Gem 2000 Radio Monitor - from HeliProz
Most radio monitors simply light a row of LED's to show how much voltage is available. The GEM 2000 also monitors voltage, but it goes much further than that. The Gem 2000 Electronic Guardian made by Electrotek also alerts you to other problems such as receiver problems, RX filter problems, stalled servos, bad switch harness and more.

 

 The Gem 2000 Standard has the LED on the unit.

The Gem 2000 Remote has the LED on a cable for remote mounting.

In use, the Gem 2000 is a no-brainer. Simply plug the connector into any unused receiver output (or use a y-harness if all ports are full) and turn on your radio. If you get a steady flashing go fly. If not, find the problem and fix it. (When battery is below a safe level the LED will just glow, not flash).

The Red LED unit has one of the brightest LED's we have seen. THE brightest LED we've ever seen is the one on the brand new Ultrabright GREEN models - this one will make you see spots if you look directly into it!

For those who want to just show off, we also stock the Gem 2000 dual LED unit, with two remote ultrabright green LEDs. (See pix below).

The GEM 2000 has been reviewd favorably by almost every major heli publication as well as used by thousands of top name heli and fixed wing pilots. Lightweight, compact and comes with unconditional lifetime guarantee from the Manufacturer.
