Gas Monitor
Liquified petroleum gas (LPG) is an invaluable source of energy on many sailing vessels. It should, however, be used with great care. In its gaseous form it is heavier than air and will always collect at the lowest level in a vessel. Any leak of gas, any spillage of liquid could sink to the bilge and, unable to escape, build up to explosive proportions.
The NASA Marine gas detector system warns if the level of LPG rises above 10% of the lowest explosive limit (LEL) giving adequate warning of the need to ventilate the area before a dangerous situation occurs. The system consists of a cabin mounted monitor and a remote sensor. The monitor gives visual and audible warning if gas levels at the sensor rise above 10% LEL and will warn of fault conditions such as damaged cables etc.
The splash proof sensor is supplied with a 5 metre cable and has a test button to check the system right through to the gas sense element. The sense element is user replaceable in the event of contamination. Supplied with power cable.

EX-1 exhaust temperature monitor/alarm
The EX-1 continually displays the exhaust gas temperature in wet exhaust systems giving advanced warning of potential problems.
The EX-1 measures the exhaust gas temperature directly and displays it in degrees centigrade or Fahrenheit. Once the normal working temperature has been established a maximum temperature, a few degrees higher, can be programmed into the EX-1 which will then sound an alarm if that temperature is exceeded.Even a small rise in temperature can indicate a potential problem such as a minor blockage, leak or failing pump which can be corrected before a complete failure occurs.
Customer review
I just wanted to share with you another great reason for having the EX-1 fitted. Over the last few weeks of using our boat I observed that the running temperature had gone up around 5 degrees or so. Now with using the boat in the winter one would expect the reverse, so it caused me to think more about it. Added to that, when I did use the engine at full revs on load (something I do regularly just as a check) the exhaust alarm went off (it doesn’t normally.) I then observed the seawater tell-tail was more pronounced (the tell-tail feed is off the line between the Jabsco pump and the inlet to the cooler. Hmmm: possible blockage? I removed the impellor and true enough, one of the vanes had come off. On stripping the cooling system (I was already working on the leaking silencer) I found one part of the impellor up against the tube stack, but more importantly, when I removed the hose feeding the tube stack, via a small elbow, I found a larger part of the impellor jammed inside, reducing the flow by as much as 50% and causing s sediment build up behind it, reducing it further. All cleaned out now, but the reason for telling you is that the EX-1 gave me warning before any real damage could have been caused. It is a brilliant piece of kit.

NMEA 0183 to NMEA 2000 SPEED LOG Compliant converter
The product consists of a translator box which inputs the NMEA 0183 speed log data sentences VHW + VLW. It translates the 0183 data into NMEA 2000 compliant speed and distance data for connection via a ‘micro-c’ connector directly into an existing NMEA 2000 network.

BM-1 Compact
Compact battery monitor, just 124 x 62mm x 23mm!
Based on the highly successful BM-1 marine battery monitor, the BM-1 Compact is especially designed for applications where space is at a premium.
Caravans, mobile homes, RV’s, small boats and renewable power installations can all benefit from the BM-1 Compact. It is able to monitor the performance of any 12 Volt lead acid battery system with a capacity up to 600 AmpHours. The BM-1 Compact is supplied with a precision 100 Amp shunt and prefabricated cables to enable simple DIY installation.
The unit continually monitors the voltage, the current (charge or discharge) and calculates the state of charge together with the time remaining to charge or discharge the battery.
This information can lead to a more efficient use of the battery enhancing its life and reducing the risk of failure.
Operation is very simple. One screen displays the voltage, current (charge or discharge) and a bar graph showing the remaining capacity. A flashing alarm is also included to warn if the capacity is getting too low. A second screen shows the remaining time available at the current charge/discharge rate together with the remaining capacity in both analog and digital format.
The BM-1 Compact consumes a miserly 1.5mA!
BM-1 Compact is used in various vehicles by the Ministry of Defence.

H Vector Navtex Antenna
Conventional navtex antennas respond to the electrical component associated with the navtex radio signal. They usually perform well at sea where electrical interference is low but can sometimes be overwhelmed with interference especially when in harbour and connected to shore power.
In most small craft the electrical system acts as an effective ground for the antenna but it can also be a source of interference conducted from other electrical equipment on board. Electrical interference can result in poor reception especially in a marina where the ambient level is high or at sea when poorly suppressed electrical equipment is in use.
The omnidirectional H-Vector antenna is not sensitive to electric fields but to the magnetic component of the navtex signal. As a result it is less sensitive to locally generated interference and, as it does not need a ground, it is not affected by conducted ground interference whether in harbour or at sea.
The net result is that, under adverse conditions, the H-Vector antenna can deliver a significant improvement to navtex reception. The mushroom shaped antenna is compatible with the Clipper navtex, series 2 Target navtex and with the navtex engine. It can be mounted on a cabin roof or rail mounted using an appropriate threaded antenna base.
Customer review:
I am delighted with our new antenna. Our Navtex , normally somnolent in the marina, has burst into life!
Someone asked me recently – why bother with Navtex? My answer was simple. Last year a gale blew up suddenly on the Turkish Aegean coast. The Navtex transmitter at Izmir issued an urgent gale warning out of ‘normal hours’ and it was the only service to do so! For example there was nothing about this gale on PredictWind on our WiFi.
Now had a full month on the boat in Turkey cruising around and am even more delighted than ever with the new antenna!

RG 58 10 m Cable pack
Coaxial cables are vital to the performance of your antenna and radio system. Selecting the best coaxial cable has become more and more complicated as more suppliers are offering a broader range of products. The cable selected will affect the system’s cost, coverage and reliability. That’s why for our antennas we only use one type of coaxial cable, the TOP PERFORMANCE RG 58 CU MIL, designed to guarantee the best signal transmission.
