The Kaymont TX-600g balloon is an excellent intermediate sized balloon, and we commonly recommended this balloon for education and training. Before launching balloons larger than this, we suggest users familiarize themselves with the safe handling, inflation, payload attachment and tie-off procedures that are critical to successful weather balloon launches. When properly launched, our TX-600g balloon with a 2lb payload will reach an estimated 88,000- 92,000 ft (26822- 28041 m) burst altitude. For heavier payloads, use our Prediction Tools & Burst Calculator.

These balloons are recommended for individuals or groups who have experience in high altitude balloon launches. Balloons are ideally inflated with a target ascent rate of approximately 5 meters per second. When properly launched, our TX-800g balloon with a 2-4lb payload will reach an estimated 95,000- 100,000 ft (28956- 30480 m) burst altitude. For heavier payloads, use our Prediction Tools & Burst Calculator.

The 1000 gram balloon is the workhorse for gathering upper air data before US Space Force test ranges on both the East and West coast. Balloons are ideally inflated with a target ascent rate of approximately 5 meters per second. When properly launched, our TX-1000g balloon with a 2-4lb payload will reach an estimated 1000,000- 105,000 ft (30480- 32200 m) burst altitude. For heavier payloads, use our Prediction Tools & Burst Calculator.

The 1200 gram balloon sets the standard for ozone research across the globe. Balloons are ideally inflated with a target ascent rate of approximately 5 meters per second. When properly launched, our TX-1200g balloon with a 2-4lb payload will reach an estimated 105,000- 110,000 ft (32004- 33528 m) burst altitude. For heavier payloads, use our Prediction Tools & Burst Calculator.

The 1500 gram balloon is an extremely popular choice for high altitude photography. With a 4 to 8 pound payload, users can expect to consistently reach over 100,000 ft. When launching this type balloon, and payloads of this weight, it is assumed that the operators have prior launch experience and are familiar with FAA requirements. Balloons are ideally inflated with a target ascent rate of 5 meters per second. When properly launched, our TX-1500g balloon with a 4-8lb payload will reach an estimated 110,000- 115,000 ft (33528- 35052 m) burst altitude. For heavier payloads, use our Prediction Tools & Burst Calculator.

Introduced in 2021, the 1600 gram balloon fills a unique request from high altitude ballooning enthusiasts. The 1600g balloon offers a slight competitive edge over the 1500g balloon, when every foot of altitude counts. When launching this type balloon, and payloads of this weight, it is assumed that the operators have prior launch experience and are familiar with FAA requirements. Balloons are ideally inflated with a target ascent rate of 5 meters per second. When properly launched, our TX-1600g balloon with a 4-8lb payload will reach an estimated 110,000- 115,000 ft (33528- 35052 m) burst altitude. For heavier payloads, use our Prediction Tools & Burst Calculator.

The 2000 gram balloon is designed for heavier payloads, with a reinforced 5cm neck and expanded lifting capacity. These balloons are made to lift heavier payloads to altitudes reaching over 110,000 feet. Balloons are ideally inflated with a target ascent rate of 5 meters per second. When properly launched, our TX-2000g balloon with a 4-8lb payload will reach an estimated 112,000- 118,000 ft (34137- 35966 m) burst altitude. For heavier payloads, use our Prediction Tools & Burst Calculator.

The 3000 gram balloon is the ultimate workhorse for heavy payloads, and is responsible for setting multiple world records for exceptional feats of high altitude ballooning. In 2016, Third Man Records, the Nashville label founded by Jack White, launched a gold-plated vinyl copy of Carl Sagan's "A Glorious Dawn" actively playing on a turntable lifted by a Kaymont 3000 gram balloon to 94,000 ft. The payload was 25lbs. When properly launched, our TX-3000g balloon with a 4-8lb payload will reach an estimated 120,000- 125,000 ft (36576- 38100 m) burst altitude. For heavier payloads, use our Prediction Tools & Burst Calculator.

The 4000 gram balloon is the MOAB, Mother of All (Weather) Balloons. Despite a long track record of successful high-altitude launches, we still consider the 4000g an experimental balloon, due to its incredible size and lifting capacity. The 4000g balloon is typically excluded from burst calculators and we only recommend this balloon for users with extensive high altitude balloon experience. When properly launched, our TX-4000g balloon with an 4-8lb payload will reach an estimated 125,000- 130,000 ft (38100- 39624 m) burst altitude. For heavier payloads, use our Prediction Tools & Burst Calculator.
