Richmar Winner EVO CM2 Combo Review: Professional Ultrasound & Electrotherapy in One Unit
If you're running a busy physical therapy clinic or chiropractic practice, counter space is at a premium — and so is your equipment budget. The Richmar Winner EVO CM2 promises to solve both problems by combining therapeutic ultrasound and 2-channel electrotherapy into a single, compact unit. But does this combo device actually deliver clinical-grade performance on both modalities, or does it compromise on each? We put the CM2 through its paces to find out.
Product Overview
The Richmar Winner EVO CM2 (model 410010) is a professional-grade combination therapy unit designed for clinical rehabilitation settings. It pairs a 1 MHz/3 MHz dual-frequency therapeutic ultrasound with a 2-channel electrical stimulation module supporting multiple waveforms including interferential (IFC), premodulated, Russian stimulation, TENS, and high-volt galvanic.
Richmar, based in Chattanooga, Tennessee, has been manufacturing electrotherapy and ultrasound equipment for rehabilitation professionals since the 1990s. The Winner EVO line represents their mid-tier clinical offering — positioned between basic portable units and their premium TheraTouch systems.

Hands-On Experience
Setup and First Impressions
Out of the box, the CM2 feels solid without being bulky. At roughly 7 pounds, it sits firmly on a treatment cart without sliding around, yet it's light enough to reposition between treatment rooms if needed. The build quality is noticeably better than budget combo units from overseas manufacturers — the housing feels medical-grade, not like consumer electronics.
The initial setup is straightforward. Plug in the unit, connect your ultrasound applicator to the clearly labeled port, and attach your electrode leads to the two stim channels. The backlit LCD powers on immediately with a clean home screen that separates ultrasound, electrotherapy, and combination therapy modes.
Daily Clinical Use
Where the CM2 earns its keep is in the workflow. Switching between ultrasound-only, stim-only, and combo therapy takes just a few button presses. The menu system uses a logical hierarchy: select your modality, choose the waveform or frequency, set your parameters, and start treatment. There's no digging through nested submenus for common adjustments.
The ultrasound applicator has a comfortable grip with a standard-sized soundhead. Coupling is consistent, and the unit provides audible feedback when contact quality drops — a genuinely useful feature when treating contoured areas like shoulders or ankles. Both 1 MHz (for deeper tissue penetration, up to 5 cm) and 3 MHz (for superficial treatment, 1-2 cm depth) modes perform as expected, with smooth intensity ramping.
The electrotherapy side delivers clean waveforms across all supported modes. The two independent channels allow bilateral treatment or targeting two separate areas simultaneously. Intensity controls are responsive without being jumpy — important when working with patients who are sensitive to current changes.
Combination Therapy Mode
The real value proposition of the CM2 is running ultrasound and electrical stimulation simultaneously. This combo approach is increasingly supported in rehabilitation literature for conditions like chronic tendinopathy, myofascial trigger points, and post-surgical adhesions. The CM2 handles this elegantly — you set your ultrasound parameters on one screen, your stim parameters on another, and the unit synchronizes both modalities during treatment.
In our experience, the combination mode is where this unit separates itself from clinics using two standalone devices. The time savings add up fast when you're seeing 20+ patients per day.
Pros and Cons
Pros
- Genuine space and time saver — replaces two standalone units on your treatment cart
- Reliable ultrasound output — consistent coupling, accurate intensity delivery, audible contact feedback
- Comprehensive waveform library — covers every common electrotherapy modality used in clinical PT
- Solid build quality — medical-grade housing that holds up to daily clinical use
- Intuitive interface — minimal learning curve for new staff
- Made by an established US rehab equipment manufacturer — Richmar has a track record and accessible customer support
- Reasonable warranty — 3 years on the unit itself
Cons
- AC power only — no battery option limits portability for home visits or sports sideline use
- LCD display feels dated — functional but not the touchscreen experience of newer premium units
- Accessory costs add up — replacement applicators, leads, and electrodes are proprietary pricing
- No Bluetooth or data export — no digital treatment logging or EMR integration
- Ultrasound applicator cable length could be longer for some treatment setups
- Price point sits in an awkward middle — significantly more than budget units, but lacks the bells and whistles of premium systems
Performance Breakdown
Build Quality — 8/10
The CM2 is built for clinical environments. The housing resists the inevitable bumps and gel spills that come with daily use. Ports and connectors feel secure without excessive force. The only knock is the somewhat dated aesthetic — it looks like a medical device from 2018, which it essentially is.
Ultrasound Performance — 8/10
Dual-frequency output is accurate and consistent. The pulsed mode duty cycles offer good granularity for adjusting thermal vs. non-thermal treatment effects. The contact quality indicator is a genuinely useful clinical feature. Comparable to standalone ultrasound units in the same price range. For more context on ultrasound stimulator options, the CM2 holds its own against dedicated units.
Electrotherapy Performance — 7.5/10
All advertised waveforms function as expected. The two channels are truly independent, which matters for bilateral protocols. Intensity ramping is smooth. The limitation is that dedicated e-stim units at this price point may offer more waveform customization and preset storage.
Ease of Use — 8.5/10
This is where the CM2 genuinely excels. New clinicians can be trained on the unit in under 15 minutes. The menu flow is logical, and commonly used settings are accessible without excessive navigation. If you've used any Richmar product before, the interface will feel immediately familiar.
Value for Money — 7/10
The CM2 typically retails between $1,200 and $1,800 depending on the included accessory package. That's competitive for a combo unit from an established manufacturer, but budget-conscious buyers can find basic combo units for $600-$800 (with corresponding trade-offs in build quality and support). Meanwhile, premium systems like the Chattanooga Intelect series or DJO's Empi line offer more features at a higher price point.
Who Should Buy This
- Private PT and chiropractic practices that need reliable combo therapy without the $3,000+ price tag of premium systems
- Clinics replacing aging combo units — the CM2 is a solid, modern replacement for older Richmar or Mettler units
- New practice owners building out their first treatment room who want a single device covering both modalities
- Clinicians who prioritize simplicity — if you want a unit that works reliably without a steep learning curve, this fits
Who Should Skip This
- Mobile practitioners or home health therapists — the AC-only power and 7-lb weight make this impractical for field use. Consider portable ultrasound systems instead
- Large multi-location clinics standardized on a different ecosystem (Chattanooga, DJO) — mixing ecosystems creates headaches with accessories and training
- Clinics that need digital documentation — no data export, no EMR integration, no treatment logging beyond what you manually record
- Budget buyers who only need basic TENS + ultrasound — there are functional options at half the price if you don't need the full waveform library
Alternatives Worth Considering
Chattanooga Intelect Transport 2-Channel Combo
The Intelect Transport is the most direct competitor — similar 2-channel combo format with a stronger brand presence in institutional settings. It offers a slightly more modern interface and better accessory availability but typically costs $200-$400 more. If your clinic already uses Chattanooga products, the ecosystem compatibility may justify the premium.

FAQ
Is the Richmar Winner EVO CM2 FDA cleared?
Yes. Richmar's therapeutic ultrasound and electrotherapy devices are FDA 510(k) cleared for clinical use in the United States. The CM2 is classified as a prescription device, meaning it should be used by or under the direction of a licensed healthcare professional.
Can I use the ultrasound and electrical stimulation at the same time?
Yes — combination therapy is one of the CM2's primary features. The unit allows simultaneous ultrasound and e-stim delivery, which is commonly used for treating chronic pain, trigger points, and tissue healing. You set parameters for each modality independently, and the unit synchronizes them during treatment.
What size ultrasound soundhead does the CM2 use?
The CM2 ships with a standard 5 cm² ERA (Effective Radiating Area) soundhead suitable for most clinical applications. Richmar also offers smaller applicators for treating smaller anatomical areas, though these are purchased separately.
How does the CM2 compare to Richmar's TheraTouch line?
The TheraTouch series is Richmar's premium tier, featuring touchscreen interfaces, more preset protocols, and additional modality options including laser therapy on some models. The CM2 offers the core clinical functionality at roughly 40-60% of the TheraTouch price point. For most private practices, the CM2 provides everything needed for daily treatment protocols.
Does the unit store treatment presets?
The CM2 includes factory presets for common treatment protocols across both ultrasound and electrotherapy modes. Custom preset storage is limited compared to premium units — you can save a handful of user-defined protocols, but this isn't a unit designed for extensive protocol libraries.
What's the typical lifespan of the ultrasound applicator?
With proper care (regular cleaning, avoiding drops, proper gel application), a Richmar ultrasound applicator typically lasts 3-5 years in a busy clinical setting. Replacement applicators run $200-$400 depending on the model. This is an ongoing cost to factor into your ownership calculations.
Final Verdict
The Richmar Winner EVO CM2 is a dependable, well-built combo unit that does exactly what it promises — delivers clinical-grade ultrasound and electrotherapy from a single device without unnecessary complexity. It won't wow you with cutting-edge features or a sleek interface, but it will show up every day and perform reliably across both modalities. For private practices and small clinics that want proven combo therapy capability from a US manufacturer with real customer support, the CM2 is a smart, practical investment. Compare it against clinical ultrasound machines in its price range, and the combo versatility makes a strong case. ```
