Mini OLED Meters for Marine, RV and More

Bought this a year ago for my sailboat. It was slightly tedious to install, but it has worked great ever sense. Good brightness and quick reading. No sign of aging after a year of use.

High quality mini volt meter display. Much better than the junk you get from other listings. Wish it wasn't so deep but it mounted fine for my use. Very easy to read under all light conditions. I love it!

My motorcycle doesn't have a voltmeter, despite having an otherwise comprehensive digital display. So, I added this one. It looks great, is visible during the day, and not too bright at night. I get loads of compliments on it whenever someone sees it, and Blue Sea Systems gear has never let me down- I've used their gauges, fuse boxes, circuit breakers etc in my UTV and ATV's as well... it's always great gear and stands up to the weather, since it's been designed for boats.

I had been looking for a 12 volt voltage meter that measured to two decimal places for my RV. This meter fit perfectly into the existing gauge opening and connected to my existing wire harness. It is a great upgrade for my battery monitoring system. I highly recommend it. Worked great right out of the box.

This OLED meter appears to be well made, but time will tell if it holds up to sunlight, saltwater, and vibration. The meter was mounted on my boat's center console to monitor the trolling motor battery voltage. The Blue Sea meter was checked against a Fluke 117 DVM and found to be within 0.01 volts of each other. Since I already had a hole in the center console that was too large for the Blue Sea, I had to make a custom holder. Otherwise, the meter easily mounts into a 1-1/8" dia. hole. The two electrical connections (ground and +V) are done with push-on, female spade connectors.My only complaint is that the meter is not readable in direct sunlight and needs to be shaded in order to be read.

Great volt meter. I had to send the first one back because somebody returned a cheap one in the old packaging. Super frustrating. But the real product was exceptional.

I chose this voltmeter due to "marine grade" qualities and IP66, installing it was fairly simple and seemed to work pretty well at the time. Over the course of 2+ years, it began to lose some pixels on the OLED display and then abruptly died out of no where. I checked the fuse, it was fine, checked my wiring, it was also fine. I hooked up the voltmeter to bench top power supply and nothing. I'm kinda bummed as this is a pretty pricey voltmeter for what it is.

Installed in my Toyota Tacoma to monitor battery voltage. Fit in slightly enlarged hole from 12v socket I removed, and connected with a small harness I made to the 12V sockets connector behind the dash with small inline fuse per instructions. Reads the same voltage as my Fluke multimeter, and is easy to read in light. Not too bright in cab at night (I bought yellow one) been in use for months without issue in both hot and cold temps. Looks almost OEM. Happy with it. Well worth the price over the no-name ones on e bay with cheap quality and overly bright backlight.
