H2O speed reading

24 posts in this topic

Mine works fine above 1mph, but anything under, it just reads 0.00.

Is there a setting that I need to change or something. I know it can be done, because yesterday we had two side by side. One was reading .6mph and mine was reading 0.00.

Mine does the same thing. I have it next to a Humminbird GPS and it will read down to fractions of mph, but the H20 will still read 0. I don't know why.

Were they both in MPH or maybe KPH? I have a different brand and in KPH I get the tenths in MPH 1MPH is lowest no tenths.

Nope, both in MPH. The only difference was that Brian's is a non-color unit and mine is color.

As soon as we got over 1MPH both read the same thing (even in tenths.....16.5/16.5)

Are you running the latest software version?

No idea.

I just purchased it late last winter.

Errrr....neither will mine and I just got it. Lowrance shipped me this one last week after my other one had issues with the buttons.

Looks like it is an across the board problem with the newer versions.

Guess it's not me.

If anyone happens to find a fix, please let me know.

I have the Ifinder hunt, and if you go to digital you should be able to get what you want, I think

I should add that I had a ifinder pro and I liked it better than the hunt

I was messing around with this, thinking it was somewhere in the Trip Calculator's Threshold or Speed settings, but no luck.

Maybe you can try this:

On both of those units you've got there, hit Menu twice, then System Setup > Software Information... and check for different software version numbers.

My ExpeditionC is at Version 1.1.0, which is the latest, and I don't get any readings less than 1 mph either.

If all of the ones that can read .6 or whatever are ones with an earlier software version installed, and all of the ones with newer software upgrades can't do it, maybe Lowrance needs to hear about it so that they can (re)fix this in a future upgrade.

I was at the H2O FAQ:

"How can I get my GPS to read below 1 MPH?

One of the limitations to GPS is the fact that it cannot track movements very well that are below 1mph. For example, you could be drifting in a boat and move quite a distance over time, but the GPS position on your map may not have changed.

Fishermen who do a lot of slow trolling will often use a paddlewheel type speed sensor, to track their trolling speeds.

( Nore from admin,please read forum policy before posting again,thank-you.)

I have a Garmin Etrax and it will read right down to 0.1 mph.

I hope Lowrance does a software fix. As the recommended fix, a paddle wheel, does not work when the boat in in a side drift.

or going upstream on a river smile

That is a pretty poor excuse, it's obviously a software glitch. Especially when most other units will read that slow and even the earlier versions work fine.

The etrax is a older unit and at first would not read low speeds.

Garmin came up with a fix that was downloaded. One positive thing about Garmin is that they are always up dating their software.

I hope Lowrance gets on the stick soon.

I can see how it wouldn't be very accurate at slow speeds, but you'd think it'd give you a value, at least.

Did you check to see if there were differences in the software versions on those two? and perhaps it was the older version that could display the readings below 1 mph?

Lowrance fixed mount gps that use the gps puck show speeds below 1.0 mph. This is just my opinion, but I think the accuracy of the antennas and receivers in the handhelds is not as good as the pucks - and not as good of accuracy means not as good at calculating speeds. That's probably why they don't show it below 1.0 mph on the handhelds.

I know that even at normal trolling speeds of 1.5 to 3.5 mph or so, my H20 speed reading jumps all over the place compared to my 332s speed readings.

This begs a second question... was it a fixed mount system w/puck that showed the .6 mph reading and a handheld that read 0.00?

The strang thing is I run the year old H2O side by side with a seven year old garmin etrax. The garmin tracks down to 0.1 mph. Both use built in antennas. Go figure.

(IMHO) I believe it has something to do with software.

I have a external antenna for the H2O and when I get time I will check out the antenna thing.

Some GPSs seem to cut off at 1.0 mph. my old magellan did that. My 332 doesn't. I don't think my go2 does either. I always thought it was a software thing to keep the speed from jumping around while you are standing still.

I think you are correct. A gps doesn't automatically know the speed, it has to be programmed to calculate the speed, and programmed to display the speed. Not long ago there was a post where someone thought his earlier generation handheld was more accurate than the newer ones because the speed didn't jump around so much --- it wasn't more accurate, it was programmed to not update the speed calculation and display as frequently to prevent the jumping around ---- exactly what you mention in your post.

That's why adding an external antenna to a H2O won't make a difference --- the unit may have a more accurate reading of where it is and how fast it's moving, but if it's not programmed to calculate or display that, it won't matter.

    • We live in some sort of Bizarro world now - Sarah Palin calling Trump sinfully stupid.     Here's another one from Ann Coulter, who literally wrote a book "In Trump We Trust"    
    • You do realize that if the taxes were done that way, the cities would get $2.53 billion richer, and rural areas would get $2.53 billion poorer. The 7 county metro pays substantially more taxes (nearly 2/3 of the states total) than the other 80 counties in Minnesota combined, but only receives roughly half of the state expenditures.   Sorry to break it to you, but rural America is not fiscally solvent. Those citiots you speak of are bankrolling the entire country. It's easy to see on this chart: more urban states are to the left (givers) and more rural states are to the right (takers).  
    • I tried to purchase the screws yetti uses from Fastenal who is their vendor for the screws. They are only sold in large reels designed for a self loading screwgun. I finally called Casey at Glacial lake docks where I purchased my yetti and he sent me out the amount I needed. They work great to add additional fir strips. The plastic used to tie them together comes right off as you screw them in. Hope that helps. 
    • Sorry...was wrong on the specs.   Manufacturer is Core Ice.  It was 1450# for a 12' and 1250# for a 8'.  
    • I believe you want to use a zinc coated or galvanized steel according to the charts.  I'm sure someone will come along to correct me
    • In the back room there is a company that is using bonded foam panels (similar to garage door panels, but really clean looking), and had weights of 1250# for a 12' and 1450# for a 16'.  Aluminum trailer frames that could convert to a skid frame.  Can't recall the name.  I'm sure they were spendy, but I can see a concept like that going somewhere for the hardcore fishing crowd.   Yetti, Firebrand, Big Bite, and Glacier all had really nice display models.      Lots of campers (disguised as fish houses) out there at prices that make me want to jump into the business.  I was in two different manufacturers houses with prices well over $30k that had wire nuts for connections.  That is going to be a fun adventure for someone 2-3 years down the road when they find out their manufacturer saved $15 on their wiring.           
    • Thank you for all the help!  Ended up going with the Marcum VS485C.  After some research, there were a few other Marcums that were on the list (825 & 625), the Aqua Vu HD, and the Pan Cam.  The mini cams from all manufactures weren't what I was looking for, but they are cool and do have their place.     After seeing everything in person, I think the Aqua Vu HD had the best camera/screen.  The Marcums were a little bit behind, but the 825, 625, 485, and Pan Cam had similar real life clarity.  The 485 won out because of the $300 price point vs the others at $450-700, and was almost identical for resolution, other than the HD.
      I honestly think these cameras are all about 5+ years behind in technology in comparison to the broader camera/tv screen market.  Running off a 7-9ah battery is probably one of the limiting factors.  Another may be the cold.  The main reason (IMO) is that the manufacturers are hoping they can incrementally rape us by trickling out technology each year, similar to the computer manufacturers of the 90s/early 2000's.  For the price of a middle of the road underwater camera, I can buy a Chinese made 50" TV (these all have Chinese made 5-8" screens) and a GoPro or Sony Action Cam (which is 10x's the picture quality).
