Rubber vs Pneumatic Spearguns
We are often queried about the differences, advantages, and disadvantages of rubber powered spearguns compared to pneumatic spearguns. So Adreno has compiled a table of pros and cons for each to assist you in makingyour purchase.
Rubber Powered Speagun
Pros
- You can vary the strength of the rubber and power of gun in so many more ways
- Easier to load a rubber gun once you know the technique – especially a gun longer than 90cm
- Accuracy and range of the rubber powered speargun is far better – especially a gun longer than 90cm
- The speargun maintains its power at all depths
Cons
-The rubbers will only last 6-12 months due to them perishing from moisture, UV rays etc.
-Will need to be replaced regularly
-Rubber powered spearguns are not as stream lined as the pneumatic speargun
Pneumatic Speargun
Pros
- Great for using in caves and coral overhangs as there are no rubbers which may be cut on sharp coral and rocks
- Popular with scuba divers, in territories where spearfishing on scuba is legal, as they are small and compact
- Simply pump to specified pressure and the gas, concealed in a chamber, allows for multiple reloads
- Great for spearing crayfish (where this is legal). Especially with compressed air guns that have adjustable power settings to prevent spears being jamme of damaged in caves
- Range in size from 30cm to 110cm, with the most popular sizes being 30-70cm
- More powerful than rubber powered speargun in shallow water (less than 5m).
Cons
- Pneumatic spearguns lose their power at depth
- Pneumatic spearguns can be difficult to load, especially sizes larger than 70cm. Spearguns larger than 90cm can be very difficult to load
- Pneumatic spearguns will need servicing about every two years depending on frequency of use and how well they have been cleaned and maintained
- Not all dive shops are able to service and repair pneumatic spearguns and some will need to be sent away to specialists for repairs
- Availability of different spear shafts is limited
