Halcyon Slim Big Alert Marker

Halcyon Super Big Slim Alert Marker
The Halcyon Slim Big Alert Marker is a combination of the Halcyon 6 foot SMB's height and the width of the smaller Halcyon SMB's. Divers often found it difficult to fully inflate the 6 foot SMB even from depths of around 30m, as an SMB is typically sent up from the first decompression stop at 21m this meant a lot of bag weren't fully inflated at the surface. It is easier to fully inflate the 4.5 foot bag but divers wanted something bigger. Enter the Halcyon Slim Big Alert Marker, at 6 feet long it stands well above most ocean swells but has a reduced volume to ensure that you get the full length at the surface. The diameter of the Halcyon Big Slim SMB is somewhere between the diameter of the 4.5 and 6 foot buoys and the 3.3 foot buoy, giving a good surface area when fully inflated. The Halcyon Slim Alert Marker is inflated using a low pressure inflator hose, the nipple on the SMB is smooth and therefore there is no way the hose can lock onto the SMB. Any expanding gas is dealt with by and OPV and the base of the buoy. SOLAS reflective strips and a glow stick holder ensure that the SMB can be seen at night or in marginal light, allowing your surface cover to know where you are at all times.

Reviews

Excellent product especially for CCR divingReview by John
This product meets my needs for a high visibility marker in open ocean. The 1.8m height improves the visibility in swells. The feature is the lower gas volume necessary to fully inflate the SMB on the surface. Inflating a large capacity SMB at depth can be tricky, and often insufficient gas is injected to ensure full inflation at the surface. The smaller volume of the "slim" SMB makes life a lot easier. It is advertised as have a lift of 12kg, which equates to a 12l volume. In my workshop, I fully inflated the SMB then measured the length, and the diameter. The calculated volume was approximately 10l. In my view, this is better than the 12l stated in the specification, and means that inflation of the SMB at any depth up to 20m is very manageable. A 40m release means only 2l of gas (2kg lift), and at 60m a miserly 1.4l (1.4kg lift). It also packs down to a small size, which provides options for storage.

The price and service from Aquanauts was first class as usual. (Posted on 10/05/2017)
