The ring acts as a ship marker and a origin lock indicator, so instead of your opponent saying "I attack ship 3", they say "I attack the green ship". Then when your green marked ship Target locks, you toss the green target lock indicator next to the enemy ship just as you always have with target locks.
this is a basic and simple way to identify your ships and their target locks..... There are 2 sizes for large and small ships just print in different colours and away you go.
you leave the ring on your ship's base this acts as the identifier and play the colour matching target lock on the enemy ship as usual.
you don't need to add number markers to each ship as you use the colour rings.
update 12.06.17 added a second version target lock
