This is a fantastic piece of kit. It provides an instrument for basic use but also has advance slope features, which are often only found on instruments twice its price. The sturdy housing also provides a very stable and reliable tool.
The instrument itself only has 1 button, an on and off switch. This will automatically give you a rotating laser beam with high accuracy. This is ideal for most uses and gives an accuracy of +/-3mm over 30m.
For the more advanced uses that require gradients then the remote control contains these facilities. This avoids confusing the basic user but also helps not to disturb the instrument with cold/wet/numb fingers. Gradients can be provided in two planes up to a maximum angle of 5 degrees (1:20) or 0.5m over 10m.
The set comes with rechargeable batteries and its own recharger but standard AA batteries can also be used. This combines the economy of rechargeable system but with the convenience of being able to stick a set of standard batteries in if you forget to recharge.
