GAMMA Momentum 2 Drop Weight: A Compact Manual Option

The Momentum 2 is a manual drop-weight stringing machine built around a die-cast aluminum base. Its low-profile design and compact footprint can suit a smaller work area, while the included tool tray keeps common stringing tools close at hand.

Its 2-point mounting system holds the racquet in place, and composite floating clamps grip the strings. The machine also uses red-marked touchpoints and decals to guide key steps, including string placement, tension application, and weight positioning. That visual guidance may be useful if you want a straightforward setup or are still building a consistent routine.

The main trade-off is the 2-point mount and floating-clamp arrangement. The Momentum 6 Plus and ELS models offer 6-point mounting, and the 6 Plus uses fixed clamps. For a busy stringing bench, those differences may matter more than the compact design. A drop-weight system also means working with the weight as part of the tensioning process rather than using the electronic controls found on the ELS.

Pros:

• Compact, low-profile design with a die-cast aluminum base
• Visual guides help explain key setup and tensioning steps
• Tool tray includes a protective pad for organizing supplies

Cons:

• Uses a 2-point mounting system rather than a 6-point system
• Floating clamps may be less appealing if you prefer fixed clamps

Verdict: Choose the Momentum 2 if you want a compact, guided drop-weight machine and are comfortable with its 2-point mount and floating clamps.

GAMMA Momentum 6 Plus: Drop Weight with Six-Point Support

The Momentum 6 Plus keeps the manual drop-weight approach but adds a 6-point mounting system. The frame is held at more support points than on the Momentum 2, which GAMMA says helps reduce frame distortion during stringing. Its die-cast aluminum base and broad tool tray make it a more fully equipped bench option.

This model uses fixed clamps for a firm grip on the strings and a quick-action swivel base for adjustments. It also shares the Momentum line’s red touchpoints and decals, which mark steps such as placing the string in the gripper and positioning the weight. Those cues can help keep the process organized without adding electronic controls.

Compared with the ELS 6PT, the 6 Plus does not list touchscreen controls, memory presets, pre-stretch settings, or knot-tension functions. It is also still a drop-weight machine, so it suits stringers who prefer a manual process over electronic tensioning. If you want six-point support and fixed clamps without moving to the electronic model, this is the clearest fit in the range.

Pros:

• 6-point mounting system is designed to hold the racquet securely
• Fixed clamps provide a reliable grip on the strings
• Quick-action swivel base supports fast adjustments
• Guidance decals and a large tool tray help keep work organized

Cons:

• Uses manual drop-weight tensioning rather than electronic controls
• Has fewer listed tension-setting features than the ELS 6PT

Verdict: Pick the Momentum 6 Plus if you want a manual machine with 6-point mounting and fixed clamps, but do not need the ELS model’s electronic features.

GAMMA Momentum ELS 6PT: Electronic Controls for a Feature-Rich Bench

The Momentum ELS 6PT is the electronic option in this group. Its rotational tensioner is designed to deliver consistent pulls, and a horizontal milled gripper mechanism is intended to improve string handling. For a stringer who handles frequent or varied jobs, the electronic controls offer more ways to set up each pull than the manual machines do.

The touchscreen includes nine memory presets, adjustable pull speeds, pre-stretch settings, knot-tension functions, and built-in calibration tools. A 6-point mounting system with an A240 mount and Quick Change latch is designed for secure racquet setup. The machine also has a die-cast aluminum base and an oversized integrated tool tray.

Those controls make this the most feature-rich choice here, but they may be more than you need if you prefer a simple manual workflow. The drop-weight and spring-tension models avoid the ELS’s control interface and focus on mechanical tensioning. Consider whether you will use presets and adjustable settings before choosing the electronic model for those features alone.

Pros:

• Electronic tensioning with adjustable pull speeds
• Nine memory presets, pre-stretch, and knot-tension settings
• Built-in calibration tools and a 6-point mounting system
• Oversized integrated tool tray helps organize a busy bench

Cons:

• Its range of controls may be unnecessary for stringers who want a basic manual setup
• Has a more involved feature set than the drop-weight and spring-tension models

Verdict: The Momentum ELS 6PT is the strongest match if you want electronic tensioning, multiple saved settings, and 6-point mounting in one machine.

GAMMA Momentum Spring Tension: Manual Tensioning with Fixed Clamps

The Momentum Spring Tension is a manual machine with a 6-point mount, fixed clamps, and a spring winder. Its die-cast aluminum base gives it a solid platform, while the low-profile design and included tool tray are intended to keep the bench compact and organized.

Instead of a drop-weight setup, this model uses a rotational string guide, spring winder, and high-friction linear milled string grippers. GAMMA’s decals mark the main steps, including string placement and tension application. The quick-action swivel base is designed to make adjustments easier while working around the racquet.

It shares the 6-point mounting and fixed-clamp approach of the Momentum 6 Plus, but uses spring tension rather than drop-weight tension. The ELS 6PT adds electronic controls and extra tension settings, while the Spring Tension model keeps the process mechanical. The supplied details do not list electronic presets or calibration tools for this model, so choose it for its manual design rather than expecting those functions.

Pros:

• 6-point mounting system and fixed clamps
• Spring winder with a rotational string guide
• High-friction linear milled string grippers
• Quick-action swivel base and organized tool tray

Cons:

• Does not list the ELS model’s electronic controls or settings
• Manual spring tensioning may not suit stringers who prefer a drop-weight or electronic system

Verdict: Choose the Momentum Spring Tension if you want a manual 6-point machine with fixed clamps and a spring-based tension system.

How to Choose a Tennis Stringing Machine

Choose a tension system that fits your workflow

These machines use three approaches: drop weight, spring tension, and electronic tensioning. Drop-weight models use a weight as part of the tensioning process, while the Spring Tension uses a spring winder. The ELS 6PT uses an electronic tensioner and adds settings such as adjustable pull speeds and pre-stretch. Think about which process you prefer and whether the electronic features will make a useful difference in your routine.

Compare the mounting systems

The Momentum 2 has a 2-point mounting system, while the other three models use 6-point mounting. A six-point setup supports the racquet at more locations; GAMMA describes it as helping reduce frame distortion. If frame support is a priority for your stringing work, compare the 6-point machines first. Also check that the machine’s mount and setup suit the racquets you plan to string.

Consider clamp style

The Momentum 2 uses composite floating clamps. The 6 Plus, ELS 6PT, and Spring Tension models list fixed clamps. Clamp preference can shape how you work, so consider which style you are comfortable using and how it fits your desired workflow. The product details do not provide specific clamp adjustment ranges, so confirm any fine-grained requirements with the seller before ordering.

Decide whether electronic settings are useful

The ELS 6PT includes nine memory presets, adjustable pull speeds, pre-stretch, knot tension, and built-in calibration tools. These options may be helpful if you regularly switch among different stringing setups. If your work does not call for saved settings or those added controls, one of the manual models may be a better match.

Look at workspace and tool organization

All four models list a die-cast aluminum base and a tool tray. The ELS 6PT has an oversized integrated tray, while the other Momentum models describe a large tray with a protective pad. If bench space is limited, compare the compact, low-profile design noted for the Momentum machines with the space you have available for the machine and your tools.

Balance speed features against simplicity

The ELS 6PT lists a horizontal milled gripper mechanism intended to improve string handling and overall stringing speed. The 6 Plus has a quick-action swivel base, and the Spring Tension also lists a quick-action swivel base. These are different features, so consider which part of your process you want to streamline. A straightforward manual machine may be easier to match to your needs if you do not want extra controls.
