It is true that the lasers can cause eye damage, but it depends on the class of the laser and how it is used. VH-80's lasers are classified under class II. This class uses lower power, making it safer. You will only have issues with your eyes when you stare directly into the source, and it's harmless to the skin.

We have met with many shipping companies to figure out the most reliable way to deliver VH-80 to our backers. The current shipping fee is a realistic estimate for delivering at the moment. It also includes handling and tariffs accordingly. We will be finalizing our choice of shipping partner towards the end of our campaign when we have a closer estimate to how many we'd need to send out. Stay tuned!

The key for a successful use of a laser distance measurer lies in the red dot. If you can see the laser pointer on your target object, it most likely means the LDM can as well. In general, opacity and reflectivity is key. Most ideal surfaces for to take a measurement are opaque and reflective (not black). This means transparent and light absorbing surfaces are hard for VH-80 to sensor.

Just like any other electrical component, it is likely to be affected by dust in terms of the hardware. If will help to give it an occasional spring cleaning. For the laser sensor, If the dust gets too concentrate around the laser beam, it will definitely have a hard time tracking where exactly the red dot on your target object. In extreme dust conditions, it will be hard to take the measurement because of the reflection the laser beam in such a case.

Yes, it is possible to measure a moving target. However, it depends on the speed of the moving target. The laser measurer conducts several rapid recalculations to ensure that it stays within the stated accuracy. So, in case of a moving object, the measured distance will be the mean value of the distance from where the object started and ends.

here is no difference between the devices sent out for the express and earlybird rewards. When we were preparing for our final prototypes we order a large enough batch of material to also run a test production on manufacturing. The really great news is that our final prototype proved to be complete. So we've decided to make a rewards card for the devices that is ready to be manufactured with the materials prepared. Also the material used in the express production is identical to the ones for the earlybirds. The only difference is in its delivery date!
