View Full Version : IST Signaling Stick (the tank marker on steroids)

My fantastic husband norine62 got me the signaling stick and battery recharger for my birthday. As I was checking it out I noticed a small hole down near the very bottom, close to the loop where the wrist lanyard would loop through. This small hole is threaded, as if something should screw into it. Any one out there that has this signaling stick and knows what this random little mystery hole is for? I checked the IST website but they don't mention it at all.

Not sure about the threaded hole but I do know that IST has really good products. I thought about buying this one myself. On the IST website they have an e-mail diving@istsports.com (diving@istsports.com) and maybe they could help.

Curious as well, and let us know how you like it, we've been debating if we should grab them for our upcoming trips.
