Geo Scientific Ltd manufactures current meter - Swoffer 2100, consisting of a handheld digital display connected to a fibre-optic sensor and is available in three rod-configurations - a top set wading, combination and telescoping rod. Top set wading rods are designed to be used while wading in streams, waterways and channels. Combination rods are designed to measure flows in faster, deeper water or from low bridges or a boat. Telescoping wands, which are supplied with sensor, are designed for reaching shallow and partially obstructed channels such as sewers. Average water velocity in both m/s and ft/s can be viewed on the standard Swoffer 2100 handheld display, which is also used to calibrate the fibre-optic sensor.
