Dakota Alert Kit (1) MAPS and (1) M538-BS

Pretty good with a few modifications
First of all I am overall pleased with the unit. It works with no false alarms. I am using it at about 500' and it works every time. I have had a few problems that other people might want to watch out for. This unit uses 6 AA batteries in a cheap little battery holder. After only a few months the internal connections on the battery holder started corroding and the unit would quit working unless I cleaned the connections almost daily. To solve this I made up a 9 Volt battery out of 6 C cells that were soldered together with wires between the cells. This connects to the little terminal block on the circuit board where the original battery connected. No problems at all after this. Plus the C cells will last 3 times as long as the AA cells, probably more than a year!
As one other reviewer noted, the auxiliary contact is only rated 5amps at 28 Volts DC. Be careful not to connect this to a large device. I used a small 12 volt relay and a battery to make the transition to a...
A great system
The manufacturer, Dakota Alerts, claims this system has a range of 2 miles, sometimes achieving 4 miles, depending on terrain. While I haven't tested its long-range capability, it works beautifully for me at about 600 feet through forest, and is easily picked up every time in the basement. The portable unit allows you to communicate with a person at the base station.

The only Driveway Alert that really works
Had mixed results at first, but very satisfied in the end (the MURS Alerts are the only Wireless Alerts that reliably work beyond 500ft !). I use them for both Wild Game detection and driveway notification.

My story ==> I bought 2 of the original "Reporter Alerts" about 5yrs ago, they worked fine for about 3yrs up to about 500ft. After 3yrs one of the PIR transmitters failed because of corroded batteries, so I bought 3 new reporter transmitters. By then Reporter had been sold to Chamberlain and the 3 new PIR Transmitters were ALL total junk (worked to about 50ft, if you were lucky... total trash...). So, I gave up on reporter/Chamberlain, although I still use the one old unit that just keeps on working.

Last year I purchased 2 Dakota WR3000 units with 2 extra PIR transmitters (4 total). Two transmitters worked to about 300ft and two worked to about 50-100ft. I used them for 1 year but have been very unsatisfied with the reliability of detection/transmission...
