COOPER-RAND comes with 2 sets of two 9V. batteries, two 40" connecting cords and a package of 10 tubes (8 soft and 2 capped, semi-rigid so user can try both types). The "old and still gold" standard intra-oral instrument. Proven durability - many C-Rs over 20 years old are still in service. Unique two-piece design, so that only the 1 oz. Tone Generator (TG) is hand-held. Uses two 9V. alkaline batteries which last 4 - 6 weeks instead of changing or recharging daily - a great asset for those with dexterity or memory limitations who need help changing batteries. Easily accessible dial controls for both pitch and volume on the top of the Pulse Generator (PG). Pocket safety clip on PG. The only AL with practical adaptations for hands-free use or for those with little or no use of hands or arms.
