JZLiner DSMB 6ft Surface Marker Buoy with 100ft Finger Spool Reel Diver Below Signal Flag Tube Scuba Diving Equipment Open Bottom Set

It serves it's purpose, and feels quality. Just be careful when inflating. Make sure it's free to zoom up to the surface if released from depth. You don't want to rocket to the surface with it if you're under deco obligations. Practice makes perfect, so practice sending it up, to perfect your technique. Perfect for inflating after you surface as well. This thing is long, so it should be easily seen. Go ahead and grab one, and safe diving.

Great DMSB. Have 3 of them (2 small ones for my kids and a large one for me). Used them about 10 times. Reel is metal, line (about 100 feet) is strong, flat and orange (high viz) to avoid enranglements.Buoy can be inflated from bottom (my preferref method), by mouth (ir BCD hose, though I have no idea why you would do that).No issues with the product at all. Just used a bigger snap-clip, but there was nothing wrong qith the original (just preference)

It is very difficult to get enough air from a reg into the DSMB to properly inflate and send up. I use the inflator hose which is akward with a finger reel. I like the reel but this doesn't work for me unfortunately.

It's definitely bigger than expected, which in my case is a great thing. The spool and cord are of great quality, I can't recommend this set up anymore. Money well spent.

This is a phenomenal surface marker buoy combo. You really can't beat the price nor the features. If it feels like high quality construction the aluminum spool feels great it's nice to have the stainless steel clip lock although I upgraded mine to a 4-in just out of personal preference.

Bought one for myself a couple of years ago. It has been used in a couple of countries and at the local pool and lake for demonstration purposes. I purchased this one for my son who is a new diver as this is the most important piece of kit we carry aside from air.... LOL Purchase with confidence.

As described

Would not inflate from the supposed open bottom with the second stage regulator. I tried, the divemaster tried, we all tried. Finally inflated it using in my BCD low pressure hose. I bought for open bottom but I wish I had not bought it.
