The V4e Pro is a 320g handheld RTK receiver aimed at the everyday reality of fieldwork: not every point you need to survey or stake out is somewhere you can safely stand. Its built-in laser rangefinder measures offset points at angles up to 60° with roughly 2.5-3.5cm 3D accuracy, so an operator can hit a corner, kerb line or hazardous point from a safe distance rather than walking to it. Multi-constellation RTK gives sub-centimetre-class horizontal accuracy, the case is drop-tested to 1.2m, and a single charge covers a full working day (12+ hours). It also pairs with a V4e LiDAR scanner as the "V4e Combo" to georeference indoor-to-outdoor scans. A practical, low-cost RTK option for topographic survey, road survey, utilities and general construction layout.
