Lowrance H2OC Power

10 posts in this topic

When the 2-AA batteries are dead or out of unit, my 12V DC cable will not power up the unit. When batteries are fresh and I plug in the DC cable, the unit says it is running on external power. Has anyone else had this problem?

Haven't tried it plugged in without batts, I'll try it and see what it does.

Sounds like something's wrong with your unit. I routinely use mine WITHOUT the batteries installed.

Is the LED lit up on your cigarette light adapter? If not, you may have a bad power cord or bad cig lighter. You can also try wiggling the plug in the cig adapter to be certain that it's making good contact. You should also check out the fuse in the adapter (just unscrew the end).

Hope this helps.

Yup. I had a bad cord too. Make sure the LED light comes on.

Yes, the light comes on when I have it plugged in. When I try to power it up, again with dead batteries or with the batteries out, the light goes off when I hit the power button and back on when I release the button. I'm guessing it must be the cord?

It's the cord. Had the exact same thing happen to me. Lowrance replaced the cord and it has worked great ever since.

Thanks! Did you by chance take to cord to the store where you purchased the unit or send directly to Lowrance?

I've got the ExpeditionC (basically the same as the H2OC). Problems recognizing external power started 2-3 months after purchase, no matter what the battery strength inside. Light always on at the plug, but the unit indicated that it was running off of the internal batteries. Called Lowrance. After an incredibly long wait on phone and asking me to try this and that, they agreed to send a new cable. I told them what I thought of the design of the cable connection (poor, at best). Same problems showed up with the new one after a few weeks, and I gave up for some time. I just got both cables out today after a month or so of ignoring the situation. Both worked fine. Frustrating, to say the least because you never can fully depend on it working when you might need it most. I'm not real anxious to follow Lowrance's next suggestion of mailing in the whole unit.

Such a great unit, it's hard to believe the poor cable connection design: the cable does not attach with a definite click or lock in any way other than that little plastic tab. The cable can't be attached at the same time as the wrist strap so took that off right away (not even sure where that is anymore...)

Other than this one frustration, I can't imagine a better handheld gps solution.

      6/17-24 at LaBelle's Birch Point lodge in NW Bay.   walleyes seemed scattered--trolled crankbaits and lindy-rigged leaches.  cool, wet, windy weather half the week.  no bass.

      Juan that is great area for smallies. The water looks clear for the rum it's time. It's a long way to the next landing so you might want put in in Princeton and fish to that access You can get out at highway 47 so that is not to bad. I forgot about that I was thinking you had get almost to Cambridge.

      Thanks for the update.  Keep this updated.  Heading up on Saturday for the week and need to dial in the bait for the week or if we are going to be spending all day looking for active fish.

      Been a decent year on Kab, but the variable weather has fishing in an unpredictable pattern too. Much like last year, saugers have made up a big chunk of the catch, but walleyes are coming around. LOTS of small 9"-11" 'eyes around mixed with some 15"-16" 'eyes and sauger. Some folks are still picking up some of the jumbo perch too. Little pike are everywhere and quite the nuisance.

      You kind of hit the weather bad this past weekend.  Wind, rain, and more wind not to mention cold fronts moving thru.  I was on the lake my cabin is on in the general area of Red and I had a tough time scrapping together a meal - and I've fished the lake for 15+ years.  Sometimes mother nature throws you a curve and no matter how good the lake is sometimes it doesn't matter.

      Looks like a Namakan fish.

      Hit the lake before 6:00 this morning. Fishing very slow again. Lots of mayflies on the water. Water 64 degrees. Got a bass at first stop but no more of those. ABout 5 walleyes and four pike in nine hours. Quit just in time to fight the 22 MPH wind (twice what was predicted) all the way home. Fish in 25 FOW. Most on Fin-S-Fish. numerous missed bites. Yesterday hardly missed a one. Not so today.   June 27, 2017 video link

      Froggin is a blast! I couldn't get any topwater action Saturday but just under the surface with a spinnerbait they were crushing it. Early morning it was suspending jerkbaits on weedlines. Not a single swirl on top.

      The walleye bite the past couple days has gone from Boom to  almost Bust! There have been a couple of huge May fly hatches the last couple of nights along with a large Rusty Crayfish molt that have been making catching walleyes a real challenge! We are still getting some fish but now have to earn every fish! Lindys with 1/2 crawler fished VERY slow in 18" to 30" depths has been my best presentation. Cliff

      Thanks guys!  We tried kayak fishing last year (around Labor Day I think) and the Rum was way too high.  We launched on CR 7 between Blue and Green lake and just ended up paddling the river.  Is that a good stretch for smallies?
