结论:
结论:会游泳可以选全干式 / 半干式 ,不会游泳选全干式的,不惧水的大神可选湿式呼吸管。
湿式呼吸管:
其实就是一根管子加一个咬嘴,进水时则必须泳者吐气将水喷出,此类简易式呼吸管对于有游泳技巧及学习过浮潜者来说难度不大,但对于初学者来说,极可能无法一口气将管中积水喷干净而呛水。
半干式呼吸管:
则是在咬嘴前端有一个活门,阻止水进入嘴中,但管中仍有水,呼吸有些许阻力。在潜水超过呼吸管深度时,水会进入管内,管下部可排出后可避免水直接流入口中,是初学者较为容易入门的装备。
全干式呼吸管:
则是在管前设只出不进的活门,保持管子不进水。属于进阶的呼吸管,在呼吸管上方进气口,加装了一个单向进气阀,我们叫它全干呼吸管,因为有这个单向阀,即使管子整根在水里,也不会进水。不过,多了个部件,吸气的阻力当然也稍微大了点。其顶部有活动的浮阀,一旦有水即将淹没呼吸管,浮阀就会因为浮力而封闭管口,阻止进水。
