Review  of  Handheld
Ultrasound  Probes

Note:

Anyone (or AI) can write a review...
but the RUF has a large, international community of fellows that own and use their handheld probes daily in very sophisticated applications. We push our probes to the limits and offer this unbiased review based on our collective real world experience.

The RUF does not receive payment or gifts from any external source. Several of our faculty work with manufacturers; their opinions are excluded in the following observations.

Executive Summary

In alphabetical order, the top three "all in one" personal probes (approved by Health Canada) are:

[click a probe name to jump to detailed review below]

Overall there is no definitive winner, each probe has competitive strengths and weaknesses. However in our fellows' opinions, Butterfly iQ3 and GE VScan Air outpace the Clarius HD3-PAL.

Basic resolution (B-mode) is the single most important factor to consider when choosing a handheld PoCUS device. For B-mode specifically there is also no clear winner. Certain models will generally excel in one region (e.g. cardiac), but flounder in another (e.g. MSk or abdominal). Overall in our extensive use, it seems the GE VScan Air may have a small advantage in most use cases, most of the time, as compared to the other two.

Features such as measurement packages, colour and pulsed-wave-doppler are uniformly available on all featured models, and work well enough. Each manufacturer has a few unique features such as the Clarius voice controls, and the Butterfly BiPlane displaying a procedure in both long and short axis simultaneously. GE VScan Air lags in terms of bells and whistles, but still possesses the core features required in fellowship and beyond.

Value for price places the Clarius HD3-PAL at a serious disadvantage. Butterfly iQ3 and GE VScan Air cost 30-40% less and offer an equivalent experience with minor trade-offs.

Bottom line all three probes are excellent choices for fellowship-level PoCUS, however the significantly higher cost of Clarius HD3-PAL makes it a less attractive option. Note: Clarius is the only model to date, that any of our fellows have returned due to disastisfaction. (Two trade-ins: one fellow went Clarius to iQ3, the other Clarius to VScan Air; both vastly prefer their respective new probes.)

Butterfly iQ3 is the most feature rich and the most competitively priced. GE VScan Air is slightly more expensive but does not require an optional personal subscription†; it is also considered the highest resolution of the three models, by a small margin.

Features of all Models

Models reviewed below have several industry-standard features to be aware of:

  • Drop-proof. (Tested from 4 feet)
  • Relatively submersible / water proof (even in disinfectant). See specifics for each model below.
  • Battery life is generally sufficient for use all-shift. (Several hours of continuous scanning.)
  • 3 year warranty is industry standard, which realistically will be the life expectancy of a handheld probe during this era of rapid ultrasound advancement. See discussion below.
  • Compatible with both apple & android devices, (note: not all models are compatible; check with manufacturer.

Probe Lifespan Considerations

Learn more...
Given the rapid evolution of hand-held ultrasound technology, it is very reasonable to assume a 3 year lifespan for these devices. While most will continue to work for many years beyond, the technological advantage of upgrading per one to two releases is massive. It is wise to consider what the lifespan of a new probe will be, when considering whether to purchase a lifetime subscription vs annual renewals (if applicable). 'Lifetime' subscription typically applies to the lifespan of the probe, not the lifespan of the practitioner.

Wired vs Wireless?

Learn more...
The debate is ongoing.

Wired devices are tethered to their phone or tablet (albeit a long tether), however their boot-up speed is generally very fast (3-5s).

Wireless devices tend to have a much longer connection time (15-45s on average), which can prove annoying when working in a high tempo environment, if one isn't continuously scanning and wants to preserve the probe's battery life.

Bottom line: there is no clear winner in the wired vs wireless debate at this time. It comes down to user preference and isn't usually a detail worth agonizing over.

Butterfly iQ3

(Real World Report Card)
butterflynetwork.com/iq3
Probe Overview ✅ Three in One (Curvilinear, Linear, Phased)
Silicon-on-Chip (P4.3): All-in-one transducer replacing legacy crystals with thousands of micro-sensors, allows Butterfly to exceed physics limitations of conventional pizoelectric crystals. (e.g. BiPlane imaging allowing for visualiztion of a needle in short and long axis simultanously.)
Released February 2024
Base Cost (Hardware) $3,899 USD / $5,299 CAD (fixed MSRP pricing)
Optional Software Fees While optional, the subscription is required to unlock the full feature set (required to get the most out of fellowship level ultrasound.) Probe is still usable without a subscription.
Individual Pro: $420 USD / $600 CAD per year
Lifetime Membership†: $1,500 USD / $2,100 CAD
Note:Fellows receive complimentary access to the RUF educational subscription for a Butterfly probe.
†See lifespan discussion
Submersion Rating (water or disinfectant) IPX7: Rated for temporary immersion up to 1 meter for up to 30 minutes ("X" means it was not explicitly rated for particulate/dust ingress testing). Probe head and handle assembly can be submerged into an approved disinfection bath, but the cable connector must remain completely dry
What we love Drastically improved B-mode over previous generation (iQ+), making it comparable to other probes in the handheld-probe class. Regular software updates unlocking new features. Industry leader in feature set. Great battery life. Reliable. Excellent customer service from Butterfly itself. Generally a "no questions asked" return policy (while under valid warranty.)
What we dislike Cardiac resolution still trails behind Clarius HD3-PAL and GE VScan Air. Poor customer service through Trudell (the 3rd party distrubutor in Canada), with shockingly long delays in replying to prospecitve puchasers.

Like Sonosite, the design philosophylimit user customizability and granular control with limited presets. We wish that fine control of parameters like frequency, dynamic range, nyquist limit etc was optionally available for advanced users. This is a common issue with handheld probes in general, and not unique to Butterfly.
Wired / Wireless? Wired with approximately 2m cord. Ships with both USB-C & Lightning cables for maximum compatibility. Benefit to wired devices is much faster boot times and no unexpected disconnects.
Company Profile 🇺🇸 US-based (MA). Pure handheld-ultrasound pioneer since 2015. Reportedly investing more ($37M USD in 2026) in R&D than their competitors combined.
Next Model Rumours? "iQ4" expected late 2026/early 2027. A major leap in resolution is anticipated, with cardiac performance catching up to cart-based machines.
Butterfly is expected to release an "ecosystem" (app store) connecting probe users with 3rd party apps with even more advanced features. (Cardiac window optimization, auto capture and analysis etc.)

What our fellows say about the iQ3...
Good for : msk, soft tissue, adult lung, ocular; Ok for: pediatric lung, gallbladder, aorta; Worst at: cardiac

In reference to the Canadian distributor (Trudell Healthcare Solution): They have hit and miss customer service.

The resolution of this probe, at this price-point can't be beat. Is it as good as a cart based machine? No. No portable probe ever will be, but it's just as good as the Clarius & VScan when you average it out across all the indications we use this for in rural medicine.

Clarius HD3-PAL

(Real World Report Card)
clarius.com/pal-dual-array-ultrasound/
Probe Overview ✅ Two in One (Phased, Linear) - uses phased for deep abdominal/curvilinear needs with reasonable efficacy
Dual-Array Piezoelectric: Combines a dedicated Phased Array (1-5 MHz) and Linear Array (4-15 MHz) on a single wireless head.
Released Late 2023 / Early 2024
Base Cost (Hardware) $5,395 USD / $7,125 CAD (Fixed Canadian MSRP)
Optional Software Fees Probe does not require an active Membership to function but you get access to ...the Clarus Cloud exam Management Platform, AI software, Advanced Imaging Modes (Pulsed Wave Doppler, Needle Enhance, etc.), and the Clarius Education offering that provides tailored training to improve your ultrasound skills, just to name a few.
(See clarius page for full details.)

Clarius Membership: $595 USD / $785 CAD per year
One-Time Purchase: is available to RUF fellows. Contact us to learn more.
Submersion Rating (water or disinfectant) IP67: Rated for temporary immersion in liquid up to 1 meter depth for a maximum of 30 minutes.
What we love Voice control of depth, gain and clip capture is very handy, and a unique feature of Clarius. Good (in-class) resolution and primary PoCUS modes (M-mode, colour doppler, pulsed wave doppler), etc.

AI features and tutorials may be helpful for practitoners trying to teach themselves, but of no significant value for fellows.
What we dislike The linear array is off-centre from the middle of the probehead which is awkward at first, but easy to work with over time.

The probe gets very hot even with the accessory fan. The fan is described by one fellow as distractingly noisy and flimsy in construction; they are frightened they may accidently break a wire putting it on/off. Battery life is also inferior to the other models in the class. Customer service is mediocre and enforces timelimits (e.g. 30 day return window) very strictly which may be a consideration for prospective purchasers in rural/remote locations.
Wired / Wireless? Wireless. Nothing to get tangled in, however drawback is inconvenient connection times averaging 15-45s, and occaisional disconnects while scanning.
Company Profile 🇨🇦 Founded by the pioneers of the first handheld ultrasound (Ultrasonix). They focus on premium, crystal-based imaging for clinicians who find chip-based resolution insufficient. Often considered to be the makers of premium handheld probes
Next Model Rumours? Incremental software updates ("HD4" platform) focused on AI-automation (Auto-presets) and further battery optimization expected through 2026.

What our fellows say about the HD3-PAL...
Self-described Clarius-lover: I think Clarius missed the mark on the PAL creating a worst of both worlds instead of the best of both worlds. The advantage of a small footprint probe is it has a small footprint. If you glom on a linear array then you have defeated the purpose of a small footprint probe. I don't see the value in the Clarius PAL over the Butterfly or the VScan.

I don't want to brush a broad stroke over Clarius as a whole, my comments only pertain to the PAL probe: I can't compare apples and apples given I previously owned the original IQ, but have to say up to now I have been less than impressed with the clarius PAL. It has really good surface resolution, but lining up the needle is odd given its off centre on the probe, and the Phased array portion is also off centre making it unintuitive rotating 90 deg on the axis of imaging. The intercostal windows also are somewhat trickier as in some positions, notably AP3C view, the footprint has to be oddly placed on the ribs, and if you're scanning in basic cardiac rather than advanced cardiac, the probe orientation is flipped leading to the footprint being clunky. Also got a few patient complaints of 'sharp edges' especially in intercostal views. Not very satisfied up to now, but only have 3 weeks worth of scanning.

Clarius auto-updating without prompt in the middle of a scan: Happened twice last night. Middle of a cardiac scan, and shoulder. Couldn't go around it. It said - 'to continue using, mandatory update required: Update now or Turn off'. So update. Took near 20 mins. 5 reboots. Twice. Lost all the recordings I had done up to that point too. Frustrating fail of technology that I don't recall happened with butterfly with my previous probe.

I have to say this is one feature of Clarius I really appreciate, and the more I use it the more I like it: Voice Commands.

So far I'd say I haven't had major issues with the connectivity. There are lots of options for file transfer. I'm on android and PC and it seems fairly easy to move files around. In comparison to the GE vscan I feel like the resolution for abdominal studies isn't great but scanning using the linear probe and cardiac scans look pretty good.

To be direct, I regret purchasing this probe. It does not excel in any area. While it is acceptable for shallow work using the linear probe, the resolution is still not ideal. It also performs acceptably for cardiac views. However, in my opinion, the resolution for abdominal imaging is unacceptable. I would not feel confident diagnosing mild or moderate hydroceles with this probe. Pelvic structures and liver architecture are often barely perceptible. The images are consistently noisy.

I contacted Clarius about these issues last week, and they declined to accept a return. They offered a one-on-one session with a representative to discuss image optimization and a small discount on their curvilinear probe to supplement the PAL. I completed the session with the representative, and after adjusting all the settings and toggling AI features, he acknowledged, 'yeah, I can definitely see what you are talking about.' This was quite disappointing.

I have to say this is one feature of Clarius I really appreciate, and the more I use it the more I like it: Voice Commands.

GE VScan Air

(Real World Report Card)
www.gehealthcare.ca/en-ca/products/ultrasound/handheld-ultrasound/vscan-air-sl
A word about VScan Air CL vs SL versions:

Fellows generally report they prefer the SL probe (pictured below) for its small footprint, which makes transthoracic echo imaging much easier. The SL still offers excellent abdominal imaging.

Probe Overview ✅ Two in One (Phased, Linear)
Dual array probe. SL model is pictured.
Released Vscan Air CL (2021) / Vscan Air SL (Late 2023)
Base Cost (Hardware) $4,500 USD /$6,600 CAD (Fixed MSRP)
Optional Software Fees Digital Tools: ~$250 USD /$350 CAD per year.
Unlike subscriptions for other compaines, the VScan optional tools are typically unnecessary for personal probe use. Fellows report exporting clips from the local device is easy, thus the cloud storage, collaboration & remote management are not typically necessary for single users.
Submersion Rating (water or disinfectant) IP67: Rated for temporary immersion in liquid up to 1 meter depth for a maximum of 30 minutes.
What we love Generally VScan has the best resolution of all the current personal-probe class. (By a small margin.)
Works forever without a subscription.
What we dislike Less software bells and whistles than the other models, though VScan has all the important core features one would want at the fellowship level.

VSCan records clips prospectively, as compared to the retrospective default of most probes. This isn't really a dislike (it's actually a better method), but may take a short time to get used to.
Wired / Wireless? Wireless. Nothing to get tangled in, however drawback is inconvenient connection times averaging 20s, and occaisional disconnects while scanning.
Company Profile 🇺🇸 GE HealthCare is the grandfather of POCUS, and a giant in ultrasound techonology, period. Unlike the other companies, they not only build cart-based PoCUS machines, but arguably some of the best cart-based machines. GE has massive legacy infrastructure and reliable global support. The Vscan line effectively defined the handheld market in 2010.
Next Model Rumours? Major focus on Caption AI integration (auto-guidance) through 2026. A "Vscan Air 2" with improved battery is speculated for 2027.

What our fellows say about the VScan Air...
Boot time?
  • VScan takes usually ~ 20 sec to connect to my phone.
  • Boot time is a good 30-45sec, fails sometimes and requires redo, once connected I have not had a crash. I keep it logged in and on its loading bay during a shift to save on connection time (that helps me a lot)


Compatibility?
  • No idea about android, I have apple products and videos airdrop easily.


For a pocket probe I've been quite happy with the Vscan. Imaging quality is pretty good for an all in one. Videos are easily airdropped from phone and can be uploaded without modification. Yes it has PWD and colour doppler. My only minor complaints about the Vscan are it doesn't have CPD or tissue Doppler and I think they could improve upon their calculation suite. For example there is no way to do VTI or an option to convert fetal length to weeks & days. These are options that seem like they'd be easy to add, but not a deal breaker for me as I don't make these measurements frequently.

On prospective-only recording: you cannot record the next few seconds, only the preceding few seconds. It was annoying at first and hard to get used to but now I like being able to save clips you saw in the past, you get used to it.

CL vs SL version?
  • I would recommend the SL. The sector probe performs well in the abdomen but the curve linear probe is not great for cardiac. Perfect world you'd have both, but for one id go SL.
  • I started with the CL, ended up leaving /selling that one and bought the SL. Strongly prefer the SL for cardiac views and good enough for abdo and pelvis. I bring my SL on OB shifts and it is great for that too. I'm really happy with it.
  • I haven't tried the SL, but I found the CL wasn't ideal for cardiac, but was good enough for the cardiac views I want in the office.

Mindray TE-Air e5M

(Evaluating...)
www.mindray.com/na/products/ultrasound/portable-ultrasound-machines/handheld-ultrasound/te-air-e5m-handheld-ultrasound/
This probe, released in March 2026 in Canada is new to us.

So far our inquires and loaner-request have gone unanswered by Mindray. With several future fellows enrolled, we hope to be able to update this section with our own real-world data soon.

Probe Overview ✅ All-in-One Virtual Array (Linear, Convex, Phased)
Single-crystal probe with software manipulation to cover up to 22 different exam types.
Released Mid-2023
Base Cost (Hardware) $4,500 USD (Fixed MSRP)
Optional Software Fees None. Mindray explicitly ships this with no subscription models or hidden cloud fees. The companion app, firmware updates, and core advanced calculation toolsets are entirely free. Your data is owned by you and saved locally or pushed directly over DICOM.
Submersion Rating (water or disinfectant) IP68: Officially rated for continuous full immersion.
What we love ... gathering experience ...
What we dislike ... gathering experience ...
It seems battery life may be a factor, limiting use to 60-120 mins between charges. An optional Air Capsule (charge-case) listed for $750 USD may be the work around.
Wired / Wireless? Wireless. See note about industry-wide wireless connection lag time & disconnects.
Company Profile 🇨🇳 Mindray is an international heavyweight in medical electronics and cart-based diagnostic ultrasound (highly respected for their TE and Resona cart systems). They entered the handheld POCUS space later than GE but brought over advanced, cart-grade signal processing architecture, offering highly robust software calculations natively on mobile screens.
Next Model Rumours? Rumors point to a split-footprint dual-headed iteration or an extended-battery life chassis slated for late 2027.
