GPS Speedometer

[Jefftowz]

anyone use one? How do they work? Is it worth the $?

 

[was thatguy]

I have an auto meter one in the Miller.
It’s cool. Has recall and all that.
I had to replace the receiver puck a few years ago with a new style with a battery or whatever in it.

Is it worth the money? If you want a speedometer I’d say yes it is.

 

[shunter2005]

I have a Faria gps speedo. Best thing about them is NO mounted antenna puck. It's enclosed in the speedo. Nice. The only thing I haven't gotten used to is it doesn't have instant results. It takes some time to catch up. If I'm cruising at 40mph or so and got to WOT it takes about 10 seconds to catch up with the boat. I'm told that it's somewhat common with most all of them, but that is just hearsay.

I have a Garmin 5208 mounted in my dash. requires a $200 "puck" to make it work properly, but the "wish-o-meter" bullshit is gone......

pitot tube speedo's belong in roll-bar, and jet bote's.........

For the older ones it was pretty common to have long lag times.. the new ones catch up pretty quick and in some cases instantly.

Dang, how old? Mine is only 18 mo.

Watch yore tongue mister!
My jet boat has a puck auto meter!
It’s instant up and down.
Recall shows 83 mph right now...

For the record there is zero lag time up or down. It picks up at 10 mph

I put together a teleflex/sierra 120mph GPS unit last year...came out to just around $200 all in IIRC. It works....about as well as the $50 R/C plane GPS speedo that's the size of a pack of gum that I bought a few years before, and velcro'd to the dash.

One thing I've realized is that speed measurements are not a regulated value...I've had 4 different GPS speedos and the one that came in my truck all running at the same time with about a 7mph variation at somewhere between 62 and 69mph. Might as well not have a speedo in the boat, unless you're looking for bragging rights, but even then...my GPS indicated 78mph could have very well handed you your ass in your GPS indicated 84mph boat...and vice versa. Pick one that reads on the high side....it makes your boat faster.

I'm in a good mood. Landed a much needed project today. Celebratory barley pops....

Starting work monday...

 

[Lunatic Fringe]

I put a GPS speedo in the Formula and it lasted 2 season's before the non-replaceable battery in the puck died.
I have a pitot tube speedo in the Placecraft O/B boat that has a perennially bent pick up tube so no reading.
The Southwind jet bote doesn't have a speedo at all.

I decided a few years ago I don't really need to know the number. I drive as fast as I or the boat care to go.

 

[Headless hula]

LMAO!!!
nah man. I'm already home. In wisco....

Lmao...

I'd better hang this shit up, before I ban myself again....

That’s what mine did a few years ago.
Supposedly the new one doesn’t die.
They said that the original ones were like a capacitor that needed current to stay alive, and the new one wouldn’t die. It’s been about 3 years with this new one and it still works.

I have no idea what you just said.

 

[Headless hula]

Nmea 2000 is a "canbus"...
Marine manufacturers something or other agreed a while ago that they'd all make products that spoke the same "language "....

You can have a "faruno" brand chartplotter, and a Garmin depth puck and a raymarine radar, and all the shit will communicate with each other using the same language.
Bunch of different brands, all using a universal, vs proprietary tech....


Nmea 2000 is the "universal language" for marine toys.....

 

[Chili Palmer]

I use the SpeedBox app on my phone. I had my son check it against the speedo in the boat and I'm a constant 5 mph slower than the speedo in the boat shows.

 

[boatnam2]

I have one, does seem to be slow the faster you go, took mine a minute to reach 103, going to check it against my GPS on phone next trip.

 

[02HoWaRd26]

Could the mount location of the antenna have anything to do with the bad readings?
I have the little rectangular antenna from Livorsi but haven’t used my new gauges yet, but i know the 4” puck on the roof of my buggy is claimed to be good to one meter, that being said I’d assume the speed on that one has to be correct but it’s also mounted in the dead center of the roof.

Nothing slows your boat down like a GPS speedo

Ain't that the truth? I remember how disappointed we all were when we first got a radar gun

We'e had some odd top speed numbers as well. But they work great for same day testing of changes like gears, props, tuning ect

 

[CobraDave]

Are the gps speedos and your phone pretty consistent with each other?

I checked top speeds once with recall against my phone and they were one MPH off.
Never checked it while under way, but its probably real close given that the top speeds were right there.

Mine has never shown any lag or delay of any kind. BUT, When I turn the key on I always let the gauge cycle through it’s start up dance, and then I start the engine. Takes about 5 seconds or so. I think it’s important to let it cycle for it to work correctly, but I can’t say for sure.

 

[lbhsbz]

A couple years back I picked up one of these for around $50

https://www.motionrc.com/products/s...MI07S09aGF2QIVisBkCh3xjwabEAkYAiABEgK90fD_BwE

Stuck it to the dash with velcro. It doesn't update as fast as the "real" GPS speedos....only every 1/2 second. But it worked well, is as accurate as any of them it seems. You can also plug it into a PC and it will map your travels. It also has an altimeter, which is of limited use on a boat. It was hard to see though with polarized glasses sometimes, and I'd usually forget it in the truck, so I bought a real one.

 

[farmo83]

i bought one only to figure out that Schiada and Rex marine used a gauge size no one makes anymore. I priced out changing it the size of speedo to a standard size and to re gel the hole and punch it back out was going to be quite expensive as there are multiple colors on the dash. I've thought about getting a reducing bezel but I don't think it would look right, as such I'm still rocking the pitot tube.

As far as radar guns and GPS slowing boats down, back when radar guns came out a family friend bought one to use on his 80 mph baja with a gale banks, brought that bad boy in at 64 mph. Next year he showed up with a 26 daytona with a 540 and a procharger. We joked that was the world's most expensive radar gun.

 

[ToMorrow44]

I have a Livorsi GPS speedo. Luckily I’ve never had to replace the antenna (it’s over 10 years old now). I also have a Garmin 741 and the speeds are right about the same. I use the Garmin while driving because I use the tenth of a mph for optimal cruise and trim.

[LGETT]

Have a Autometer GPS Speedometer w/ recall, it started reading slower and slower. I hear its the puck that needs to be replaced with a battery style.... Sh*t maybe my motor is just getting tired.......

Anyone else experience this and have a solution besides build a new motor..LMAO

 

[stokerwhore]

yes but they're heavy,lol. most boats go 10mph slower with a gps. all that extra weight dontcha know

Yep...I got the new style about 3 years ago or so.

The new Autometer Multi function is pretty cool, get more than just speed reading.

A couple of months ago, I finally took some time to rewire my Faria gps speedo to it's own circuit. Used the newly defunct chart light positive and ground wires. Last time out, I saw that it was working much better. Much better response and it now catches up pretty fast. It still takes a second or two to catch up when you throttle up, but it's now much faster than when it was piggybacked onto my tach power connection. I don't know why that would make a difference, unless it wasn't getting a full 12v, but it seems to have done so. It now matches numbers, very close to what my phone gps app shows.

 

[Justfishing]

Some things to think about. GPS uses multiple satilites, the more satilites the more accurate it will be. A builtin reciever may work but it is not the best. A remote puck would be best. The puck should be mounted in the open with a view of the sky and away from sources of interference.

The processor speed will affect it too. It needs 3 or more satillite signals. A puck losing and regaining satillites will slow response times. Things will process faster with a better signal.

Newer equipment should work better. Clean power supplies are critical to electronics.

I would trust a gps over other devices but it would be good to check the accuracy against another gps
