All I’m thinking is ‘another battery to remember to charge’ 😂
That's exactly what I was thinking haha
Cool stuff man. Love your videos.
By the time you charge the AP20, fit it, connect it, initialise it and what have you small jobs would be completed using traditional methods. Great for bigger jobs or working near columns/walls etc. though for sure!
The accuracy isn't quite the same the other way around. For example, if you're staking out. In this example the tip of the pole is on a known point. The smarter solution is to have the prism lower on the rod (if your line of sight allows).
The Autopole is wicked expensive. Like more expensive than a good used total station.
Hi Rami, nicee news!! thanks to share the infos, nice product and pratical review.
Great Video, good Job. Next time try some building corners to see there the precision!
Great field test! I am thinking about buying this tool, especially for mapping jobs, the error for mapping is negligible. Not sure about construction staking or checking of f.e. formwork, surface checks (asphalt, concrete) where you have high needs for precision (6mm at max is critical in some situations).
I see that you are using CS30 controller, is there any chance, that you'll be doing a reviews for this particular tablet? I can't find any reviews. Thanks.
Very Nice tool
I really like that you use the leica hardware. We also use the exact same equipment. In my opinion the best instruments on the market.
Really appreciate your content. Keep up the great work. ❤
A little throw in… if you are measuring mm, i think it would be better to measure the reference with a shorter rod. Otherwise if your bubble is not calibrated there would be an error. An other method could be measuring the reference in 2 faces, to eliminate the error from the bubble.
@Alfred Hollis Yeah … some might say that. Not in my opinion :)
I used a TS16 for 5 years now with Captivate. I can use it, but everytime I take it out I hated life, lol. I was going to quit but then Trimble came back to me. Happy life.
Have you tested the ap20 with a tall fiberglass extension rod? Like 25' tall. Is there a height limitation or warning built into the software?
When can we get an auto measure at maximum height feature? That would be pretty slick I think. Put your rod on the point and the instrument will store the measurement as the prism passes through a maximum elevation
Si puedes ajustar a subtitulado al español. Sería de más impacto tu canal. Eso digo! Por lo otro muy buena información sobre el uso de esta herramienta en aplicacion a topografía.
That’s so helpful
What is the model name of this total station? 🙏🏼
Some of those errors probably exacerbated with randomised facing/orientation of the 360 prism. The angle of the tilt during the test was quite extreme, I’d like to think when actually using this you’d probably be closer to being plumb, it would be interesting to see if results are better or not when the IMU is compensating less
IMU's perform best when they are being moved a lot, if they are static then the relationship between the biases and movement they are trying to measure becomes too small and inaccurate measurement results.
You make a good point. The GRZ122 360 Prism is excellent, with an improved accuracy compared to the classic GRZ4 360, largely due to its smaller size. Despite that, errors in the 0.01’ range are not uncommon. I’d like to see the same test with a GRZ101 Mini 360 which has the best short accuracy of the three 360’s. With small size comes reduced tracking and power search capabilities. However the Autopole also helps mitigates tracking issues.
How do you keep the vines, briars, leaves, branches from bouncing off of it or from wrapping around it?
Very impressive results... I hope it doesn't cost the price of a sports car though...
Niiiiicccceeeee
Hello! Tell me the marking of the milestone that you have on the video
Hi,
I am structural engineer that does simple internal building surveys. Can you investigate if using the Leica Disto S910 will work the AP20 and or be integrated with any other technologies such as the video etc.
It is easy to stay focused while doing a dozen shots in a park setting in lovely weather. The advantages of the AP20 are not so evident in such use. Real world, a guy might be taking his 400th shot of the day on a busy noisy street on a blustery, wet day with all sort of things in the way. This is where that automatic correction, both for plumbness and rod height, is going to really save surveyor butt.
Seems like a game changer
Hello friend, I work as a surveyor in Belarus. Tell a friend which sites in the USA I should apply for to find a job as a surveyor, I worked only in geodetic support for construction along this profile, building houses, schools, kindergartens. Will they take me if I have a Belarusian diploma or do I need to retrain in the USA and where to go to retrain in the USA?
Cool tech. I'm assuming the ap20 needs to be tilt-calibrated every time it's powered on plus it needs to connect to the gun? That ought to be reflected in the time trial as well.
All you need to do to calibrate the tilt correction is swim it around a bit. You do need to keep moving or it will lose calibration, but it's easy to get it back.
@@markmayer5788 good to know, thanks! 🤘😎🤘
Wow
With which model it is compatible?
Hi Sir,
I'm be watching you for a while and you really help those who are in this industry a lot. Please, could help with a tutorial how to change Stake out offset. Its a task I'm still facing issue. Let say you have been given a certain number of point to stake out and at the job site because of some issue you have to change the position of the stake on the ground.
Thanks again
Are you using Carlson?
Very very nice
Does this autopole exist for Topcon robotic total station?
Not at the moment.
@@RamiTamimi Thanks a lot and a big Hi from Algeria
Can you please let me know Cost of AP20 in India
How tall are you?
I wonder if this will work with Geomax being a rebranded Leica hun
The software XPad must be updated to support the AP20, there is no update for now but I Know that fieldgenius will support AP20 in futur build.
Are people still loving these? Are they worth the pennys?
I wonder what is Trimbles answer to this AP20.
Trimble sleeps.
When it was the Sokkia RCP3 or whatever, it's was 'ridiculous' to have that big and heavy device on the top of the pole, then it came Leica with almost the same and it is "impressive"
Totally different gear. Much more features than prism search. Autoheight and IMU.
6mm? i can hold a rod to within 6mm of level almost instantly., not accurate enough garbo
Lets see how well it works after Leroy beats back brush and throws it in the truck bed for a year
Leroy must be a Topcon user.
@@markmayer5788 Leroy is from an outfit that hates their boss and doesn't understand he won't be kept around a nice place
Hello sir please reply my comment please
Who cares!!!! Topo surveys do not need this accuracy
I’d rather see it used in stakeout
Leica AP20 is all about the ability to measure points accurately with speed and tilted pole. Given the ability to tilt pole means that you can measure points that are inaccessible using plumbed poles. Of course, you can always use standard offset routines if speed is not an issue but is vulnerable to errrors. In a construction site, a lot of points are inaccessible using standard poles but can be measured with AP20 tilted poles. AP20 also promotes safety. Imagine surveying along highways with speeding cars and you can't tilted your pole and measurements are not quick enough. Leica AP20 is game changer in my opinion.
Very hard to follow you with the f... music on the background, for me it ruined all the hard work.
