Do you consider which lifejacket inflator is in your lifejacket when you make the purchase?
Most lifejacket brands market themselves as the best at what they do and why wouldn’t they? So how do you the user wade through all the information and decide which type of lifejacket to purchase? Lifejackets are a bit like cars. Manufacturers have several different makes and then within those makes they have subcategories with slightly different buoyancy levels, features and inflation mechanisms.
There are 3 commonly found makes of lifejacket inflator and they are used by most manufacturers. These are
- Halkey Roberts – a US Manufacturer.
- United Moulders – a UK Manufacturer.
- Hammar – a Swedish Manufacturer.
All have manual options as well as automatic options.
Manual Options are straight forward as you pull the toggle and the lifejacket inflates. It has the additional backup of an oral inflation tube.
Automatic Options are also straightforward. You fall in the water and the lifejacket inflates. It has the additional backup of manual toggle and oral inflation tube.
The HR and UML Auto inflators work in a similar way. They have a capsule that dissolves on contact with water and then releases a pin to pierce the CO2 cylinder and inflate the bladder.
The Hammar is a hydrostatic device that requires water pressure to initiate inflation.
All three makes have minor pros and cons which I may deal with in a later post, but my preference is for the HR and UML method and they are the most widely used in the UK.
A few brands of lifejacket have developed their own inflators which are only available in their make of jackets. Some have versions of existing inflators that have been slightly redesigned eg. with a slightly different clip or screw thread.
So how do you pick which one and should you even consider the lifejacket inflator type?
The first consideration is whether you need manual or auto inflate. Manual inflate might be for someone who is often immersed in water and for whom an auto inflate would mean constant inflation and re-arming. You need to consider as well though that in cold water it isn’t always easy to initiate manual inflation.
Once you have decided whether auto or manual, ongoing costs are one factor you should consider as in the main all three common makes are pretty good inflators. A simple Google Search will identify that you can buy unbranded re-arming kits for HR and UML inflators in many places at competitive prices. Branded re-arming kits are usually more expensive, sometimes double the price. Many branded spares are often just standard HR or UML Spares nicely packaged in a blister pack or on a header card.
My preference is for a device fitted with a Halkey Roberts or a United Moulders device unless I have a good reason not to. If I keep the lifejacket for several years it may well save me more than the original price of the lifejacket in ongoing maintenance and replacement parts.
Both makes are simple and relatively inexpensive to re-arm and very reliable systems.
