I have seen on the internet individuals who have a large screen speedometer on their surfski. What company makes those??

Hiking GPS perhaps?
Phones can do a good job too these days, if you can rely o. The waterproofing.

Phone apps are out there for other sports and probably cross over, but these units are designed for paddling. They are too spendy for me.

I get by with my garmin 310 and pass on the real time viewing of speed because I only downwind. I do like to overlay the data on my videos.

310's sample rate for speed is 1Mhz, which is ok for me, but the rowing unit below is 5Mhz, which should be considered if you want accuracy. They also have a wired impeller, super accurate.

If I did flat water, this thing would be on my list. Not really practical at my skill level (Oscars drills are humbling!) but I love the gizmos.

The Garmin Edge Units have a large screen that can be user-configured to display the data that is most important to you during your paddle.

I have mine set up with just Speed, Elapsed Time and Heart-Rate for races, but if you have an ANT+ enabled instrumented paddle such as one from "One Giant Leap" ( www.kayakpowermeter.com ) then for training you can also have it display cadence and power and record "power-over-time" for later analysis.

Details for the Garmins are here:

Yes, they're cycling computers, but they work very well on a ski/kayak as well...

Edit: Whoops, just noticed LPB's response above. Sorry if I duplicated info already provided...

Good topic Abel!

I'm also looking for something.
You may just be looking for a portable GPS?

I once had a "Speed mate" actually I still do.
BUT I always lost the little impeller so I gave up on it altogether.
It did the distance and speed and that's all I needed.

I see the new "speed coach" says it works without an impeller.
It also does paddle strokes...cool.
I wonder how they do boat speed without an impeller?


If that's the case I'll be interested.

Weeds and logs in my area you see that rip off the impellers.

The new "power meter" is WAY too much money for me.

There must be something else.

The NK Speedcoach has a wired pick up sensor; however the impeller is wireless... it mounts to the hull and sends a signal to the impeller. The only issue with the Speedcoach is it doesn't display km/h. It displays knots, m/sec or 500m pace. There is another unit called the Speedwatch which works on the same principle. It is very accurate and reliable, and displays km/h along with several other options. For flatwater, especially on tidal rivers, these are far superior to GPS. I've used the Speedwatch for several years now and it's been faultless. The only drawback with the Speedwatch is having to regularly replace the 9v battery in the transmitter, and although the user manual doesn't mention it, the battery should be removed after every session as the transmitter is very sensitive and will keep ticking over whenever it is near an electrical source, eg wires, fluorescent lights etc.

GPS only gives speed over ground, not speed through water. Paddle on a river and you might be moving the boat upstream at 4kmhr but paddling at 14kmhr.


I would use a Hall Effect sensor......

One of the highly accurate competition slalom water ski speed control systems averages passes in both directions hence can work out current if skiing on moving water. Devices for rowing or kayak could do same or drift on no wind day. Of course not as accurate as proper water speed sensor as current, tide, localised flow & eddies etc

Yep, it did the trick alright (I am formerly Chookman). It locked me out of the site totally and the only way I can get back on was to create a new account using a different computer! :unsure:

Speedmate was the best unit ever! Totally wireless and simple to use. Such a pity NK no longer make them.

If you still have yours, just buy a replacement impeller fron Nielssen Kellerman - they only cost around $30-40. The impellers used on the Speedcoach units are identical to those supplied with the old Speedmate.

So sorry Chris - new users have their first two posts moderated, again to stop spammers.

I thought I'd fixed your login after the spam checker zapped your original post, but I hadn't completed the task. It should be fixed now, please try again.

Apologies!

Maybe you're right Abel about the impeller.
I'll look into a place to get a few.

I'm really bad at knocking them off into the water though.

Too bad mine doesn't do stroke rate too.

These do cadence, work well with Garmin watches

Well I decided to keep my old faithfull "Speedmate"
I just ordered a couple of the fins with new impellers today from the US.

Just not in the budget right now for a fancy and almost $1000 system.

At least I will know my top speed, distance, etc.

Abel, let us know what you get when you decide.
