All 51 ERDI laser rangefinder modules

Range-first, with blind zone and the published single-unit price · figures from the manufacturer's catalogue, verified 2026-10-23

Every class below is a board-level module with UART-TTL output. Pick the range band you need, then check the blind zone and the supply rail before comparing price — a module that cannot read below 4 m will not do terrain following at 0.3 m, whatever its maximum range says.
