Compass

compass

A compass is the most basic and inexpensive piece of navigational equipment and should be bought at the same time as the rest of your gauges.

In a beach or inlet dive your compass is your single most important tool - it tells you which direction is the shore. When wreck diving, a compass is useless if you don't look at it until you're lost. Take a bearing as soon as you hit the bottom, just in case. In a boat dive, directions such as "turn right from the anchor" can often steer you in the opposite direction, if the current reverses and pulls the boat around to the other side. Compass bearings are much more reliable.

Unfortunately, using a compass is not quite a no-brainer, and should be practiced until you are proficient.

Founding Fish

Oceanic adult herrings spend their days deep and come up to the shallows at night to feed, so you are not very likely to see them. Small ones may be more commonly found in inshore waters. Sometimes the marinas and inlets are full of tiny immature herrings known as "Peanuts." Saltwater herrings ascend rivers to spawn. All herrings are primarily filter-feeders, although larger ones may also be predatory on small fishes, squids, and other prey.
