The same balloon that ships in our Balloon Mapping Kit, this 5.5 foot (170cm) latex/chloroprene (neoprene rubber) balloon is ideal for carrying cameras up to 4,000 feet. These UV-resistant balloons can stay inflated for hours, and last for a dozen* flights if well cared-for. Buy a single balloon here without a kit to replace one that's popped, or buy one as a backup if you're planning on doing a lot of mapping.
*We are seeing 5-12 inflations if the balloon is minimally filled (40-50 cu ft) 3-5 if it is medium inflated (60-70 cu ft) and 2-3 inflations if the balloon is filled all the way to 70-87 cu ft. The temperature changes, sunlight, human skin oils, dust, and abrasions the balloon is exposed to significantly effect longevity. Color is red, not blue as pictured.
