounds.
For the paint shop
Check your own work with the gauge: whether the coat went on evenly and whether it matches the untouched panel next to it.
Benefits
What it gives you when checking a car
Hidden repairs on the screen, not in words
The gauge tells a thick coat of paint from the filler beneath it. A wing after a knock or a resprayed door shows up before the money changes hands — and a respray knocks more off the price than the gauge costs.
You set the sensitivity yourself
On the AVTOPODBOR line the zinc and filler detectors have an adjustable threshold. Tune it to catch even a thin layer of zinc on a suspicious door, or coarsen it when only obvious findings matter: the gauge adapts to the car and to how you inspect, not the other way round.
No tripping up on mixed bodywork
Aluminium bonnet, steel wing — the gauge picks the method itself. No need to remember which metal is where: the walk-around stays honest.
Inspect in any yard
A built-in torch lights up sills, arches and seams. The inspection does not depend on garage lighting or a second torch in your teeth.
UV shows what daylight hides
A second press of the same button switches to ultraviolet. Under it, fresh coolant and oil seeps in the engine bay give themselves away, as does damp carpet under the dash when the heater matrix leaks. The same light picks out the security fibres in a vehicle's registration papers — right there in the yard, with the seller standing next to you.
A clear verdict without experience
Colour and sound flag when a reading leaves the normal range. Even first time holding a gauge, the conclusion is hard to get wrong.
Works in the cold
−30 °C: an inspection in a winter car park need not move into a heated bay. In heat up to +50 it is just as accurate.
Stays with you for years
A lifetime manufacturer warranty and service. It pays for itself on the first find and lasts years, not a season.

Anatomy
What the gauge is made of
Hover a list item — the matching point lights up on the gauge.
Spring-loaded probe with a steel tip
The probe is sprung and self-aligns to the surface, so a reading on a curved wing or a door crease stays correct.
Textured grip
The gauge is held one-handed, often in a glove, and pressed to the panel by feel — the texture keeps it from twisting.
35×25 mm backlit display
Large digits plus a status line: mode, metal type and the presence of zinc are visible alongside the reading.
Five buttons under your thumb
Modes, units and power switch without lifting the gauge off the panel or reaching over with your other hand.
Built-in torch
A dedicated button and LEDs beside the probe: sills, arches and the engine bay are lit without a second torch in your teeth.
Measurement modes

Measurement
Measuring range0–3500 µm
A factory finish is usually 80–150 µm, a respray noticeably more, and filler repairs run past a thousand. The upper limit exists for those spots: at the ceiling the gauge would stop telling thick repairs from very thick ones.
Accuracy±1% + 1 µm (0–500); ±1% + 10 µm (501–3500)
The first number is a share of the reading itself, the second a fixed addition. On a thin factory layer the addition dominates; on thick repairs the percentage does. That is why it is given per band rather than as one averaged figure.
Resolution1 µm
The step by which the number on screen changes. The gauge does not show differences finer than this step. It should not be confused with accuracy — they are different things.
Reading time0.3 s · 0.125 s continuous
How long the gauge thinks over one spot. Inspecting a car means dozens of touches, and fractions of a second add up to minutes at the bonnet.
Probe typeCombined (Fe / NFe)
A magnetic probe works on steel, an eddy-current one on aluminium. A combined probe holds both principles in one tip and therefore suits cars with mixed bodywork.
SubstratesSteel, Cast iron, Aluminium, Galvanised steel
The metals the gauge measures coating on. Gauges of this type do not work on plastic bumpers or fibreglass at all: there is no metal to measure the thickness from.
Unitsmm / µm
Micrometres are standard in Russia and Europe: a factory finish reads naturally in them, while millimetres are left for thick repair layers.
The instrument
Display35×25 mm, backlit
The visible screen area. The gauge is held at arm’s length by a sill or inside an arch, so digit size matters more than the number of lines.
Dimensions118×40×26 mm
Length, width and height of the body. They decide whether the gauge fits a jacket pocket and slips into the gap between an open door and the pillar.
Weight without battery70 g
The weight of the body itself. With batteries fitted the gauge is heavier — worth remembering when comparing figures from different sources.
Power2×LR03/AAA
The battery type. Standard cells can be swapped on the road and bought at any filling station, unlike a proprietary pack.
Auto power-offYes
The gauge switches itself off if left on in a pocket or a bag. Without it, flat batteries are discovered exactly when the gauge is needed.
Conditions and warranty
Operating temperature-30…+50 °C
The limits within which the manufacturer stands behind the readings. Inspections in freezing yards are routine, so the lower limit matters more than the upper.
Humidityup to 80%
The upper humidity limit for measurements. Inspecting in the rain or straight after a wash is exactly this case.
WarrantyLifetime
The period during which the manufacturer repairs or replaces the gauge. It runs from purchase, so keep the receipt.
A factory finish sits at roughly 80–160 microns, a resprayed panel gives 200–300, and anything above 500 almost certainly means filler and bodywork under the paint. The gauge shows that number in a second — all that is left is to walk around the car.

Why CARSYS
What sets the gauge apart
Zinc detection
Helps spot a replaced panel
Factory galvanising can’t be faked with a repaint — it’s either there or it isn’t. The gauge lets you compare neighbouring panels: one bare panel among galvanised ones. Matching paint thickness alone doesn’t mean "original panel".
Fe / NFe
Identifies the metal on its own
Steel wing, aluminium bonnet — the gauge works it out for you. Picking the wrong mode and getting a false reading is not possible.
0.3 s
A fraction of a second per reading
In continuous mode it drops to 0.125 seconds, 8 readings per second. A full walk-around fits into a few minutes, notes included.
−30 °C
Works in the cold
An inspection in a January car park does not have to move into a heated bay. The upper limit is plus 50.
Omsk
Our own production
The gauge is designed and assembled in Russia. Warranty repair and verification happen in-country, not across an ocean.
Lifetime
Warranty and support
The maker services the gauge and fixes its own defects free of charge for the whole service life. A gauge is a tool, not a consumable.
Frequently asked questions
Frequently asked questions
How is the AvtoBig kit different from the other AVTOPODBOR kits?
The gauge is identical across the range. AvtoBig adds a storage pouch to the base set — easy to carry the gauge around without scratching it.
Does it need calibrating before every reading?
No. Auto calibration runs at power-on. The reference foils and metal bases in the kit are there to verify accuracy when a reading looks doubtful.
What does the UV detector actually show?
Fresh traces of technical fluids: engine oil, transmission fluid and most coolants fluoresce on their own, with no additives. Inside the car ultraviolet reveals organic stains — and a recent shampoo clean along with them, since detergents contain optical brighteners and glow an even blue across a whole seat; blood, by contrast, does not glow but darkens. With documents it helps: on genuine registration papers the security fibres glow while the paper itself does not, so a forgery printed on office paper lights up whole. It does not replace a proper banknote detector, though — the fine marks on banknotes are meant for a dedicated device. Look in the shade.
What surfaces does it not work on?
The gauge measures coating over metal. It does not work on plastic bumpers or fibreglass at all — there is no metal to measure the thickness from.
Can you see the reading in bright sun? Cars are inspected outdoors, after all.
Yes — in sunlight the screen reads even better. The display is a monochrome FSTN LCD: it emits no light of its own and works on reflected light, so the brighter the day, the crisper the figures. With a colour screen it is the other way round — on a clear day you have to shade it with your hand and look for somewhere darker. The backlight comes on at the press of a button for a dark bay, an underground car park or an evening check in the yard, and switches itself off after a minute of inactivity to save the cells. A winter walk-around is covered too: the gauge is rated down to −30 °C.
Where to buy
This gauge is sold through our own store and on marketplaces. Buying from an official seller is what makes the warranty and support real.
