    Questions about this item:

    Shopper  Why Did You Choose This?
    DON S  Price seemed right!
    Shopper  what is the range on this for night diving?
    AMMAR A  I've tried it twice during night diving. Visibility was terrible but was able to see the flashing led from approx. 6 meters away. With good viz no doubt it can be seen from a farther range.
    Shopper  Is this bright enough to use as a strobe for North Atlantic wreck divinig? (i.e., to tie off on the anchor line.) If not, which models that you have are appropriate?
    LeisurePro S  For emergency stobe you will need something stronger like Tektite Xenon Strobe 200 .For a marker light your choice would be fine
