I have used Hilti gear for over 30 years,and it knocks most in to a cocked hat. Even though over that time,they have obviously outsourced some parts,their QC,and specification remain excellent. They have good product back up,and are not going to disappear. The battery technology,in terms of power,charging and longevity,has come on massively,and my recently purchased 15V SFH drill,has at LEAST the grunt of the 22V model ten years back. I own a fair bit of Hilti tackle,and looked after,it is second to none. I bought a little self-set laser level 20 years ago (PM10) and have used it to set out some quite large projects,as in footings,floors and drainage. I usually do a back-set check to ensure accuracy,which is where you transfer a level from where the device is,to a point elsewhere. You then move to that point,and transfer the level to where you started. You then have two marks in one place,and two at the other,you measure between the marks at one,then the other,and the difference between the measurements is your back sight error. Over 30 meters,that difference was 5mm! Now i have waffled enough,get one bought,and listen to your colleagues scoff at the cost,as you observe them renewing their kit,several times,during the life of yours. :icon12:
