Rob Allen Tangaroa Carbon 120cm Speargun
Rob Allen Tangaroa Carbon 120cm Speargun
The Dive360 Take
The Tangaroa puts a distinctive blue-and-silver finish on a 120cm carbon-barrel gun. Its single 20mm rubber and 7mm shaft make it a different setup from the twin-band models in this batch.
We would consider it for divers who already know they want a longer carbon gun and are comfortable with that band configuration. Match the 120cm length to your visibility and hunting terrain, and make loading comfort part of the decision.

| Speargun length | Best suited to | Typical NZ use |
|---|---|---|
| Under 75 cm | Tight spaces & close-range hunting | Cray holes, caves, shallow reef and dirty water. Compact and easy to manoeuvre when visibility is limited. |
| 75 cm – 1 m | Reef & weed-line hunting | Great for butterfish, blue moki and close-range snapper. A versatile choice for typical coastal diving and moderate visibility. |
| 1 m – 120 cm | General NZ spearfishing | An excellent all-round range for snapper, kingfish, trevally and reef species. Good balance of range, accuracy and manoeuvrability. |
| 120 cm+ | Clear water & larger fish | Best when you need extra range and power—for kingfish, deeper pins and open-water hunting where visibility allows longer shots. |
NZ tip: Bigger isn't automatically better. Match your gun to the visibility and terrain you dive most often. A shorter gun can be much easier to use around reefs and weed lines, while longer guns come into their own in clear, open water.
