## Questions & Answers

**Q: Is the magnet in this strong enough to damage dive computers, cameras or other electronics? Thank you, Ashley**
A: Hi Ashley,Thanks for your question. No, the magnet is strong enough to damage electronics. If you have any other questions, please let us know.ThanksDivemaster Chris866-728-2293

**Q: How long is it?**
A: It is 6 1/4" long. The string is not as long as in the picture, you cannot loop it through, but it can be replaced.
