Hi, now the summer is starting to draw to a close and having missed a few long range shots with my 75 I've decided to build my own ideal speargun. Its going to be a railgun in the 85-90 cm range,single band and made of mahogany, (got some knocking about the workshop). Was going to make my own trigger assy but time constraints and the fact that off the shelf units are so cheap means that that can wait untill another time.Got a quick question on the merits of different shafts. I would like to use a standard notched shaft with a dyneema wishbone but are these shafts compatible with neptonics triggers? can anyone reccomend a trigger assy to suit a notched euro shaft. many thanks.
