When the Stealth™ Series first launched, Couple4™ was the software that powered it. Developed in the Late 90s with upgrades through the next few decades, Couple4 ran on a Windows tablet and quickly became the backbone of the early S-Series systems. It transformed the way technicians approached shaft alignment by replacing manual calculations and reference charts with a digital, guided process. For the first time, alignment work could be performed with a mix of precision and ease that set a new standard for the industry.
By 2009, Hamar Laser advanced the concept with Couple5™, released on a PDA platform. This marked an important step forward in portability. Technicians could now carry the software into tighter spaces and more demanding industrial settings without the bulk of a larger tablet. With this release, Couple4™ was discontinued, but its innovation laid the foundation for everything that came after.
Developed in Late 2010, Hamar introduced Couple6™, returning to the Windows tablet to harness its larger display, stronger processing power, and richer graphical capabilities. Couple6™ built on everything learned from its predecessors, adding features like Easy-Guide™ navigation, high-resolution color displays, and advanced reporting tools. With its arrival, Couple5™ was retired, but once again, its portability-driven design was carried forward into the new platform.
Importantly, Hamar ensured that innovation never left loyal customers behind. All Stealth™ Series legacy systems can be upgraded to use Couple6™, giving long-time users the ability to benefit from the most advanced alignment features without investing in entirely new hardware. This consistent upgrade path highlights Hamar’s long-standing commitment: advancing technology while protecting customer investment.

Provides the ability to capture photos of the application and store them within the data file for seamless inclusion in reports, enhancing documentation and clarity.
Calculates shim and move values for flange-mounted motors by easily measuring vertical machine alignment, simply enter the flange bolt quantity and diameter, coupling diameter, and flange outside diameter.
Provides realistic, real-time updated graphics and values that display live feedback during vertical machine corrections, allowing quick reference point changes, ideal for vertical machinery adjustable at the flange.
Primarily used for vertical applications where the accelerometer cannot be used, this method records data at up to 8 “clock” positions, requiring a minimum of 3 points (4-8 recommended), with data collected at intervals of at least 45 degrees.
Automatically captures readings by rotating between any two positions with Auto or Manual start and stop sweeps, generating data points as the shafts rotates, recording up to 1,000 points per data set with a minimum sweep of 40 degrees that crosses a polar coordinate.
Allows starting and stopping at any point in the motor’s rotation multiple times, ideal for situations with obstructions blocking the laser or preventing full rotation where partial sweeps are combined as long as they total at least 40 degrees and cross a polar coordinate.
For harsh environments with high vibration, it allows rotating to any clock position to take data points, requiring at least five points, using data averaging to reduce measurement noise and accurately calculate misalignment results.
For non-rotating shaft applications, this method involves rotating the laser to any position and slowly sweeping the target past the laser to capture data points, requiring a minimum of five points, including one within 10 degrees of a polar coordinate
Stores up to 99 sets of detailed alignment results, allowing selection of individual readings or averaging multiple readings, making it ideal for unstable bases or “loose” machines, with the option to archive data points to the History table under selectable categories.
Allows entry of thermal growth offsets at the coupling so that when aligning “in tolerance,” the motor is intentionally positioned with these offsets applied, values usually provided by equipment OEMs, and is widely used in the maritime industry for accurate calculations.
Determines and applies thermal growth offsets at the feet by allowing entry of thermal growth at the coupling, expected foot value changes, or temperature changes, with machine materials selected from a built-in database, to automatically adjust misalignment values during alignment.
Temperature calculations provide precise adjustments to alignment values by accounting for temperature-induced expansions or contractions of machine components, ensuring accurate and reliable machine positioning throughout varying operating conditions.
This feature lets you move the stationary machine when the movable one can’t be adjusted, locking feet on both machines to recalculate shim and move values for bolt- or base-bound conditions, with graphical support and Duo-Plane™ functionality.
Select from seven realistic data formats for spacer shafts by choosing the coupling type and entering the spacer shaft length in Step 1, after which the results and Step 5 move data are formatted accordingly, defaulting to Gap A/Gap B, while shim and move values remain unchanged.

Assumptions for this example: You have a 480 volt motor drawing 40 amps and operating 8400 hours/year. The Power Factor is .85. Electricity costs $0.06/kWhr. Also assume that the amp draw is measured before and after the alignment and it is found that there is a 1 amp difference.
kW =V* A*PF*1.732/1000
kW =480V* 1A*.85*1.732/1000
kW =.706 = power savings
Savings ($) = operating hours * kW savings * kW cost
Savings ($) = 8400 * .706 * $0.06/kWhr
Savings ($) = 8400 * .706 * $0.06/kWhr
Savings ($) = 355.82
If your plant has 80 similar motors, and if only half of them had the same amount of savings, it would total $355.82 * .5 = $14,232!
The coupling icons next to the data displays show the direction of the misalignment at the coupling and update as you move or shim the motor! You can also zoom in on the coupling to show them in the live display area of the screen.
