One thing I have had a problem with from the beginning, weights. I use soft weights and found them almost impossible to mark. Because I loan them the students I can't also tell who got my weights. I can't tell you have many I have lost because of this. Also the diving condition I'm in are not always the best, if the product was to glowed it would be easier to see if dropped in the quarry. I have used zip ties, paint. The ties break on the paint fades off. I know I am not the only instructor who has had this problem. Good Luck with your project. |
