Scuba Diving Accessory: Aluminium Underwater Noise Maker
This is an aluminum underwater noise maker, another alternative to tank bangers
. Get someones attention by just shaking this "rattle".
Contains two ball bearings that make a distinctive noise when shaken.
Comes in anodized finish with a barrel lock lanyard. Measures approx 1/2 x 7 inches (2cm in diameter, 18cm long) - fits easily in a pocket.
Most impressed with the recent purchase, excellent compact design which produces a fantastic log book stamp. The ordering process was simple and the speed of delivery was most impressive. A professional company and product that I will be eager to recommend to friends and family.
