Review: Nice, well constructed DSMB - Very decent DSMB Pros: multiple ways to inflate (mouth, inflator hose, regulator). Reflective tape on top. Heavy duty material and construction. Aluminum finger spool. Stainless swivel. Purge valve. 60ft of line. Stanless d ring attachment. Velcro and bungee keeps it securely rolled up. Cons: spool is small for 60ft of line making it difficult to get clip through holes (I cut 10ft off which helped resolve the issue). Loop to attach to smb d ring is on the small side but workable. A bit on the bulky side. Takes a number of breaths to inflate (easier to do with regulator). Overall very satisfied with this DSMB for the price point.
Review: Very good DSMB - I am happy with this DSMB. It has already been on one dive with me, and it held up well. I do wish the spool was a bit bigger - it works well for me.

### ⭐⭐⭐⭐⭐ Nice, well constructed DSMB

### ⭐⭐⭐⭐⭐ Very good DSMB

I am happy with this DSMB. It has already been on one dive with me, and it held up well. I do wish the spool was a bit bigger - it works well for me.

### ⭐⭐⭐⭐ Good value SMB and spool
*by A***. on August 5, 2021*

I haven't shot the SMB in the water yet, but it appears to be well made. It has double seams along the sides, which is nice. The ones with single seams can sometimes wear along the non-stitched side. It can be orally inflated (or with the LP hose) or via the octo purged into the open bottom. It is self-sealing, which is a nice feature and will keep it from flopping over and deflating on the surface. However, I suspect that exhaust from the primary will not provide enough pressure to inflate it that way; probably have to use the octo. I might be wrong, however, so I'll have to try in the water. The spool is pretty good. It has a nice, large hole so it's suitable for cold water diving with gloves on. I like that it's aluminum. Like pretty much every finger spool, you'll have to strip off some line in order to expose enough of the holes so you cal clip off a bolt snap. I stripped off about 15' and it's fine now. That leaves about 30' of line on the spool, which is good for shooting the SMB from a safety stop in most situations. If you need to shoot it from deeper or while in a strong current, this might not be enough line. The swivel and leader is a nice touch. Unfortunately, the leader is too small to be useful. The diameter of the loop is not large enough to easily slip over the spool when clove-hitching the SMB to it. It can be done, but not easily, which means it will be even more difficult in the water (and probably impossible with gloves on). I removed it and used some of the stripped line to tie a larger loop. Now it's perfect. Overall, if you are looking for a good price on a small SMB and spool, this fits the bill. Perfect for most calm-water situations when you are shooting an SMB from your safety stop. If you dive when the swell is high or when the current is ripping or need to release an SMB from much deeper, then you probably want a larger SMB and a larger spool.
