The all round target soon became useful as reference points and setting out datums in all kinds of construction work. Sentripods Inventor was also an experience freelance setting out Engineer with an Open University degree in Systems design. The MB270 is the same as the Railway version but for the bulldog railclip.
Because of its lightweight portability it can be readily fixed to most surfaces using a cartridge “Grabtite” adhesive. This holds straight away and sets hard .
More Engineers now prefer it in monitoring listed buildings and resection control as in Bath City Centre and Manchester Metro project currently. At home and abroad BAE Systems use Sentripod in marine architecture and in extremes of Australian sunlight and underground dark conditions. Cities, Eurotunnel, Hydro Dams in Wales, Gold mines in South Africa, Kiln monitors in industry, Foresensic surveying in U.S.A. and nuclear installations at home.
On construction sites, several of the Sentripods can be mounted in safe,
easily visible locations, such as buildings opposite the site, or lamp
columns or anywhere stable around site. This eliminates the need for
heavy, bulky uni-directional prisms, as you can set up ANYWHERE on site
using resection/ free station, as the Sentripods are visible from any angle.
Sticky, retro targets limit your possibilities since they are only accurate
when observed within 30 degrees from its perpendicular. And they cannot be
“I have 4 Sentripods on the site I’m working on currently. I use a Leica
TC705, and all my resections produce residuals within 1mm, in all 3
directions. No prisms and tripods to carry around that get knocked over,
simply set up where convenient and do a resection, as easy as that! My dumpy
level is under the desk, gathering dust, because with such excellent
resected set-ups, I use the instrument for height as well.
And the best thing is, when I go to the next job, the Sentripods come with
me! For a price less than the cheapest mini-prism, you’ll wonder how you ever
did without them…!”
