Ideal for use as a counterweight or to steady a light stand, the OR-83H Horizontal Sand/Water Bag from ORCA has a clever saddlebag design that weighs just 1 lb when empty, a real benefit to location shooters who don't want to ship or lug a heavy bag. Made of durable tarpaulin material, the bag can be filled with either sand or the separately available water bladders, also from ORCA.
The OR-81B Water Bladder is sold separately and can hold up to 4 litters (about 1 gallon)! Two bladders are needed to fit one OR-83V or OR-83H (one bladder in each side).
