Question & Answers
This is a brand new Topcon RL-H4C Laser
Slope matching feature allows for easy grade setting using two arrow buttons. Simply press a button to start tilting the laser, and press it once again when the sensor receives laser on grade.���
No it does not. This unit uses regular flashlight type D batteries. Case has room to carry spares. The laser uses two D batteries and the target uses 9 volt block type battery.
Think about how a day is divided into hours, minutes, and seconds, an angle (of elevation in this case) can divided into degrees, minutes, and seconds. A (arc) minute is 1/60th of a degree, and a (arc) second is 1/60th of a minute, or 1/3600 of a degree. Using some trigonometry, one can calculate the amount of rise or fall "error" that 10 arc minutes would lead to. At 100 feet, 10 arc seconds corresponds to a bit under 1/16 of an inch of potential elevation error - VERY GOOD. If you are building something that requires better accuracy than that, such as the Large Hadron Collider, then maybe this product isn't for you, but otherwise I think you are quite safe. Surveying is an area where technology has truly improved life. I have an older model Topcon (less distance, and lower accuracy) and I absolutely love it. Answer submitted by a confirmed purchaser

30 year contractor up dating a 1998 Topcon unit.
Great level, great price!
the lasor is real easy to use. built to last ive dropped this thing so many times i cant believe its still accurate. decent battery life when running on batteries. not too pricey when you consider the quality you get.
I've been in the grading and pipeline business for 25 years. Topcon transits have always been my favorite. This is the first rotary laser I've purchased. I've only used it on one job so far.it preformed flawlessly. Have not used the slope matching feature or machine mounted receiver yet. Purchased the machine mounted receiver separately. Will update after I use the other features.
