Guys, below is George's take on ice diving. The method used to ice dive by the 'Swedish Brothers' was explained in my first post on this subject. I guess they use the reels for the wrecks, and as Dale reccommends, it is probably better to use the polypropelene line when you don't have tie in points. ss -----Original Message----- From: trey@ne*.co* [mailto:trey@ne*.co*] Sent: October 24, 2000 12:53 PM To: Schultz, Steven Subject: RE: Ice diving sure -----Original Message----- From: Schultz, Steven [mailto:Steven.Schultz@sp*.gc*.ca*] Sent: Tuesday, October 24, 2000 12:46 PM To: 'trey@ne*.co*' Subject: RE: Ice diving can I post this to the list? ss -----Original Message----- From: trey@ne*.co* [mailto:trey@ne*.co*] Sent: October 23, 2000 4:21 PM To: Schultz, Steven Subject: RE: Ice diving "DIR" ice diving is not doing it, but if it were me doing it, I'd take the tether, the floating line, the cave line, the swept ice, the whole bit.Obvoiusly the gear is not compromised just because there is ice, but you already covered that. Actually, the guys to ask about this are the Swedish Brothers - they dive through the ice in the Baltic Sea on wrecks. In a cave or wreck, if you break the line, there are ways to find it and get out of it. Under ice, those things don't hold up. -----Original Message----- From: Schultz, Steven [mailto:Steven.Schultz@sp*.gc*.ca*] Sent: Monday, October 23, 2000 4:06 PM To: 'trey@ne*.co*' Subject: FW: Ice diving George, can you shed some light under the ice?? ss -----Original Message----- From: CaptnDale@ao*.co* [mailto:CaptnDale@ao*.co*] Sent: October 23, 2000 3:59 PM To: Steven.Schultz@sp*.gc*.ca*; techdiver@aquanaut.com Subject: Re: Ice diving In a message dated 10/23/00 1:45:31 PM Central Daylight Time, Steven.Schultz@sp*.gc*.ca* writes: << The original question was how to ice dive DIR. Although what you describe is safe, and often used, I'm doubtful that it's DIR.

From his own posts, DIR is what George says it is and nothing more or less. You could ask George what DIR for ice diving is and maybe get an answer. I am sure that he has been reading these posts. However, I do not think that George is an ice diver. I do not want to put words in George's mouth, but, I believe that DIR is a philosophy that puts proper attitude, simplicity and safety first. I see no reason to change anything about your basic DIR equipment configuration. I do, however, think that having a large diameter floating line attached to the diver, anchored topside and tended by a trained tender is a safer alternative to using a thin, sinking line anchored only topside and handled by a diver with thickly gloved, cold hands. I doubt that is a violation of the basic DIR philosophy. Tie points for a penetration line underwater on most ice dives are practically non-existant. If a diver were to drop his reel it might be extreemly difficult for him to find it again. Using a tender increases safety by relieving the diver of most of the line handling. The tender also makes sure that the end of the line remains attached topside. Using large diameter floating line reduces the danger of entanglement and keeps the line out of the silt. I would only use a penetration line if I had suitable intermediate tie points, such as when doing a wreck dive beneath the ice.
