Free tool · No email required

Barrel + spear + band matcher.

A step up from the speargun selector. This tool matches the full setup — barrel length, barrel material, spear diameter, and band count — to your target species, water conditions, and how you dive. Every recommendation cites the Rob Allen video it is based on.

1. Primary target species

Pick the biggest fish you realistically hunt. A 90cm reef gun will not land a 25kg wahoo, but a 130cm bluewater gun is overkill for a 3kg snapper.

2. Typical visibility

Viz sets how far you will reasonably shoot. Bad viz = shorter guns, closer shots. Good viz = longer guns, longer shots.

3. Dive mode

Sister brand · Apnea Total

Technique beats equipment spec at a certain point.

Once the gear is right, the limiting factor is the diver's technique, breath hold, and calm underwater. Freediving Koh Samui trains that part.
