I sent an email to the vendor, but I don't expect a reply until Monday. The shipping weight for each unit is only 3.5 ounces, so I think the individual shipping cost on ten, or more units should be pretty reasonable. Then, of course, one would need to add the cost of shipping each unit to the individual buyers. However, the SpeedoDRD unit costs $70, and I'm sure the final, delivered cost of this item will be much less than that. I would guess the final, delivered cost of this unit would be $35, or less.

I'm in at 35 delivered.

Given enough of the right kind of sealant, anything can be waterproofed. Watch these Jeeps hit Sippy Hole and imagine what it takes to waterproof a Jeep ignition.

That makes the total at least six; I might get two.

I don't plan to make any money on this venture. As soon as I get a firm price from the vendor, I will post the delivered cost per unit to the United States. At that time I will accept payment via PayPal before I order the units.

After the units arrive, I will determine the domestic shipping cost via first class mail from the U.S. Postal Service. Then I will ship the units out individually as I receive payment via PayPal for the domestic shipping cost. I might add one dollar per unit to help cover my fuel expenses traveling back and forth to the post office. I don't want to lose money on this deal.

I'm in too ,Spud!

[SpudRider]

Good for you, Fish.

[SpudRider]

Of course, if the price isn't significantly more expensive making an individual order, I will let you know. I will only arrange a group buy if the cost per unit is significantly better than ordering the units individually.

I just completed a 12-mile ride across town for groceries. I mounted my Garmin GPS receiver, and recorded the odometer setting. Then I zeroed the trip odometer on the RX3 before departing.

I don't know the accuracy of a GPS odometer. However, here are the results.

Trip distance recorded by Garmin GPS receiver: 12.1 miles
Trip distance recorded by Zongshen RX3 odometer: 12.8 miles

My Garmin GPS receiver records hundredths of a mile, while the RX3 odometer only records tenths of a mile. Therefore, I don't know how close the stock odometer was to reaching 12.9 miles. However, using the most conservative estimate of 12.80 miles, I performed the following calculations.

12.8 miles minus 12.1 miles = 0.7 miles 'optimistic' on the odometer

(0.7 miles divided by 12.1 miles) x 100 = 6 percent 'optimistic'

Using the same, Garmin GPS receiver for comparison, the stock speedometer is running over 10 percent 'optimistic.'

[SpudRider]

As for myself, I would rather have speedometer accuracy over odometer accuracy. However, everyone must make his own decision regarding this matter. Of course, one could set the Jaycar Speedo Corrector somewhere in the middle, and he would have a 5 percent 'optimistic' speedometer, and a perfectly accurate odometer.

Of course, I am assuming my measurements are correct. I heartily encourage others to complete the same experiments, and report their results.

Maybe a sailor should pay more attention to detail; I didn't see where it said not to get it wet. While I appreciate the vote of confidence in my ability to waterproof this thing; now that I know it's a water-sensitive item, I think I'm going to have to retract my request to be put on the list for them. I can live with thinking I'm faster than I am if it's not fairly bulletproof out of the box.
Sorry Spud, and sorry for the double post; I haven't a clue how that happened.

[SpudRider]

No problem, Veteran. I understand your concern, and you are off the list.

Incidentally, I don't see a double post. However, if I do find it, I can delete it for you.

I am going to send another email to the vendor of the Jaycar Speedo Corrector, and ask him if the caveat regarding moisture is a CYA (cover your backside) 'warning,' or if the unit is truly susceptible to water damage.

Thanks for doing that spud! It would definitely be more desirable if there isn't a significant moisture concern

You're welcome.

I just sent another email to Jaycar. Here is the content of the email. I will post his reply as soon as I receive it.

Dear Sir,

I am attempting to put together a group purchase of your Jarcar Speedo Correctors from the United States. However, several people have expressed concerns regarding your statement in the User Manual which says, "never get any part of the module wet." Is this unit water resistant, or is it easily damaged by moisture? Can it be used reliably for motorcycle installations? Thank you.

[Huck369]

I'm in for the group buy.....

[SpudRider]

Thanks, Huck. We're half way there; I will probably get two.

[jimjr21]

I am in for 2 minimum. Have to talk to the other local owners. Maybe 4.
