[Acoustics] Laser rangefinders - availability of a rangefinder cheaper and lighter than an Impulse

[Lloyd T Brooks]

Has anyone found a rangefinder that has +/- 1 ft accuracy and is lighter, 
smaller and cheaper than an LaserTech Impulse 100?  We use rangefinders 
for ADCP and wading (<300 ft wide sections) measurements.
Thanks, Tim
