LiveDOPE Data Card + App Patent pending

Every target. Every hold. One glance.

LiveDOPE is a small digital Data Card and ballistics solver that mounts beside your scope, rides on your arm, or goes anywhere else on your gear you need it. It shows the elevation and wind hold for every target of the stage at once, reads the wind and air second by second, and updates your DOPE as they change. It keeps working when your phone is in your pocket or back in the truck.

The Data Card Patent pending

A living DOPE card where you need it

A paper DOPE card is right for one temperature, one pressure and one wind call. The LiveDOPE Data Card reads the conditions you are in. Range, elevation and a low-to-high wind hold for every target, in the order you shoot them, readable in a glance between shots.

  • DisplayBright, sharp touch screen that turns tall or wide to fit the stage
  • AirBuilt-in temperature, humidity and pressure sensors
  • LevelRifle level and target angle from its own motion sensor
  • MountBeside the scope on a rigid or folding arm. The card slides out to go in a quarterback-style arm sleeve, on a tripod, or with your spotter or partner
  • PowerRechargeable, USB-C
  • WirelessBluetooth LE to the app and to wind meters

Features

Built for competition, chasing game, and the battlefield

Holds for the whole stage

Up to 12 stages of up to 10 targets. Each target carries its own range, direction and angle, so every row is a complete hold.

Wind per target

Live wind from your meter becomes a low and high hold for each target over the last 30 seconds, or the hold right now, or an average. Your choice.

Keeps working alone

Leave the phone behind and the card carries on with your rifle data. Its built-in sensors take over temperature, humidity and pressure, so density altitude stays current. It connects straight to your wind and weather meter, or takes wind you set on the card.

Rifle level and target angle

A bubble level like the one on your scope, arrows that show which way to roll, and a screen frame that turns blue or red the moment you're off level. One-tap target angle with the rifle pointed at the target.

Stage timer

A countdown with green, blue and red flashes at the times you choose. Arm it, and it starts when you pick up the rifle and move.

Ghost mode

For non-permissive environments. The card's radio never powers up, so there is no signal to intercept, direction-find or log. Its built-in sensors take over the air, and the holds keep coming. How it works

Match book in, stages out

Photograph the match book pages and the app reads the stages, targets and distances for you to check.

True your data

True the ballistic coefficient from your real drops or from measured velocities, and the card uses it from then on.

Centerfire, rimfire and air gun

One solver for your match rifle, your .22 and your air rifle, each worked out the way its round actually flies. Switching asks you to confirm, on the phone and on the card, so you never shoot one rifle's DOPE from another.

Ghost mode Emissions control

No signal to find

On today's battlefield, anything that transmits can be found. Bluetooth gear left on keeps announcing itself several times a second, and any receiver in range can log it, fingerprint it and take a bearing on it. Direction finding turns that into a location, and a location can become a target.

Ghost mode is the Data Card's answer for EMCON: it does not just stop sending. The card restarts with its radio never switched on: no Bluetooth advertising, no connection to a phone, no searching for meters, no Wi-Fi. There is no radio signature from the card to collect.

  • RadioNever powered in Ghost mode. Nothing to intercept, direction-find or log
  • HoldsStill live. The card's built-in sensors take over temperature, humidity and pressure, so density altitude stays current. Wind is set on the card, and the rifle level keeps working
  • Stays darkKept through power-off. It stays in Ghost mode until you turn it off on the card itself; no phone or remote command can switch the radio back on
  • LightPair it with NV mode: dim greens and a low brightness for light discipline

Ghost mode controls the card's own emissions. Phones, radios and meters are separate emitters: manage them under your unit's EMCON plan. Like any powered electronics, the card gives off faint electrical noise that only specialist equipment at very close range can pick up.

The LiveDOPE app Patent pending

Set it up on the phone. Shoot from the card.

The app holds your rifles, your stages and your meters. It solves every target with a full ballistic engine and sends the card live holds every second while they are connected.

  • Rifle profiles for centerfire, rimfire and air gun, locked until you choose to edit them
  • Stages from match book photos, typed in, or built on the card
  • Direction of fire from the phone's compass
  • Wind and air from your meters, or entered by hand
  • Card settings, columns and timer set from the phone

Android app now. iPhone coming soon.

LiveDOPE app: wind 8 mph from 3 o'clock, air values, and holds for four targets

Works with your meters

Wind and air, straight from the meter

Connect a meter to the phone or straight to the card. Use a wind meter and an air unit together, and LiveDOPE takes the air from one device when it can.

  • Kestrel 5000 series, including the 5500 and 5700 Elite
  • Kestrel DROP for temperature, humidity and pressure
  • WeatherFlow WEATHERmeter
  • Calypso Ultrasonic Portable Mini
