Frequently Asked Questions

If I have a CARGO-SAFE™ receiver, can I use that instead of a CABIN-SAFE™ receiver?

Yes, a  CARGO-SAFE™ receiver is very much more sophisticated than a CABIN-SAFE™ receiver and will perform very well with a CABIN-SAFE™ transmitter.

No. Although a signal would be able to be heard, there is no display on a CABIN-SAFE™ so the extent of the hole would be unable to be evaluated.

No. The output from a CABIN-SAFE™ transmitter is very much smaller than a CARGO-SAFE™ so no signal would penetrate any leaks and the OHV would be too small to base a reading on.

The principle of our SONIC LEAK DETECTOR™ (SLD™) is to pick up any sound with a frequency higher than what we can hear, from 15 kHz up to 200 kHz. this wide range is made possible by using a sophisticated microphone. Most manufacturers only listen to frequencies around 40KHz.

Detection depends on the amount of leak, if it is a tiny slow leak, it might produce bubbles in water. This will be very hard to detect because the slow speed of escape of the gas will not produce vortices, so no noise will be generated.

If the escaping gas is more rapid, then it can be detected – and you can work out what equipment you need depending on the volume of the noise is.

If it is loud, then a pair of padded headphones are needed as opposed to the simple skeleton headphones provided with the set as standard.

Because our SONIC LEAK DETECTOR™ has such a wide frequency range, it makes it a very good bat detector, picking up any species of bat, as it doesn’t need to be tuned to any particular frequency.

Although the SONIC LEAK DETECTOR™ comes with hard hat type headphones. Any set of headphones or earphones will do, as long as they have a 3.5mm jack, mono or stereo. For noisy environments, you can use DJ type headphones, or the style that have large soft ear pads that fit completely over the ears and exclude any extraneous noise.

A brief answer as it depends on the amount of leak, if it is a tiny slow leak, it might produce bubbles in water. This will be very hard to detect because the slow speed of escape of the gas will not produce vortices, so no noise will be generated.

the leather cases are not just stormproof, and there to keep the instruments clean, they are also designed to withstand being dropped 2 metres or 6 feet without damaging the equipment.

the leather cases are made from English Cowhides and use a process called ‘splitting’. This divides the hide in two which halves the thickness of the leather, the two halves are then coated with a vinyl plastic to make the resultant leather supple, smooth and weatherproof. They also offer protection from dust, grease and debris.

The magnets are made from Neodymium, which is the strongest magnetic material known. They are coated in nickel to protect them from corroding.

Just about any liquid can be used, as all liquids conduct ultrasound. Gels are generally used because they stay where they are placed.

There are different types of couplant, however, water-based couplants can be a problem when applied to steel, as unless it is cleaned off it can cause the steel to rust.

Oil-based couplants are OK for steel, but may stain plastics.

Silicon based couplants can be used for high temperature use, over 60°C / 140°F.

In an emergency, any liquid can be used – some people even use spit.
