Spearfishing Floats and Lines

The Scuba Doctor has a range of quality floats, flags and float lines available for all types of spearfishing.

Spearfishing Float Lines: — It is important to attach a float line to your gun and your float for many reasons. Having a float line means that you can drop your speargun and retrieve it from the surface by pulling the float line up. Whether you have shot a big fish or got your gun stuck in coral it is important to have a float line so that you do not lose your speargun!

Float lines are made by a variety of materials and come in all different colours. It is important to have a float line that suits the diving you are doing. A dull green or black is the best colour for a float line as it will make you less obvious to your prey. Float lines made of high-quality bungee cord are great for hunting big pelagic species, but if you are just hunting smaller species a ski rope style float line is an ideal option if you are on a budget.

Spearfishing Floats: — You need an easy to tow surface marker float that stays on the surface while you're spear fishing. The dive flags on these spearfishing floats are used to alert anyone on the surface that there are divers below.

DISCLAIMER: No claim is made by The Scuba Doctor as to the accuracy of the dive site coordinates listed here. Should anyone decide to use these GPS marks to locate and dive on a site, they do so entirely at their own risk. Always verify against other sources.

The marks come from numerous sources including commercial operators, independent dive clubs, reference works, and active divers. Some are known to be accurate, while others may not be. Some GPS marks may even have come from maps using the AGD66 datum, and thus may need be converted to the WGS84 datum. To distinguish between the possible accuracy of the dive site marks, we've tried to give each mark a source, e.g. GPS, Google Earth, or unknown.

If you don't understand the differences between the different ways coordinates are given, plus how different datum come into play, you might find the article GPS Conversions by Lloyd Borrett a useful read. It describes the problems associated with locating dive sites using a GPS receiver.
