A&D Medical Lifesource UC-324 ANT+ enabled Weight Scale Review


I’ve reviewed a number of scales in the past, but only two of those are still used within the household on a daily basis.  I say two, simply because one is in one bathroom, and the other in the other bathroom.  Yet, I still have a fairly significant pile of other scales (both connected and old-school).

The first scale you know of is the Withings WiFi Scale, which I’ve been using forever.  But the second scale, one I’ve only occasionally mentioned, I’ve been using it since I bought it last September.  Oddly enough though, I just never got around to writing up a product review on it.  Time to change that!

The scale is officially known as the A&D Medical Lifesource UC-324 ANT+ eHealth Wireless Precision Scale.  But, we’re just going to call it the Lifesource scale, because that’s a heck of a lot easier.  Of course, A&D makes a few different variants of this scale – in both ANT+ and private wireless version (not WiFi), but I haven’t played with the non-ANT+ version – only the ANT+ version.

Like all my reviews, they tend to be pretty in depth (perhaps overly so) – but that’s just my trademark DC Rainmaker way of doing things. Think of them more like reference guides than quick and easy summaries. I try and cover every conceivable thing you might do with the device and then poke at it a bit more. My goal is to leave no stone unturned – both the good and the bad.

Lastly, at the end of the day keep in mind I’m just like any other regular triathlete out there. I write these reviews because I’m inherently a curious person with a technology background (my day job), and thus I try and be as complete as I can. But, if I’ve missed something or if you spot something that doesn’t quite jive – just let me know and I’ll be happy to get it all sorted out. Also, because the technology world constantly changes, I try and go back and update these reviews as new features and functionality are added – or if bugs are fixed.

With that, let’s get into the unboxing!


You know what I like about scales?  They really don’t have many parts.  And thus, I won’t belabor this particular section anymore than I normally belabor unboxing sections.  The unit comes in a box roughly the size of a deep dish pizza box (oddly ironic):


Inside the box you’ll find precisely three things: The scale, some paper, and the AA batteries (Woot, it actually includes them!).


Only two of three of these items you’ll actually need though.  The third you can utilize for building paper airplanes.  Since it’s a book with a bunch of pages, you’ll actually get a number of paper airplanes out of it.  A small fleet really.

(Potential Paper Airplane Material)

With that, you’ve successfully unboxed the scale.  Yup, it’s that simple.  Let’s get into setup.


Once you’ve got the scale removed from the box, you’ll simply go ahead and flip it over.  At this point, you’ll see the little ID tag on the back with the model information.


Below the model information is a small not-so-secret compartment where you’ll stash the four AA batteries used to power it.  It’s now March – some 6-7 months after I first put those batteries in, and they still work just fine for me.


With that, you’ll go ahead and clip the cover back in place and flip the unit over.  When you do so you’ll notice that there’s a small button-looking thing on the front, you can see it below:


Ignore this button-looking thing.  It does nothing.

Instead, flip it back over and look at the back of the unit near the top and you’ll see a single button.  This button has merely one purpose in life: Switching between pounds or kilograms.  That’s it.


Once you press it a few times, it’ll change the mode between the two measuring systems.


Beyond that, there are no further configuration items. Because the scale doesn’t measure body fat (just weight), there’s really no need for additional information like height or age.

Connectivity via Garmin watches:

If you’re forking out roughly a $100 for this scale, there’s likely only one reason: Because it integrates with your Garmin Forerunner watch or Edge 800 bike computer.  Of course, it also integrates with a few other devices, which I’ll talk about later – but the primary one is really the Garmin Forerunners.

Within the Garmin series, most of the more recent watches include support for connecting to the scale wirelessly via ANT+, including the FR610, FR310XT, FR910XT, FR210, and the Edge 800.  It does not support the older FR305, FR405 or even the newer FR410 however.

Pairing with the scale happens wirelessly, and is pretty straight forward.  Unlike some models such as the Tanita scales, the order for the Lifesource scales is actually different in that you weigh in first, then the Garmin will receive the data.


To wake up the scale you’ll simply lightly kick it.  Note, the manual says ‘tap it’, but really, I’ve found kicking it more effective.  Though, technically the manual also says not to ‘kick it’


The manual also includes reference to avoiding exposure to “strong external noises”.  I feel I should point out that if you’ve ever been around the bathroom after some good refried beans – I’m pretty sure that would qualify as ‘strong external noises’.

Moving on…

The scale will take about 3-5 seconds to go through an auto-zero procedure.  This ensures that you get accurate data each time by zeroing the scale.  It’s ideal at this point to not place any objects (including yourself or small animals) on the scale, otherwise it’ll impact the accuracy.

Once done, it’ll beep and you can go ahead and stand on the scale.  About 2-4 seconds later, it’ll have correctly recorded your weight.


Now to get the weight into your Garmin!  To do so you’ll trigger the weight scale search routine on your watch.  It varies by watch model, but typically it’s done by pressing the power button lightly once.  Note that if you want you can usually start this just after you wake up the scale.  Once the watch starts looking, it’ll look just like this:


If you’ve already weighed in, it’ll find it pretty quickly – and immediately report back your weight:


Because the watch is somewhat expecting more information (such as body fat and hydration), it ends to keep displaying ‘Receiving’ for a bit (like above) – but no worries, the data is already recorded.  Once it decides the scale isn’t going to present any more information, it’ll look like the below.


Additionally, if somehow during the process your timing gets off, it’ll show a small error message.  Simply start the process over again.  But really, this very rarely happens – especially once you’ve done it a few times.


With that, the measurement is recorded to the watch.  Note that if you take your weight measurement while the watch is not around, it will NOT store the value for later uploading.  It simply displays it and then forgets it.  While I do wish it would record it for later, in many ways, the primary reason I prefer this over the Tanita scales is that it simply shows me my weight.  I want an LCD, and I want to see my weight – even if my watch isn’t handy, and even if I don’t want it recorded somewhere.

Garmin Connect data display:

Once you’ve taken your measurement, it’s time to go ahead and upload it to Garmin Connect (Garmin’s free online site).  This will happen automatically when you use the ANT Agent to wirelessly upload your data.  In watches where the ANT Agent isn’t used (i.e. the FR210 or the Edge 800), the data will be embedded into an activity file, which gets uploaded automatically.

The data will appear on Garmin Connect in the Health area/section, which is essentially a digital locker for health data.  Because the Lifesource scale only records weight – you’re really not going to get too much out of all the features and data fields that are normally displayed here, beyond just simple weight:


You do get a small graph which can show your weight changes over time though – in the event you’re looking to track weight trending over a longer period of time.


Also, Garmin Connect did implement the ability to both delete and manually enter a given weight, which is handy when a non-valid value gets in there somehow (not typically a scale issue, but very rarely a Garmin data point recording issue).

Note that at this time, neither Training Peaks nor Sport Tracks support the ANT+ scales (including this Lifesource one), and in fact, I’m not really aware of any other sites that consume the files either.

iPhone & Android Support:

In addition to native Garmin watch support, you can also utilize an iPhone with the Wahoo Fitness dongle to connect to the scale.  Though, getting the data to anywhere is dependent on the application you use, but it’s certainly an option.

Further, for those with ANT+ enabled phones (like the Xperia Active), you can use those phones to connect to the weight scale, though, applications to do so are super slim pickins.  Basically just the test app to my knowledge.

There isn’t any method (to my knowledge) to connect to the scale using either a Blackberry or Windows Phone due to the lack of ANT+ support on either of those two platforms.  Further, the Garmin Fit iPhone Adapter doesn’t really provide any value here either, since it won’t connect to the scale.

ANT+ Scale Options:


There are essentially three major ANT+ scales on the market today (and a handful of derivatives of these scales).  All of these connect to Garmin devices (note, they do not connect at this time to any Timex ANT+ devices).


I’ve previously reviewed the Tanita BC-1000 Weight/Body Fat ANT+ enabled scale, and though I haven’t reviewed the Tanita HD-351 (but do own it), it’s also in the market.

The challenge is that the Tanita HD-351 is between $40-$50 more than the Lifesource scale – but with less functionality.  Since it doesn’t have an LCD screen, you always have to have your watch nearby if you want to find out how much you weigh.

In many ways, that’s the primary reason I’ve largely stopped using the more expensive BC-1000 day to day.  I simply don’t always have a watch nearby, or don’t feel like turning it on/off.  Now, if you’re looking for body fat and hydration, then really, the BC-1000 or the newfangled crazy expensive Tanita BC-1500 is the way to go.

But, note that as I’ve pointed out previously in my BodPod testing series – body fat is a fairly imperfect science.  On the flip side, all of the weight scales were spot-on with calibrated weights when it came to simple weight measurement.  Meaning, more expensive simply didn’t mean anything.


The core benefit to this scale over a cheap $20 one from Target really comes down to tracking and measurement.  The scale will assist you in recording that data – either for informational purposes, or because you have a goal weight in mind.  It won’t of course lose the weight for you, but as is usually the case, simply recording the weight tends to help folks reach their goals.

When looking at the scale price-wise, it’s the cheapest ANT+ scale on the market today.  But it’s also priced just below (depending on how much you pay for it) the $160 Withings WiFi Scale, which is one of my all-time favorites – simply due to the broad integration with tons of companies and sports partners.

So who is this scale for?  Well, mostly the individual that wants to have weight data automatically entered into Garmin Connect for them, and wants a mid-priced option to do so.  Well, really, there aren’t any cheap options – so technically this makes this the cheap option.  The expensive options range into the $500 arena.

  1. Thanks again for such a detailed review!

    Does the garmin 500 support ant+ scales as well?

  2. The most fun you can have with a weighing scale is to stand closely behind when your wife or girlfriend is about to step on it, then gently and secretly putting your toe on the scales with just enough downward pressure to add a couple of pounds to her readings.

    Then watch her reaction. Hours of fun.

    I’m disappointed that you missed those obvious usages in your apparently in-depth review. ;-)

  3. Hi Ray nice review. As a fellow engineer I request that you should be slightly more particular about what it is actually displaying. Yes it is measuring your weight, but it’s displaying a calculation of your mass, which is what the garmin is recording ;)

  4. Walking into your bathroom is enough to make some think you have a serious weight issue.

  5. Do you do anything to offset your carbon footprint? Buy credits, etc.? My husband and I travel a lot and we buy gadgets from time to time too…we have been thinking a lot about our contribution a lot lately in light of the current warming trend. Just curious.

  6. Your weight-versus time plot is a good example of why people shouldn’t obsess over single scale readings, and why short-term weight loss and gain has little significance. The “noise” is several lb in each direction of the trend.

    It would be interesting to see continuous data over the course of a week: samples every minute or so. Maybe build pressure sensors into the soles of your shoes :).

  7. Thanks for the review. Do you know if it works with the Garmin FR70?

  8. Bruce Mac

    Love the reviews Ray – keep them coming! (I’ve purchased the Garmin FR610, FR60 and Edge 800 based on them) I’m stilling waiting for a product more like the BC-1000, with all the data coming down to Garmin connect, but with a simple display screen on the scale (maybe with an “toe option” Y/N to transmit, in ANT+, to watch or Garmin connect, etc.)

    Hi Ray:

    Reviving an old post, but I got this scale to use with my FR 610 watch and I am having a really hard time to get it to sync the readings reliably and accurately.

    First, I can only get it to sync properly one out of every 4 or 5 tries. Second, when it syncs, it’s always .3 pounds higher on the watch than on the scale.

    Any tips for proper syncing? Do you usually “wake up” the watch before stepping on the scale? Or is a simple push of the light button enough to get it to sync?

  10. Hi Pat-

    Have you updated your FR610’s firmware? I know there was an issue with some of the earlier firmware builds where the connection was being funky to the scale, but that was fixed – I believe in the June 2011 update.

    As for differences with weight – no, definitely not normal. I haven’t seen that on any of the ANT+ scales ever. Very odd. I’d ring up Garmin support first if a firmware update doesn’t cure it.

  11. Pat

    Just an update. Yes, I had the latest firmware. What I’ve found out:

    I really need to “unlock” the watch before stepping on the scale. If it’s lock, it barely ever works. If the watch is unlocked, it works fine, and pretty much instantly.

    As for reading 0.3 pounds higher, I have no idea. Since it’s consistent, it’s not such a big deal and I can live with it.

  12. All of my Garmin readings are also 0.3 lbs higher than the readings on the scale.

  13. Anonymous

    I’m delighted to know that there’s a cheap ANT+ scale. Like the last commenter, I’d like to know if it works with my Edge 500. Any idea?

  14. Hi Ray,

    I’d like to buy this scale but I only find it on American website. For instance, do you know where I can find it to be delivered in France?
    Thanks for your help.

    BTW, as a French reader, I’m delighted by your post about your life in Paris :)

  15. Alessandro Vivas Andrade

    Hi, I would like to know which is the best scale: Tanita bc-1000 or withings wifi body scale? I need choose only one. I had a garmin 310 XT but I need more than simple weight. I need a scale with fat and other measures. Other point is the accuracy. Thanks

    • DC Rainmaker

      I’d go with the Withings Scale, between those two.

      However, as per my accuracy tests – neither scale is good at body fat testing.

  16. Steve Knapp

    Is the surface of this scale glass? Looks to be.

    I know folks who take the HD-362F with them to workouts to measure weight before/after. Would be fantastic for something to be that size and durable yet have some way to push to TP.

  17. 6co

    Hello Ray
    I love your website, it’s fantastic. Thanks for sharing all of this. I spend so much time browsing it and reading stuff, that I can’t help thinking how much more time of yours you need to write and post it all up. Congratulations!
    Just a little comment if you did not know. There is now a plug-in for Sportracks that will pick up the weight out of a Tanita BC-601scale, through the use of an SD card.
    I think the process itself is pretty neat: just upload to your PC once in a while when you feel like it, but always be recording it, I am not too happy about the fat %age accuracy of this scale, but I love the process!
    Again thanks for your website, those gadgets are motivating you would not believe! If I dont have my FR610 for a run, I turn around and go home!!
    By the way, I am French and although I live now in Central Africa, I have spent my childhood and studenthood in Paris, and I do enjoy all your parisian posts, seeing your training routes in Paris etc..
    Take care!

    Hi Ray, Nice work you do here, thanks!
    As it relates to Samsung S Health and my Note3, do you think this Ant+ scale or the 321PBT-C blue tooth scale is a better choice? Wouldn’t the phone have to be right near the scale for it to read the ANT signal? And wouldn’t it read up to 30 feet away with the blutooth signal? Your advise here would be appreciated.
    Also, why can’t I find the Samsung scale anywhere but in UK?

    • Honestly…neither.

      I’d really look at other services like the Withings or Fitbit scales these days. Just so much cleaner, better tied in, with apps, etc…

      If you really wanted to go with ANT+ or BLE, I’d go ANT+ in this case since it’s just slightly more open.

  19. DC, I always enjoy your reviews and appreciate the time and effort you put in to deliver consistent quality. Based on your reviews I’ve purchased the Garmin 310XT (Love it), Specialized road bike ( really love it) and getting ready to buy one of the power meters based on your analysis. I’ll load up at Clever Training with your code.


    • Thanks, I appreciate it! Best of all is that right now the Garmin Vector has a $200 rebate, which you can combine with the 10% DCR VIP discount (10% taken pre-rebate). Pretty solid overall savings. Of course, Quarq and PowerTap are also available through Clever Training. Enjoy!
