The Chattanooga Intelect Transport Combo is a portable combination therapy unit manufactured by DJO Global (Chattanooga Group). It integrates:
- Therapeutic ultrasound — 1 MHz and 3 MHz frequencies, continuous and pulsed modes
- 2-channel electrical stimulation — supports multiple waveforms including IFC, Russian, TENS, premodulated, and high-volt galvanic
- Compact, carry-handle design — the "Transport" name is literal; this unit is designed to move
Intended users: Physical therapists, sports medicine clinics, chiropractic practices, and athletic training rooms that need both ultrasound and e-stim in a single portable form factor.
Typical output specs:
- Ultrasound intensity: 0–3.0 W/cm²
- Transducer frequency: 1 MHz / 3 MHz switchable
- Beam non-uniformity ratio (BNR): ≤6:1 (verify on unit-specific calibration records)
- E-stim channels: 2 independent channels
- Carrier frequencies vary by waveform mode
Hands-On Experience
Setup and Learning Curve
Out of the box (or more accurately, out of the used-equipment shipping box), the Intelect Transport lives up to its name. The carry handle is robust, the unit sits flat on any treatment table, and the control interface uses membrane buttons with a backlit display — not a touchscreen, which means fewer calibration headaches and no cracked glass after years of clinical use.
The interface is organized by modality. You select Ultrasound, Stim, or Combo from the top-level menu, then dial in parameters. For experienced clinicians, this is intuitive. For staff unfamiliar with Chattanooga's menu logic, expect a 30-minute orientation session. The user manual is widely available online if one wasn't included with your purchase.
Daily Clinical Use
In a typical outpatient orthopedic setting, the combo mode is where this unit earns its keep. Running ultrasound over a rotator cuff while simultaneously delivering IFC to the surrounding musculature — without juggling two machines — saves treatment time and simplifies documentation. The 2-channel stim allows for crossfire techniques or independent bilateral treatment.
The 1 MHz / 3 MHz switchover is straightforward. Deeper tissue targets (hip, shoulder, lumbar) call for 1 MHz; superficial structures (wrist tendons, plantar fascia, knee ligaments) respond better to 3 MHz. The unit handles both without issue.
One notable characteristic: the unit runs warm during extended ultrasound sessions. This is normal for a therapeutic ultrasound generator of this class, but if the unit feels unusually hot or the transducer output seems inconsistent, that's a signal to have it calibrated — which brings us to the single most important purchasing consideration for this unit (see Cons below).
Applicator and Transducer Notes
The standard applicator for this unit is a 5 cm² soundhead, which handles most clinical applications. A 1 cm² soundhead is available for smaller treatment areas. When purchasing used, always confirm whether the original applicator is included — replacement Chattanooga-compatible soundheads are available, but they add $150–$400 to your cost basis depending on source.

Pros and Cons
Pros
- Proven clinical track record — The Intelect Transport has been in physical therapy clinics for well over a decade. Reliability data exists; it's not an unknown quantity.
- True combo operation — Simultaneously delivers ultrasound and e-stim, not just alternating between them
- 2 independent stim channels — More versatile than single-channel competitors at the same price point
- Portable without sacrificing output — Lighter than cart-based systems, heavier-duty than budget handhelds
- Strong used-market availability — Widely available refurbished; replacement parts and service networks exist
- Menu-driven interface is durable — Membrane buttons outlast touchscreens in clinical environments
Cons
- Calibration is non-negotiable — Any used ultrasound unit can drift from its rated output. A unit outputting 60% of labeled intensity is delivering subtherapeutic dosing. Always budget for third-party calibration ($75–$150) when buying used.
- No touchscreen or modern UX — Compared to newer units like the Metron or Enraf-Nonius Sonopuls series, the interface feels dated
- Aging platform — DJO has moved toward newer product lines; long-term parts availability for older serial numbers is uncertain
- No built-in timer visible from distance — Clinicians working across the room can't glance at remaining time
- Used pricing is wide — $625 to $2,400 for "the same unit" reflects vastly different conditions; buyer research is essential
Performance Breakdown
| Aspect | Rating | Notes |
|---|---|---|
| Ultrasound output | ★★★★☆ | Strong when calibrated; verify on purchase |
| E-stim versatility | ★★★★★ | 2-channel, multiple waveforms — genuinely useful |
| Portability | ★★★★☆ | Carry handle + compact footprint; not featherlight |
| Build quality | ★★★★☆ | Clinical-grade construction; membrane buttons age well |
| Value (used market) | ★★★☆☆ | Depends entirely on condition and calibration status |
| Interface usability | ★★★☆☆ | Functional but not intuitive for new users |
Who Should Buy This
- Established PT clinics looking to add a second combo unit or replace an aging machine without the cost of new equipment
- Mobile physical therapists who need both modalities in one portable package for home visits or on-site athletic training
- Sports medicine programs (high school, collegiate) where budget is constrained and the unit will get regular but not daily use
- Buyers with calibration access — if you can get the unit calibrated post-purchase, used Intelect Transports represent solid value
If you're comparing this against other portable ultrasound units, factor in whether you need e-stim integrated or if standalone therapeutic ultrasound fits your workflow better.
Who Should Skip This
- Clinics with high daily throughput — For 8+ patients per day on this unit, a newer dedicated machine with better UI and warranty coverage is the smarter long-term investment
- Buyers who can't verify calibration — If you're purchasing from an auction without calibration records and can't test output, the therapeutic value is unknown
- Practices needing 4-channel stim — The 2-channel limitation is real; for complex neuromuscular re-education programs, look at the Intelect Advanced or competitors with 4+ channels
- Anyone expecting manufacturer support on legacy serials — DJO has transitioned focus; if ongoing manufacturer support matters to you, buy new
Alternatives Worth Considering
1. Chattanooga Intelect Advanced Combo
The big brother to the Transport. Adds a larger display, expanded waveform library, and 4-channel stim option. Typically $800–$1,800 used, and worth the premium if your clinic has complex stim protocols. Check current availability: eBay search.
2. Metron Combination Therapy Unit
Metron's combo units offer a more modern interface at a comparable price point. Less name recognition, but strong clinical output specs and good parts availability. Worth comparing if you find the Chattanooga UI frustrating.
3. Enraf-Nonius Sonopuls 492
A European-standard combo unit with a reputation for accurate ultrasound output and a cleaner user interface. Less common in the North American used market, but when available, it competes directly with the Intelect Transport at similar price points.

Where to Buy
The Chattanooga Intelect Transport Combo 2-Channel is no longer in active production, which means the used and refurbished market is your primary source.
Current market price range: $625 – $2,400 depending on condition, included accessories, and seller type (dealer vs. individual).
eBay is the most active marketplace for this unit. Filter by "Buy It Now" and prioritize sellers with return policies. Units from medical equipment dealers (vs. individual sellers) are more likely to include calibration documentation.
Amazon occasionally lists refurbished clinical equipment from third-party sellers — worth checking for pricing comparison.
Buying tip: At the $625 price point, treat the unit as cosmetically used with unknown output. Budget $100–$150 for calibration. At $1,800–$2,400 from a reputable dealer, expect calibration certification and a short warranty — and negotiate if neither is included.
FAQ
Q: Can the Chattanooga Intelect Transport run ultrasound and e-stim at the same time? Yes — that's the core value proposition of the combo mode. Both modalities operate simultaneously through their respective applicators. You select "Combo" from the mode menu and set parameters for each independently.
Q: What applicator size does this unit use? The standard soundhead is 5 cm². A 1 cm² soundhead is optionally available for smaller treatment areas like the wrist or plantar fascia. Confirm which is included before purchasing used.
Q: How do I know if a used unit is calibrated? Ask the seller directly for calibration records. A reputable medical equipment dealer will provide documentation. If no records exist, budget for independent calibration through a biomedical engineering service after purchase. Do not assume output accuracy without verification.
Q: Is the Intelect Transport the same as the Intelect Legend or Advanced? No. The Transport is the portable mid-range model. The Intelect Legend and Advanced are higher-specification units with more waveform options, 4-channel stim, and larger displays. They are related product lines but not interchangeable.
Q: What waveforms does the 2-channel stim support? Typical waveforms include interferential current (IFC), premodulated IFC, Russian stimulation, TENS (conventional and burst), high-volt pulsed galvanic stimulation (HVPGS), and microcurrent. Exact waveform library depends on firmware version — confirm with the seller or DJO's product documentation.
Q: Is this unit suitable for home use? The Intelect Transport is designed and FDA-cleared for clinical use by licensed practitioners. It is not intended or marketed for consumer/home use. If you are a clinician using it in a home-visit context, confirm your malpractice coverage addresses portable equipment used off-site.
Final Verdict
The Chattanooga Intelect Transport Combo 2-Channel is a solid, battle-tested piece of clinical equipment that earns its place in PT clinics where portability and dual-modality treatment matter. Its weaknesses are primarily about age — the interface is dated, manufacturer support is winding down, and used-market condition varies wildly.
Buy it if you can verify calibration, you're getting a complete unit with applicator, and the price reflects the actual condition. At $625–$900 for a working, calibrated unit, it remains good value. At $2,400 for an uncertified used unit, you're likely overpaying versus newer alternatives.
Our recommendation: Source from a reputable medical equipment reseller, confirm calibration documentation is included, and this unit will serve your clinic reliably for years. ```
