Compact Divers dSMB (or SMB) Digi Reel by Beaver 

Why not add a buddy line with clip as well ? 

Lightweight and therefore perfect for the traveling diver these

reels come with a  Snap Clip  

Small reel is a compact 50' it will fit easily into an dSMB case 

the Ezee release is very compact & lets the dSMB line run very freely

(the Psychedelic style was a one off for man who didn't like his kit getting muddled)

Medium size 100' will fit comfortably into a BCD pocket

Large size 150' will dangle nicely(?)

 lines come in orange or yellow or white or red(ish) or green

polypropylene replacement line is white 3mm or red(ish) 2mm 

Largest reel is probably best clipped to a D ring?

Superb on wrecks or for deploying an dSMB during ascent

Weight with Clip < 150 grams

Reel diameters 75mm by 1 cm (naturally larger reels are wider )

(in old money 5 oz & 3") except the 

ultimate reel is circa 2" & weighs 30 gram & with 20' line 

it's smaller than a bag of crisps but man enough for your decompression stop

yellow line (circa 100') & double ended bronze clip is shop soiled
