💕TIPS:

▪️8 CIRI PILIH SMB

1. Metal D- Link Connector

• plastik senang pecah
• elakkan juga plastik clip

1. Closed- Ended

• elakkan beli yg Open-Ended
  3 Inflator
  -beli yg ada inflator.. nak tiup pakai mulut senang

1. OPV ( Over pressure valve)

• boleh juga guna sebagai deflator

1. Kecik vs Besar

• Beli yang 1m panjang
• SMB panjang dan besar perlu banyak udara utk inflate.. risk utk failed deployment dan increase risk utk entangle.
  -kecik: masuk udara sikit saja

1. Light reflector

• if boleh beli yg ada reflector.. senang bila gelap orang suluh boleh nampak

1. Reel/Spool
   15m vs 3Om.. if boleh beli yg 30m
2. Double ender

• kecik vs besar.. if boleh beli yg besar sikit size 90mm.. senang nak pegang dan ikat

🔸ADD ON dari Andy Davis

Personally, I advise:

• Avoid buying models with useless lead strips
• Avoid models with long webbing to the D-ring (entanglement hazard)
• Remove useless velcro (slow and silly), if present. Seriously, why?
• Use bungee retention only to stow
• Semi-sealed aren’t necessary, oral-inflate is the best practice method.
• A single breath is used to initiate DSMB ascent to avoid hazardously excess buoyancy.
• For larger volume DSMB, simply deploy from a calculated depth to allow gas expansion to fill the bag (that’ll happen with a 3′ bag from 3m depth, 6′ bags demand a deeper deployment depth).
