NMX-TGT-30 · ENGINEERED TO ORDER — AUTOMATED TARGET & SHOT-LOCATION SYSTEM

Where it hit. Where it missed.

Name: Automated Target & Shot-Location (LOMAH) System
Brand: Neometrix

A paper target records only what struck it. The instructor three hundred metres back cannot see where the rest went — so a firer spends a morning learning the results of a fraction of the rounds fired. LOMAH ends that: every round in flight carries a supersonic shockwave ahead of it, an array of acoustic sensors below the target line times its arrival at each sensor, and the differences place the shot in the target plane to millimetre class — misses as well as hits. Around it: turning, falling and running target mechanisms; lane displays and an instructor’s console running practices written to the syllabus; per-firer records that make a year of training measurable. And the point everyone who has stood a range detail remembers — nobody goes downrange to mark any more. Outdoor field firing ranges first, and retrofit into the ranges units already have. Engineered to order — no delivered system is claimed.

Overview

The misses are the lesson.

Marksmanship is taught by correction, and correction needs to know what went wrong. A target that records only hits answers the easy half of the question — the shots that were already good. The shots that missed, and by how much and in which direction, carry every piece of information an instructor actually needs, and until recently they simply vanished into a berm. Shot-location systems recover them. That is the whole idea: not a scoreboard, but a measuring instrument pointed at the one part of training that used to be invisible.

Illustrative image, not a delivered system — close view of a rugged acoustic sensor bar on a firing range: a horizontal olive-grey aluminium housing about a metre long with a row of small circular sensor ports along its front face and a sealed cable gland at one end, bolted to two short galvanised stakes in the grass, morning dew on the housing, the lower edge of a plain canvas target frame out of focus behind, no people and no text

Fig · 02 The sensor bar — a surveyed line of microphones that hears the shockwave before anything else does — illustrative, not a delivered system

How the measurement works. A round travelling faster than sound drags a shockwave behind its nose — the crack heard on a range, distinct from the report of firing. That wave reaches the target line before anything else and spreads outward at a known speed. An array of acoustic sensors in a surveyed geometry below and beside the target records the instant the wave arrives at each one; the differences between those arrival times are solved for the point in the target plane the round passed through. The result is a coordinate, delivered in the time it takes the firer to settle back onto the sights — and it exists whether or not anything was struck.

Geometry is the measurement. Everything the system claims rests on knowing where its sensors are relative to each other and to the target frame. So arrays are surveyed on the range, not calibrated on a bench, mounted on foundations that do not creep with season or soil, and re-verified as a matter of routine — because a sensor that has shifted does not fail visibly. It returns a confident, precise, wrong answer, which is the most expensive failure mode an instrument can have.

Around the sensors, the mechanisms. Practices are built from exposures: a target that turns edge-on to full-face for a set time, one that falls when struck, one that runs across the lane on a rail. These are outdoor machines that live a few metres from where rounds land, so the engineering is unglamorous and decisive — sealed pneumatic or electric drives, hardened housings, corrosion protection for monsoon and salt, and modules a unit can replace itself without waiting for a contractor to travel.

The modular ranges on this site are the structure; this page is what goes inside them — and, far more often, what gets fitted to the outdoor field firing ranges a unit has had for thirty years.

Every Shot

Hits and misses alike

The array places every round through the target plane — the misses included, which is the information coaching actually runs on.

Nobody Downrange

The butts, retired

Scoring once meant a person marking each shot between details. Sensors ended that — returning both the safety margin and the hours.

The Record

A year, measured

Per-firer, per-practice results turn a morning’s impressions into a training record a unit can actually manage against.

Architecture

The crack arrives, the array answers.

The schematic follows a single shot — fired on the point, its shockwave reaching the target line, the array timing it, the coordinate and score returned — and shows the machines behind it: the target mechanisms, the sensor array, the lane displays and console, and the range network that ties lanes hundreds of metres out to the control end.

Specifications

Reference installation, built to the range.

The parameters below describe a reference system. The lane count, distances, target types, sequences and network all follow from three givens: the range as it exists, the practices the syllabus requires, and the calibre classes fired on it.

Where target systems go wrong

Almost never in the physics. A sensor array is a timing problem solved long ago; what fails is everything around it. Arrays surveyed once and never re-verified drift with soil and season and then report precise nonsense. Systems score hits handsomely and shrug at misses — abandoning the only reason to buy one. Downrange electronics specified as though they will live in a laboratory meet their first monsoon and lose. Links and power fail on the morning the range is booked, and thirty people stand about. And retrofit is treated as an afterthought by designs that quietly assume a new range, when the actual requirement is nearly always to instrument a range that has stood for decades.

So the discipline is dull and deliberate. Geometry is surveyed on site and re-verified on a schedule, on foundations chosen for the ground. Misses are first-class data, not an exception path. Downrange hardware is specified for sun, dust, monsoon, salt and stray rounds, with field-replaceable modules. Links are designed with a fallback and a fail-safe stance — a fault stops the practice safely, never ambiguously. The console is built for an instructor running a detail, not for an engineer. And the whole system is drawn to fit the range that exists, its distances, its lanes and its power.

FAQ

Common questions.

Plain-language answers from the engineering team.

Q · 01 What does LOMAH actually mean, and why is locating a miss the point?

LOMAH stands for location of miss and hit, and the order of those words is the whole argument. Traditional scoring can only report what physically marked the target — so a shot that passed a hand’s width outside the frame and a shot that went ten metres wide are recorded identically, as nothing. But those two shots mean completely different things: one is a firer who needs a small correction and will get there in minutes; the other has a problem with position, sights or fundamentals that will not be fixed by encouragement. Without the misses, an instructor is coaching half-blind — and the half that is invisible is precisely the half that needs teaching. A shot-location system measures where every round passed through the target plane, whether or not it struck anything, so a group can be seen as a group: its centre, its spread, and its direction of error. That is what turns a range detail from a test into a lesson. It also changes the tempo of training, because the correction arrives while the firer is still in position and still remembers what that shot felt like — rather than at the end of a detail, attached to a number.

Q · 02 How do acoustic sensors work out where a shot went?

By timing a sound that arrives before any other. A round travelling faster than sound carries a shockwave with it — the sharp crack heard downrange, quite separate from the report of firing, which arrives later and from a different direction. That shockwave spreads outward from the round’s path at a known speed. An array of acoustic sensors, mounted in a precisely known geometry below and beside the target, each records the instant the wave reaches it. Because the wave reaches a nearer sensor sooner than a farther one, the differences between arrival times constrain where the round must have passed; with enough sensors in the right arrangement, those constraints resolve to a single point in the target plane. Practical accuracy is millimetre class over a normal target face — far finer than any shooter’s natural dispersion, which is the requirement, since the instrument must never be the limiting factor in what it measures. Two conditions matter. The round must be supersonic at the target, which the ordinary service calibre classes comfortably are at normal training distances. And the sensor geometry must be exactly what the system believes it is — which is why survey and re-verification, not sensor quality, is where accuracy is actually won or lost.

Q · 03 Can this be fitted to a range we already have?

Yes — and that is the normal case rather than the exception. Most establishments are not building ranges; they have ranges that have been in use for decades, with known distances, an established firing point, a berm and a safety template that has already been approved. What they lack is instrumentation. A retrofit starts with a survey: the existing lanes and distances, the ground conditions where sensor arrays and target mechanisms will be founded, the available power at the firing point and downrange, and the route a link can take. From that come the arrays and their foundations, the target mechanisms suited to the practices actually run, the link back to the control end — wireless where trenching is impractical, buried cable where it is not — local power downrange, and a console and displays at the firing point. The range’s existing safety case is respected rather than reopened, because nothing about the firing geometry changes; what changes is that the range now measures what happens on it. Retrofit is also how a unit can instrument progressively — a few lanes first, more later — provided the network and console are specified from the start for the range’s eventual full width.

Q · 04 How does downrange equipment survive sitting next to where rounds land?

By being designed for it rather than protected from it. Anything downrange faces two separate problems, and confusing them produces equipment that fails in service. The first is the environment: sun and ultraviolet, dust, monsoon, standing water, salt near the coast, temperature swings, and vegetation and small animals that treat any enclosure as an opportunity. That is answered with sealed housings, drainage and ventilation designed so condensation cannot pool, corrosion-protected fasteners, cable glands and buried routes that no strimmer will find, and lightning and surge protection — a target line is often the tallest thing on a flat range. The second problem is proximity to the impact area: sensor bars and mechanisms sit close to where rounds are meant to go, which means near-misses and ricochet fragments are routine, not exceptional. That is answered with hardened housings and sacrificial elements — components positioned so the parts most likely to be struck are the cheapest and quickest to swap. Which leads to the design rule that matters most in service: everything downrange is field-replaceable by a unit’s own people, in an hour, with hand tools. A range that waits three weeks for a contractor to change a module is a range that quietly goes back to paper targets.

Q · 05 What does the instructor actually get — and what happens to the results?

At the firing point, a lane display beside each firer showing each shot as it is placed, with the developing group, and a console at the control end from which the whole detail is run. The console’s job is to make a practice easy to run under pressure: programmable sequences written to the training syllabus — exposure times, orders of appearance, timed and untimed practices, day, night and low-light modes — selected and started without menu archaeology, because thirty people are waiting and light is going. It also holds the safety-adjacent controls the instructor expects to reach without looking. Afterwards, results become a record: per firer, per practice, per lane, with grouping and score history that turns a year of training from a set of remembered mornings into something a unit can actually manage — who has fired, who has improved, who needs coaching before classification. Where an establishment runs its own training-management system, results export into it rather than living in an island database. That record is, in the end, most of the value: the coaching happens on the day, but the evidence of a unit’s marksmanship over time is what a commander is asked for, and it cannot be reconstructed later.

Q · 06 What do you build, and what is bought-in?

We build the range’s instrumentation as a system, from franchises this workshop already runs. What Neometrix does: the sensor arrays — housings, mountings, foundations and the on-range survey that makes their geometry true; the target mechanisms — turning, falling and running units, drives, controls and hardened housings; the lane displays and instructor’s console — enclosures, layout, practice sequencing and the records; the range network and power — links, downrange power, control shelter, surge and lightning protection; the retrofit engineering into ranges already built; and installation, commissioning, verification, spares and AMC through life. What is bought-in certified: acoustic sensors and timing modules, display hardware, drives and standard network components with their certificates. The structures side of range work — the modular indoor ranges themselves, their containment and air systems — is covered on its own page; this one is what goes inside them and, more often, what gets fitted to the outdoor ranges units already have. Engineered to order; quoted across LOMAH, automated small-arms target and smart-target-system requirements; no delivered system is claimed on this page.
