Check the hose lenght and form to your needs

thanks John (UK) for making the pics for us

We hope these pics clear some discussions on the hose extensions 45 or 90

Standard, no extension, using a wing and backplate

hoses definetly too short for comfortable diving/breathing/moving head,
special when you add a drysuit and the unit is farer away!

Same system with 45 degree angles.

longer hoses, going a bit straight up.

Good for tall persons or if Dolphin is really down when using a backplate

90 degree angles, hose is going smoothly over the shoulder

Good solution for normal Dolphin and if unit is high.

Maybe a minor solution for tall divers using a backplate system

Best is to turn the angles a bit to outer direction, as you may see on the picture
