Things to watch out for:
Avoid bug hunting in dense kelp areas when visibility is poor. You can find you and your dive buddy in a tangled situation. Make a good dive plan, take into consideration everything around the area where you are bug hunting, rock formations, dense kelp, etc... Try to go slow and easy ,you will find more bugs this way. You will be more likely to scare some off and also miss some if you swim around to quickly. Make sure you and your dive buddy are in agreement on this, before you dive. Going to fast is probably the worst thing you can do. It can potentially land you in the middle of kelp that is to dense. You should be able to safely navigate through the kelp. If it looks unsafe for you to go through it probably is! Find the safer route through the kelp, always stay close to each other. Make sure you have a knife or shears to cut fishing line or kelp if one of you should become tangled.
