I have a cheaper solution: "If you ever pull that s*** again, I'm not diving with you anymore".
And my solution doesn't need any batteries.
flots.
I worded that poorly, in that I meant it could be a great tool or good tool, but never intended to say it was the greatest tool. I need to proofread better. My apologies.
I've been diving solo (proper equipment, training, experience) for some time now and actually have quite a few more dives solo than with "buddies". I really don't like diving with others. I'm selfish and don't want to babysit, keep track of, be limited by, etc. etc. etc. I only dive with buddies when I have to - the exception is the Milfoil remediation team on Brant Lake - we work well together, but then we are doing a job not diving for pleasure. Experiences like this one simply reinforce my desire to dive solo.
Now a different picture is beginning to emerge on how that separation may have occurred, at least some of the underlying factors that were not evident in post #1.
