Bosch GRL-500 Laser Review

Bosch GRL 500 HCK Review

There are many things that caught my eye the first time I took a look at this laser.  Before moving up to this rotary laser, I had the Bosch GRL-400 and I enjoyed using it but disliked that it took 4 normal batteries to run it.  This unit is powered by a lithium ion battery and the charge time is fast if it is left uncharged.  I also noticed right away that the remote would let you know if you were high or low on the receiver end and guide you to laser area.  That is a big deal when you are out past 1,200 feet and can hardly see the laser let alone get it within a 1/4 inch of grade to take a measurement.

Bosch_GRL_SecurityInitially, I overlooked the security feature thinking it might not work out as planned and wondered if it would really secure the unit. After having time to mess with it and do some testing, I firmly believe that this will alert you that the unit is being taken, but I am unsure if the people taking the rotary laser will be educated enough to understand the unit they just stole is unusable without the paired remote.  The only drawback to the security system that I see is possibly not being able to use multiple receivers with one rotary laser.  I am in process of finding more information on this.

Working with the dial a grade feature is very nice for many tasks. I started using it to complete some landscaping around my barn and I was impressed by how easy the unit was to set up and use. I had never used this type of feature before in a rotary laser and at first I feared it being a difficult task to set up and then to use. It made these tasks much easier for me as a non-professional excavator, if you could take it that far. Our professional friends have confirmed that this feature is something they are looking for in the field and it is easy for them to use.

Bosch_GRL_BackThe final part that I really like about this unit is the carry case.  When you have a large, expensive item, I want a good case that handles everything.  It would be nice if Bosch would incorporate a way to snap in the measuring stick to the case for travel in the back of a truck, but I do not believe that to be a necessary feature.  If you are in the market for a rotary laser, be sure to take a look at the GRL-500 as I think you will be impressed.
