FMS SCUBA Diving Tank Banger Signal
Communicating underwater and getting your dive buddy's attention can be difficult if you don't have an effective means of getting their attention. The simplest, most proven and reliable way to get someone's attention is with the Tank Banger. The construction is comprised of a heavy duty, non-corrosive plastic ball that is paired with premium quality shock cord that features a 100% stretch and a unique diamond shaped ultra-grip cover. The Tank Banger easily slips over any SCUBA cylinder and is meant to hold up under the harshest conditions.
