Maybe it's in my Scottish blood, mum was a Kilmarnock girl, dad from a small village near Perth and they met in London! As for yours truly, I was born in Iraq (father was by then the resident civil engineer supervising the building of a rail bridge over the river Tigris near Baghdad). With my Scottish/Arab 'ancestry’ I do like value for money, quality and with anything technical or electrical it must be easy to use. The Merlin Smart Gauge Battery Monitor now with a two year warranty can be fitted almost 'straight out of the box' so easy to fit and simple to operate!
One of our customers, who operates a 40 odd ft yacht for charter on the West Coast of Scotland, has the following to say about the Smart Gauge...
"Rob, I fitted the Merlin Smartgauge to my boat earlier this season after several charter clients experienced trouble keeping the service batteries charged.
After several week's use, I have to say that I find it to be an excellent piece of kit. Its main benefit is that it provides clients with what amounts to a "fuel gauge" of the service battery bank's remaining useful capacity. You can see at a glance when the battery bank is fully charged, and what capacity remains when it's not fully charged. Much more meaningful to the average sailor than looking at a voltage reading (although it does also give a voltage reading!). It's now easy to keep the batteries in good shape - when the Smartgauge shows only 50% capacity left, charge the batteries!"
It's also very easy to fit. Unlike shunt-based battery meters, the Smartgauge has just three wires - to be connected directly to the battery terminals, via small fuses. There's no disturbance to existing cabling. It really couldn't be easier. I gather that its other key benefit is that it is self-calibrating, so it still gives meaningful data as the battery bank ages over the years. We'll see how that goes. All in all, it's a great addition to the boat's instrumentation, and it looks neat and tidy mounted at the nav station".
- Battery state of charge (percentage) for main auxiliary battery bank.
- Battery voltage for 2 battery banks.
- Ultra low power consumption.
- User programmable alarms for low voltage, high voltage, low status etc.
- "Shuntless" design for super quick installation.
