Interview with Duncan Henderson
Big chat with final year, mechanical engineering student Duncan Henderson who has spent way too long geeking out on spearguns – you’ll see what I mean. We chat shaft length, diameter preferences, rubber diameter (the force triangle) along with common speargun issues. Duncan also relives three terrible poo stories and a memorable Yellowtail Kingfish. Enjoy!
