lpg gas detectors

Can you please advise on inexpensive lpg gas detectors, for use in a narrowboat?

WW says:

Gas detectors are often not very successful on boats as the sensors are susceptible to damp. This coupled with the best location being down near the floor as LPG is heavier than air and will collect in the bilge, means that they need to be checked regularly and should not be relied upon.
A simple means of checking the gas system is to fit a bubble tester in the gas locker. This is a device with a button on top, which when pressed switches the gas flow through a clear chamber containing oil. Any flow of gas can thus be seen as bubbles in the oil. Testing with a pilot light or small burner on low flame will produce a flow of bubbles, but with all appliances off there should be no bubbles at all. No bubbles for about 30 seconds, means that the gas system has no leaks. Thus the gas system can be checked regularly, rather than only every four years by the BSS examiner. Residential boats should have one as it means that any BSS examiner can examine the boat rather than having to find a Gas Safe registered examiner.
