Spearfishing Equation from Piet van Rooyen’s Diving and Spearfishing in South Africa

Gletwyn Rubidge, a South African spearfishing champion, has written an article for African Expedition Magazine, in which he adapts Piet van Rooyen’s equation for spearfishing.

The equation was first introduced by van Rooyen in his 1987 book, Diving and Spearfishing in South Africa, the updated version of which will be released in October:

Ordinarily success is considered to be prosperous progress in any field. Success means different things to different people in different positions. What about success in spearfishing – it’s also different for each spearo.

In this article of explain an equation derived by Piet Van Rooyen (Diving and Spearfishing in South Africa) back in the 1980’s. I then proceed further to alter it and explain the alteration.

S is success in spearfishing. It is equal to the terms on the right hand side of the = sign. Add those up and it could be possible to predict the success of a spearfisherman with fair accuracy. Imagine if you could predict your success in spearfishing outings – it would take a lot of the hit and miss out of the hunts.
