Handheld GPS on 12 Volt Battery

Recommended Posts

Franchiz

This might be a simple question, but should I have any concerns connecting my handheld GPS to my fish finder battery? Just want to avoid using AA batteries; it seams each time I want to use the GPS, the batteries are dead.

AA batteries are only 1.5V each. Even in series they will output only the total of the number of batteries. Unless you are using 8 AA batteries in series for your GPS, you might want to reconsider or design a voltage-divider circuit to drop the voltage to a safe level.

What type of GPS? I'm thinking of getting an H2O, which comes with the 12v car adapter. If/when I do get this, I was thinking about buying a receptable and attaching leads to this so I could hook the receptacle to the battery and plug the GPS unit into it.

I guess I found the answer in the manual:

Your GPS unit operates from four AA batteries, or one DURACELL® NiMH rechargeable battery, or from 5 to 16 volts DC using the external power cable. If the power cable is used, the Expedition automatically switches to it if the external power is greater than the battery voltage. If for any reason the external power fails, the unit automatically switches to the batteries.

Thanks!

Gary, is that something you rigged up or bought? Looks like what I was planning on.

IMO, I'd kinda sorta go that way, but personally, I'd cut off those battery clips (or get a lighter adapter without) and crimp on some insulated female spade connectors.

      Caught 20-23 gills and 6 crappies. Fun day on the 10 inches of ice. The whole lake was close to the same where I cut all the holes out and around

      I’m still seeing very random thicknesses all over.  In the past few days I’ve been from St. Cloud to Winnie and have seen vehicles on the ice and open water on the same lake. I’m in Little Falls.  Tonight I checked 2 lakes NW of town.  Both had people fishing.  One looked to be safe for wheeler travel and the other, very near it, still had an open lead and you could see the difference between the first sheet of ice and the second. I hope it doesn’t get covered with snow anytime soon so we can still tell where the changes are. Be safe. Bring floatation and picks.  And don’t drive yet! Ruh ro....

      I was on a small north metro lake today and found between 2.5 and 4 inches. One of the spud bar holes I punched started spewing water up so definitely needs a little more time.

      I was out on Round Lake last night (12/9/17) for the first time of the year. I was very surprised to see 12 inches of ice. I checked a few other holes and found anywhere from 11-12 inches. Keep in mind, I was about 300 yds out from the southeast shoreline. I’m not sure if it’s consistent across the middle of the lake. I only saw one group with a snowmobile. All other groups walked out, at least where was.  Anyone have any reports for ice thickness on other lakes in the area?

      Alot of open water pockets on bigger lakes still, some people out on cannon on 3 inches about 60 yards or less from shore.

      Called baitshop, he said people are going out from beach and a couple houses out. Wouldn't say how much ice. Who's got an ice depth?

      Had great fishing out from McKinley in 28 FOW on Friday-Saturday.  Caught a great mix of dinks, eaters, and slot fish.  I ended up catching five 22-25" walleyes, but my guest on Saturday (Chris Larson) caught the largest at 25½".  Best action was using a chub on a plain hook, but small jigs and rattlers also had action.  Walleyes still didn't like the sucker minnows. I had 8½" of ice where I was (was 6½" the previous week).  But be very careful out there because there are bad spots as people have mentioned.

      Anybody walking out yet? Preferably would like to know Glenwood side..
