After presenting the Ultimate and Supreme 2019 fins by Pathos, here the third and last offer, the Pathos Maximum, more intended for Pathos Maximum data chart shallow and mid water spearfishing, something very useful this time of the year in the cold Northern emisphere.

Best for which kind of use?

In the line-up of carbon fiber fins by Pathos the Maximum are thought for very fast spearfishing in shallow and medium water.

This part is key and another step forward for Pathos blades compared to the previous versions and to competition. The blades of the Maximum are, just like the Ultimate, made of 100% carbon composite, but utilizing two different fibers, the 285 T4 4×4 twill for the external surfaces, a solution intended to be more flexible and resistant to cracks, and the 285 T2 2×2 twill internally, for best reactivity. In particular, Pathos goes into very professional and deep detail of the materials used. The T4 has an areal weight of 285 g/m2, with tensile strength of 3530 MPa, tensile modulus of 230 GPa, and elongation at break (%) of 1.5. This parameter of course does not consider breaking at fatigue, meaning inferior elongations repeated many many times, which can lead also to cracks. The T2 the same parameters, but 2×2 twill, which determines different final characteristics.

Design and external look

Glossy surface and extremely high perceived quality for the Pathos Maximum blades, with the quite traditional look of the twill carbon fiber. Somehow the appearance of the new blades also indicate a step forward compared to the previous generation of fins, the Pathos Abyss, that had actually obtained the best results in the Y-40, the deepest pool in the world, in the descent and ascent phases of the dive.

Tip of the blade has a convex flap shape for best push during the final phase of the kicking, while water rails, of constant 16 mm total height, are positioned along the blades for total 27 cm, and are small to avoid interfearance with the bending of the carbon fiber, no excessive weight increase and no overlaod on the blades, which would effect the fatigue on the legs. Remember, in fact, that water rails avoid water sliding excessively laterally to the blade instead of along it, but an axcessive height of the water rails can determine too much water remaining on the blade and loading the legs of the spearo too much. An example of this situation can surely be the C4 Mustang HT with the EVO variable height patented water rails, intended to generate maximum push at every kick, but determining surely a very heavy feel on the legs.

On the Maximum the longerons are longer (the cut is further up along the blade) compared, for example, to the Ultimate.

Angle between foot-pocket and blade is 24°, a medium value angle that gives good performance, and is easy to use, with no need of extreme training by the spearo. This is, compared to the Ultimate, one of the key differences, together with a very different bending curve and smaller dimensions of the Maximum blades.

In fact, dimensions of the Pathos Maximum blades measured by AP are length equal centrally to 62 cm from the curve under the footpocket to the tip of the flap, and 54 cm laterally to the flap. The maximum width of the blade measured inside the water rails is 18.8 cm. Thickness of the blade goes from 0.66 mm on the tip of the flap, to 0.88 mm at mid length, and 1.25 mm almost in front of the footpocket, indicating a more rigid part in front of the foot-pocket compared to Supreme and Ultimate.


Differently from the Pathos Ultimate and the Pathos Supreme fins, the bending curve of the Pathos Maximum is shifted to the tip of the blade more similarly to the previous Pathos Abyss fins, starting about 10 – 15 cm from the tip of the foot-pocket.

Pathos Maximum bending curve

To obtain good performance during kicking and an easy to use fin, the positioning and the cut of the layers of the carbon fiber have been implemented to obtain a C type curve, meaning a curve that starts almost at mid length of the blade.
