Rochie,

G'day Shane,

Just logged on, been away for the weekend. (Was it you who sent me a PM on the Patrol forum about this same subject?).

Anyway, so far I'm fairly pleased with the tyre monitor. I have a couple of issues that Derek is awaiting a response from HK for me.

The reservations I have at the moment are:

1) I have one of the first batch that he imported. The sender units have no ability to change the small battery inside them. I'm guessing this means they are a throw-away item after the battery goes flat in 3 to 5 years. The next batch have a removable cover for battery replacement.

2). I have found that one of the senders broke apart when I was re-placing it on the valve stem after adjusting the pressures. I was able to re-join it using a coating of Plastibond and it still works okay.

3). To avoid having the remove the senders, I believe it would be advisable to have another valve stem added to each wheel for the purpose of permanently mounting the sender. This stem could be placed in closer to the centre of the wheel, reducing the vulnarability of the sender from being damaged on the track. I have actually lost one of my senders, somewhere between Mt Ive Station and Iron Knob; so I've asked Derek to see if he can get me a replacement....preferrably one of the new style where the battery can be changed; if indeed it will work with my monitor system and the other original sender units.

4). I had an issue with another sender unit, which was telling me the tyre pressure had risen to as high as 46 psi. I stopped and checked it with my gauge and it was still at the 32psi I had it at all along. Just to be sure my gauge was okay, I checked a couple of other tyres too and the reading on the gauge agreed with the reading on the monitor for those other tyres. However, that seems to have been a intermittment problem for that sender as it hasn't happened again.

5). One of the senders on my camper trailer regularly flashes up on the monitor with "noS"....meaning the monitor is not receiving any signal from that sender. I leave it alone and it will eventually re-establish it's "link".....but a bit annoying/disconcerting.

Make of that what you will......I still like the concept of being able to program a sender for a particular "position" and then be able to re-locate that sender to whatever tyre I have on that corner of the vehicle....saves having to re-program every time you change wheel/s around. Also it means you only need as many sender as you have tyres actually "on the ground" at any one time......you don't need to have them inside your spare/s like the internal sender type set-ups require.

Cheers
