      Fishing Report Clubs - LIMITED MEMBERSHIP - Join Today - FREE   01/24/2018

      Fishing Minnesota had added a new menu item (see above) called Fishing Report Clubs. It's a way to keep the really good fishing reports coming and being shared only with those who also provide detailed fishing reports. We will only approve new members who request to join if they have already posted a recent fishing report in the area forum, associated with the Fishing Report Club area  you want to join. We are going to limit the number of regular memberships, in the Fishing Report Clubs, to the top 20  members in each Club, to those with the best frequency and quality fishing reports provided in the club and less so in the regular fishing report forum open to all members. The higher quality fishing report reserved for the club of course. If  you want fishing reports  around your area, I would Join Now, some of the clubs are starting to fill fast. Use the Fishing Reports Club link in the Menu above (after you've posted a fishing report in the regular area forum) and request to Join.

FishFinder Battery

Question

Markley

What is the best battery to use for a Humminbird 300 TX? Should you use a marine starting or Deep Cycle? Thanks!

Either battery will work fine for powering your Humminbird. The only problem you might run into, would be if the output from your motor's alternator goes higher than about 14.6v, it will cause the sonar to shut off. But that is not very common.

Either battery will work fine. The current draw form any sonar is low enough that you will get many trips before you will need to recharge your battery and you will probably never significantly discharge it.

The difference between starting and deep cycle batteries is that a "deep cycle" battery is designed internally to provide a steady medium current output and be able to be completely discharged and subsequently recharged. It's plates are designed with adequate spacing to handle this discharge/charge cycle without damage.

A starting battery is designed to provide short bursts of very high current and be kept under continuous charging by the engine's alternator. This prevents the deep discharge/recharge cycle from occurring. The starting battery has plates closely spaced to provide maximum current capability in a small space, but this design cannot withstand deep discharge cycles.

What eventually kills the battery is that every time it goes through the discharge/charge cycle, the plates slough off some material, eventually plugging up the space between themselves.

How do the "dual purpose" deep cycle/starting batteries stack up?? I have 3 of this kind, that I also run the trolling motor and graphs off of.So far, I have not been seeing any problems.

OK D-man, I'll bite. Now, I'm not trying to be a smart a$$ here. But, since it is obvious that many of us are running our locators off of our starting battery without problems, why are you so against it. I know it would be bad if you were to runn the battery completely dead, but as long as the charging system keeps up the battery, I don't see a problem.

Again, no offense meant here, I just want to know WHY before my boat explodes or something.

I've got a couple of the dual purpose batteries too. I've always wondered if its just a marketing gimmick. But I don't really know and like to find out.

I ran my LMS350 off my starting battery all year with no apparant battery problems. But the electronics do drain it down, leaving me vulnerable to starting problems. So, I am installing a deep cycle battery dedicated to running electronics. I'm a firm believer in deep cycle batteies now for those low current long draw applications like the depth finders.

Trial and error and personal experience. I dont understand why boat dealers wire accesories to a starting battery? I dont think there is any danger or concern for expolsion. If you have the room, its better to add a second deep cycle. You can certainly use accesories on a starting battery but the life of the battery will deteriorate and when you go start the motor someday and nothing happends,just make sure your pull cord is in good condition.Hydro's post explained it well.Also you need to remember that most mid-range motors put out 6-8 return charging amps.Bigger v-4's and v-6's put out over 10amps. But these return charging amps are at max running RPM's.

The exact problems I've had running the electronics off the starting battery is this: the electronics drain it down. If it's night, the running lights also come off the starting battery, as does the live well pump and bilge pump. If after fishing for an hour or so, the motor cranks over slow, the fishfinder turns itself off on low voltage, and I hope my 120 hp. Force actually does start. I bought a small starting battery for about $40 last year. Might have been wise to spend another $20 but since I also need a trolling motor back up battery, the obvious solution for me is to buy a deep cycle battery and take a load off the starting battery.

      Has your tip up been in deeper water, shallower or the same? I’m hoping to get some iced this last weekend of the season. Devils Lake in ND is a good bet.

      Catching a lot of them in 34 feet

      Back on the Horseshoe chain I put in another 7 hours seeing zero pike yesterday.  I must be using the wrong decoys since I can draw in sunfish, crappies, bass, and catfish all day.  Finally caught a pike on a tip-up outside the house so at least I didn't get skunked again.  Looks like that will do it for spearing season unless I can figure out a North Dakota lake to try...

      Quick report from last weekend: Fished a couple midlake reefs in big bay and the walleye seemed to be non existent aside from a few dinks, although, the action was pretty decent. Jumbo perch, tullibee, and a few crappie kept me busy. From hearing other people’s late season reports along with my experience last weekend it seems like a lot of the walleye have moved to different types of structure, perhaps shallower?? I’m not sure, but had very few marks that appeared to be walleye.

      Agree Pike they new there Stuff bought a few guns there and great prices!
    • IceHawk
      Anyone one of you guys ever use Dave Smith decoys?  They sure look realistic but wow come with a price. I like the avian X and I have a couple custom painted from a artist friend that look real good also.  Yes I  realize  a lot of people  don't use decoys. And I realize there is a time and situation for that  But I'm kind of a decoy junky lol! i rarely find my self going with out any. 
    • mrpike1973
      I agree Ice Hawk. I liked Sportsmans seemed to have more people that actually fished and knew what they were talking about for help.
    • IceHawk
      Great vid on my bucket list also. I always loved seeing those peacock fisherman throwing  those woodchoppers. Seems like a very aggressive fish I need to target someday 
    • IceHawk
      Bring a scoop of each and try a variety the fish will tell you what they are preferring. 
    • IceHawk
      Boy your lucky sure miss the one in St Cloud  they always seem to carry a great selection for everything. We are kind of limited with only Mills and Scheels . Dicks just doesn't have it for me.
