There are other propelling underwater devices, as underwater sea-scoorters, but any of them gives the sensations given by DOLFINE.
The main advantages of DOLFINE vs. sea-scooters are:
- DOLFINE is very noiseless: it doesn’t scare away the marine fauna.
- Much higher performance of monofin vs. propeller (80-90% vs. 40-50%): this means higher autonomy, smaller/chiper batteries and lower charge time.
- More aerodynamic due to the fact that is located behind the swimmer, which means no increase of front surface.
- Free hands: possibility of carrying by hand other objects as camera, flashlight, etc.
- No risk of penetration of objects in the engine.
- Lower maintenance.
- Cheaper than a high range sea-scooter (the comparison vs. an entry range sea-scooter doesn’t apply).
DOLFINE runs with electrical batteries, and the electronic control buttons are in a box which is fixed to the swimmer's chest with a harness.
