Is there much difference between the TST 507RV and the TST 510RV? They are pretty much the same price and the same options.
507 is a newer system. Besides the user replaceable batteries, you can program the monitor with a programming mode that reads the sensor wirelessly after you put it on the valve stem. The 510 requires manual input of a 4 or 5 digit code for each sensor.
The 507 monitor is much thinner and easier to mount, the rechargeable battery lasts longer and there were one or two other features which I do not recall.
I just ordered one for $59.00. Cheap price to pay for peace of mind.
Do none of the TST systems still come with the antenna extension?
Mine did, a "T" shape antenna with a 6' or so lead. That is all I have needed to stop the occasional dropped sensor.
