FAQ
Which is the lowest-priced drone altimeter laser rangefinder module?
Among the models listed, the LRF22VB has the lowest published price, From $8 per unit with shipping included.
Which is the lightest drone altimeter laser rangefinder module?
The LRF22VB at 1.5 g is the lightest of the models listed.
Why does every range figure show a condition?
Vendors measure range on different targets (white board, building, 10 percent reflectivity) and in different visibility. A number without its condition cannot be compared, so this page lists the condition next to each range.
