tack. The Spyder cannot withstand the impact of heavy objects like scuba cylin-

Store your Spyder in a dry place when you are not using it.
The Spyder will display a battery symbol as a warning when the power gets too

The water contact can be cleaned with a soft pencil eraser.
IMPORTANT: The Spyder should be soaked, then thoroughly rinsed with fresh
water and then dried with a soft towel after each dive. Make sure that all salt
crystals and sand particles have been flushed out. Check the mineral crystal for
