Hi Guys
I'm planning to buy a robotic total station to start doing jobs on my own!
I'm doing boundary surveys and construction layout.
Can I get thru with a 5" angular accuracy instrument?
Thanks
Yup

Yes
Keep in mind that there is a world of difference between a 5" gun and a 3" gun in terms of repeatability in the long run at reaching out farther with shots.
Maybe it is in the quality control when made or tighter specs in the alignment.

Your main consideration is probably what type of construction layout you do. If you are doing precise work, go with the most precise and best quality instrument you can afford. If you are doing typical site work stakeout (residential subs, retail & light industrial developments), a 5" gun is just fine. Remember that it was only just over 30 years ago that many of us were still doing that sort of work with a 30" transit and steel tape as standard equipment.
Calc it out! What is your error in 100' and what is you error in 300'? Then strech it out to 1000'. I think you'll find a 5 second is more than capable. Spend your money elsewhere, like a good bubble in your prism pole or other assesories.
I sell more 5sec instruments than all the other angular acuracys combined.
I always use a 5 second. I literally just got a new machine today that is a 3 second but that is because it is a refurbished demo unit and I had no choice
Our DOT requires min 3" gun, so that is what I bought. (we used to use a 1" gun for everything.)
Look at your potential jobs, and see what you need.

Me too, been using 7" guns for years.
[sarcasm]I bought a one second instrument, but it still takes five seconds to take a shot. I think I got ripped off...[/sarcasm]
