Thanks Feargus, because its all new to me I decided I'd keep a log of what the wind direction, drift, fish seen, fish taken, tide times etc. so that I might be able to see any patterns for having a good days spearfishing or when I should just decide to go somewhere else and not waste the time.
I'm sure the experienced spearos probably have this well sussed but I thought it might be useful for me to look back and know what conditions made for a good day at a particular location and if any others find this info useful to have.
Its very sensible and many fishermen in general do this also.
I keep a very basic one in a small notebook and I would be interested to see your excel sheet?
