LB Altimeters · Bluetooth audible altimeter
The Bluetooth audible for jumpers who want more freefall separation points without moving to PROTRACK 3. QUATTRO 3 gives you a fourth high-speed warning, Track Guide tones and four memory banks, then lets you set it and review its latest jumps through JumpTrack.
3 climb · 4 freefall · 3 canopy / low-speed warnings
50 jumps
Freefall computer & JumpTrack
The altimeter retains the latest 50 jumps. Connect it to JumpTrack by Bluetooth to review the data and keep your logbook current.
Designed for an audible-first setup
QUATTRO 3 is the step up for a jumper who wants a fourth high-speed alarm for a more detailed freefall plan.
Three climb-to-altitude warnings reach 19,900 ft; four high-speed warnings reach 29,900 ft; and three canopy-descent/low-speed warnings reach 19,900 ft. Track Guide uses 0.5-second beeps between the first and second high-speed warnings.
Pair with an iPhone, iPad or Android device to move setup and jump review from helmet buttons to the JumpTrack app.
Set warning altitudes, altitude offset, units and alarm volume in the app, then keep the device focused on the jump.
A thin curved housing with built-in mounting holes is made to sit inside or outside a compatible skydiving helmet.

Specifications
Before you jump
Choose QUATTRO 3 if a fourth freefall warning helps you make your normal jump plan clearer—especially for tracking groups, waves or a more detailed break-off sequence.
Choose QUATTRO 3 when you want a fourth high-speed/freefall warning, higher freefall settings and Track Guide tones. OPTIMA 3 has three warnings in each phase.
Yes. OPTIMA 3, QUATTRO 3 and PROTRACK 3 connect to JumpTrack on compatible Android and iOS devices through Bluetooth®. Use the app to set warnings and altitude offset, import the latest jumps, and maintain a digital logbook.
QUATTRO 3 stores the last 50 jumps in first-in, first-out order. You use JumpTrack to access and import them; the device retains the latest-jump records after download.
LB specifies 2 × RENATA CR-2325 batteries for these models, included. LB recommends RENATA-brand replacement batteries.
The L&B QUATTRO 3 is the Bluetooth audible for jumpers who want an extra freefall warning without moving to PROTRACK 3. It gives you three climb-to-altitude warnings, four high-speed/freefall warnings and three canopy-descent/low-speed warnings, with four memory banks for different jump plans.
The fourth high-speed warning is the reason to choose it over OPTIMA 3. It is useful when you want a more detailed freefall plan for tracking groups, waves or a structured break-off sequence. Track Guide uses 0.5-second beeps between the first and second high-speed warnings.
Pair QUATTRO 3 with JumpTrack on a compatible iOS or Android device to set warning altitudes and altitude offset, then import the latest jumps for altitude, speed and accelerometer review. JumpTrack also provides a USPA-approved digital logbook, cloud backup and email export.
The built-in freefall computer keeps the latest 50 jumps in first-in, first-out order. They remain stored on the device after download and are accessed through JumpTrack.
Read the official manual before use. An audible is a backup awareness tool and does not replace visual altitude awareness or your own deployment decision-making.
