Marina 11204 First Impressions


Was going to get a floater until I saw this magnetic one! 82 PER THERMOMETER with battery included. If the digital display starts to get dim, it's time for a new battery. And is easily hidden behind a plant. So far, they're all doing their job in my four tanks and I am quite content. I tested this in a cup crammed full of ice and some water. Sure enough the digital thermometer was way off by 6 degrees!

Marina 11204 Final Thoughts

The hotter, the faster.

I've checked it against two other thermometers that are accurate. Love it, it's easy to read and keeps an accurate temp. A bit large for anything smaller than 5 gallons, but that's to be expected. A battery can last you up to six months, I'd say, but expect more like three. I have to admit I had two reasons for buying six. However, Lucy at Zacro read this review and emailed me. A battery can last you up to six months, I'd say, but expect more like three.
