We teach teams to put a figure 8 in the com line and attach it to our locking carabiner on our harness just like we would any tether line. We have been doing this for over 30 years and it works well. The com lines we have are used for hundreds of dives annually and we have no problems with them.
Make sure to tuck the com wire (between the com line and the full face mask) into your harness so it’s not dangling. Attached is a photo. I’m not sure if it will send out. If it doesn’t, and you want to see the photo email me at firstname.lastname@example.org with your email address and I’ll send it to you.
We strongly recommend hardwire. They very rarely fail, and they serve as your tether line. Bob Kinder wrote plenty of good points about hardwire that don’t need repeating.
safe diving always,
