Spotter — Knucklehead Radar (Hunter marksman)
Anchor: Knucklehead Radar (Helmet) · Subclass: Nightstalker (Void) · Role: Primary-weapon duelist — radar-while-ADS map control + clean-up damage on marked targets Sandbox: 9.7.0 · Created 2026-06-16
Most exotics give you an ability. This one gives you information. Radar stays live while you're aiming down sights — so you hold a long sightline, scoped in, and still see the flanker arriving. Crouch behind cover and the radar sharpens further. It's a neutral-game utility helmet, not an engine: the build is a strong primary, a Void kit that lets you reposition and vanish, and a helmet that makes sure you always shoot first. Leans Crucible, but the target-marking earns its keep in PvE too.
Loadout
| Slot | Pick | Why |
|---|---|---|
| Super | Shadowshot: Deadfall | On-theme suppress/weaken + groups a push; pick Moebius Quiver if you want a roaming PvP answer. Either way the Super isn't the build — the gun is. |
| Class ability | Gambler's Dodge (PvE) / Marksman's Dodge (PvP) | Gambler's near enemies recharges melee for the invis loop; Marksman's reloads on dodge to keep a primary topped between duels. |
| Movement | Triple Jump | Air control to peek/re-peek sightlines. (Knucklehead's small airborne-effectiveness bonus is a free top-up here, not a reason to fight from the air.) |
| Melee | Snare Bomb (Smoke Bomb) | A weaken/invis tool — Stylish wants a debuffed kill, the smoke supplies one and the escape. |
| Grenade | Magnetic Grenade (PvE) / your pick (PvP) | With Undermining it's a precise weaken delivery; in PvP run whatever you aim best. |
| Aspect 1 |  Vanishing Step | Dodging makes you invisible — the reposition button. Break a duel you're losing, relocate, re-engage with radar already back up while you ADS. |
| Aspect 2 |  Stylish Executioner | Any elemental-debuffed kill → invisibility + Truesight (see enemies through walls/smoke — the information theme doubled). Next melee while invis weakens. |
Echo of Dilation while crouched: sneak faster + enhanced radar resolution — this is the keystone, it stacks with the helmet's crouched sharpening and hands +10 Weapons/+10 Super
Echo of Obscurity finisher → invis — free vanish on a clean-up
Echo of Persistence Invis/Overshield/Devour last longer — keeps the reposition window open
Echo of Leeching melee kill → team heal — sustain off the smoke- Echo of Harvest (weakened kills → Orb + Void Breach, the PvE economy feed). Drop Harvest for Echo of Reprisal in PvP if you'd rather feed Super than orbs
Exotic — Knucklehead Radar (Helmet)
Upgraded Sensor Pack: Provides radar while you're aiming. Enhances your radar resolution while crouched. Visually marks targets. Deals more damage to low-health marked targets. Provides a small benefit to the airborne effectiveness stat of all weapons.
Four effects, one fantasy — you always have more information than the person you're shooting at. (1) Radar while ADS is the headline: every other Guardian loses their radar the instant they scope, so holding a sightline blinds them and not you. (2) Crouched resolution sharpens the blips into directional precision — pre-aim the corner before they round it. (3) Visually marks targets + (4) bonus damage to low-health marked targets is the clean-up edge: the chip you've already done gets finished faster. The marking is a neutral benefit (no ability, no cooldown), which is exactly why this is a gunfighter's helmet and not an ability build.
Why this works (the mechanics)
- Radar-while-ADS is a one-sided information war. Standard radar dies the moment anyone aims down sights. With Knucklehead you keep yours scoped in — so the duelist holding the angle (you) sees the third party coming while the person peeking you is blind. Long-range primaries (scout/pulse/HC) turn this into free first-shot advantage on every engagement.
- Echo of Dilation is the perfect-fit fragment, and it's not a coincidence. "While crouched, you sneak faster and gain enhanced radar resolution" — it stacks the same crouched-resolution effect the helmet already gives, sharpening blips into near-directional reads, and pays +10 Weapons / +10 Super for doing it. The subclass fragment and the exotic point at the identical playstyle: slow, crouched, holding an angle, reading the room before you commit.
- The low-health-mark damage is a finisher, not a DPS source. Targets you've marked take bonus damage once they're low — it speeds up the kill you'd already win, shaving the last few HP so a wounded enemy can't escape the trade. Treat it as trade-insurance, not a damage perk. (The exact bonus % isn't in the manifest — see verify notes.)
- Void gives you the two things a pure-gun build lacks: a reset and a vanish. Vanishing Step turns a dodge into invisibility — the escape valve when a duel goes sideways. Stylish Executioner turns any debuffed kill into invis + Truesight, so you can reposition and see the next target through the wall. Information on defence (radar, Truesight) and information on offence (marking) are the whole kit.
- Truesight + radar is double vision. Stylish's Truesight outlines enemies through geometry; the helmet's radar tells you where the unseen ones are. Between them you rarely get surprised — which is the entire point of an information exotic.
- It's honest about what it isn't. No grenade spam, no melee engine, no super loop. The abilities exist to support clean gunplay — reposition (Vanishing Step), sustain (Leeching), and a weaken to trip Stylish. The damage and the kills come from the primary. That's the build's identity, not a shortcoming.
Weapons
Primary-forward by design — the helmet's value scales with how much you ADS and hold angles, so the gun choice is the build.
- Best fit: a long-range primary you live in ADS with. A Scout Rifle, Pulse Rifle, or Hand Cannon — anything where radar-while-scoped is a constant edge rather than an occasional one. Pick the archetype you shoot most accurately; the exotic rewards trigger discipline, not a specific frame.
- Element is free. Run a
Void primary if you want Stylish/Harvest to fire off weapon kills more easily (debuff synergy + orbs), but any element works — the helmet is element-agnostic. - Champions (Anti-Champion 2.0): stun is intrinsic to weapon archetypes now, so cover Barrier/Unstoppable/Overload across your primary + special pick. Deadfall's suppress handles Overload behaviour and ability-spam elites; the helmet's marking just speeds up the finish once they're low.
- PvP secondary: a Special you trust for the close range the primary can't hold — shotgun/fusion/glaive to your taste. The primary is where Knucklehead pays out.
Stats & archetypes
PvP: Weapons high → Class → Health. Weapons boosts reload/handling and (post-9.7.0) damage vs minors/majors — straight value on the gun you're built around; Echo of Dilation chips in +10. Class to keep Dodge (your reposition/vanish) on a short cooldown.
PvE: Weapons → Class → Super, with Health as the dump — Vanishing Step + Stylish invis + Echo of Persistence + Leeching cover survivability, so Health is the cheapest trade. Dilation's +10 Super and Deadfall feed the tether.
Archetypes that favour Weapons/Class (Gunner/Specialist-leaning pieces) hit the targets without a god roll. Mods: primary loaders + reloaders matching your weapon, a surge matching its element, targeting mods for the precision-hit gameplay, and Recuperation/ Better Already for PvE sustain.
Set bonus (optional)
Pure garnish — the build is complete on Tier 4 gear with no set at all. If you have the rolls already: a set that buffs weapon handling / reload / airborne on your primary class complements the ADS-duelist loop, and any 2pc that nudges Class or Weapons stat just deepens what's above. Never chase a set for this build — chase the stat spread and a primary you trust. Slot a bonus only if your existing pieces happen to carry the stats.

The loop
Low-APM, position-first. The exotic rewards patience, not button-mashing.
- Hold an angle, crouched, ADS. Radar stays live and sharpened — you see the approach before they see you. Dilation + Knucklehead = you always know what's coming.
- Open the trade with the primary. Marking + the chip damage means a wounded enemy dies faster to the low-health bonus; finish before they can break the line of sight.
- Losing the duel? Dodge → Vanishing Step invis → relocate. Radar's already back up while you re-ADS from the new angle. Smoke for a weaken if you need Stylish online.
- Clean a debuffed kill → Stylish invis + Truesight → read the next target through the wall → repeat. In PvE, Harvest turns those kills into orbs/Breaches and the economy ticks over; in PvP, Reprisal feeds Deadfall for the next push.
