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.

      Have not fished down there but up river a little way in the Ramsey area I have been doing well on smallies Either trolling raps up river bouncing of the bottom or drifting down pounding the shorelines with meps spinners.   Meps are one of my favorite lures for the river that and buzz baits.   The Mississippi is fun because you have a chance at catching anything.

      Im wanting to go and fish the missisippi river by my place, there is a little inlet with some down trees, a drop off  and a little bridge that goes over the inlet. Its off of east river road at the end of 79th.  I believe its called riverview heights park. My questions is, has anyone gone fishing there? I see people there quite often and have chatted with them a little bit, but haven't gotten much out of them. It looks promising for some largemouth and catfish. if you have fished there what works good? and are they biting now? I will be there at about 5 am tomorrow morning.

      Nuts, I had to leave Fraser on Monday for some business and a trip, but I think your MO is the right one. However, there are a lot of small (10-12") fish on the reef tops as of Sunday. You might try deeper water just off the tops. I'm not a fan of bobber fishing (like to feel the bite) but it's been a consistent winning method. Dick

      Thanks for the info guys. We did end up going and launching at Beanies. Ten bucks to launch. Not too bad. There is a for sale by owner sign posted there but it's obviously private for now. As for the fishing, it was slow. Pulled the plug at noon and headed for the Mississippi. Did much better there.

      i wanted a yellow lab and got over ruled on the chocolate.  Great looking dog!  Does not look 115 pounds

          Thanks!  She is only 40 pounds at 9 months old.  Don't think she will get much bigger. I was hoping to talk with some people at the game farm next month to see if i can get a great price on a pre-buy program.    I have some pheasant feathers and she goes crazy when she see me grab them.  I need to find a field that the grass is not chest high to plant them or better yet get some game birds and tie the feet off and plant those.    If you drive by Round Lake and see a red Tundra stop in and say hello. I am there most nights when it gets this hot.
