Topcon RL-H4C and Topcon Taurus 2LS

February 22, 2016 / no comments, on Reviews

The Topcon RL-H4C rotating laser is one of the most popular lasers levels of its type sold around the world, why?

Well first and foremost Topcon as a brand has had a reputation for many years for reliability and durability.  This was largely built on the back of the RL-H4C’s predecessor the RL-H3C.  The 3C was build predominantly in Japan and was simple to use and pretty much bullet proof.  It was the go to laser for simple site levelling such as concreting.  It was so well regarded that after a coupe of years of being superseded it was brought back into production as the Taurus 2L and a good buy for those just requiring general levelling and durability, concreter’s ideal laser.


Back to the Topcon RL-H4C, features wise the 4C is electronic auto levelling, works in the horizontal plain only, has single grade slope setting (see note below) and operates on Standard cell batteries (again see note below)  Accuracy is similar to competitors, although they use arc seconds which means nothing to the average builder (most use a tolerance rating of mm over 20 or 30m) but when you convert it is compatible or slightly better to many other brands.  Range is also similar to competitors maybe a little greater and comes with a reasonably standard receiver. Core specs below.

  • Accuracy – 10 arc Seconds (approx 1mm over 20m)
  • Range – 800m diam (up to)
  • Laser Type – Class 3r (class 3a)

Two things to keep in mind when purchasing the Topcon RL-H4C is that it is sold either with rechargeable batteries and charger or without, so make sure when you buy that you get the package you want.  Batteries and charger can be purchased later but they cost a fair amount.  The other thing to keep in mind is the inclusion of a grade/slope feature, now again on a marketing feature list comparing against competitors without a grade feature it looks great, but the reality is that to set a grade is not easy and requires two people.  If you want a laser to set grade on a day in and day out bases then this laser is probably not for you.  If you generally just set level and only very occasionally could do with grade setting capability then go for it.

So in Conclusion the Topcon RL-H4C is a great basic self levelling rotating laser, but, its not the only great laser out on the market others worth checking out are the Leica Rugby range, Hilti,  Spectra, plus more.
