Turbo User Guide

Read the light

Full power runs for 16 hours. That is your best chance of a quick recovery. It then drops to a level that is still stronger than an RT Standard, for 5 full days of tracking. The light uses less than 1 percent of the power.

Turn it on and off

Tap the case with the magnetic wand. The light color confirms the state. If you lose the magnet, take the battery out to turn it off.

Install the battery

The Turbo uses a 1/3N lithium photo battery. Marshall recommends the Duracell DL1/3N. Put the positive side toward the lid. The positive side is marked with a plus sign. Screw the lid on with your fingers. The round battery spring pushes back on the lid so it does not unscrew. The transmitter starts as soon as the battery is in.

How long the battery lasts

A new battery runs about 5 days. The first warning is a yellow light and a double beep, with about 3 days left. The second is a red light and a triple beep, with 1 day left. For the strongest signal, change the battery after 8 to 12 hours. If you fly more than 8 hours a day, use a new battery each hunting day.

Check it before you fly

1. Look over the case for wear.

2. Look at the antenna, especially the tip. Replace it as soon as you see a crack or bare wire.

3. Make sure the antenna protector is tight.

Replace the antenna

The Turbo antenna is 13.25 inches for 216 or 233 megahertz, and 7 inches for ultra high frequency. Use only a genuine Marshall antenna with Power Line Static Protection.

1. Unscrew the antenna protector.

2. Unscrew the old antenna with your fingers.

3. Screw the new antenna on hand tight. A small bead of quick-drying epoxy at the base is fine.

4. Put the protector back on.

What range to expect

Tested past 150 miles, line of sight. In hunting country the range changes with terrain. In the western deserts of the United States, hunts have run from 8 to 100 miles, depending on height, ground, obstacles, and radio noise. The Turbo has about twice the range of the Marshall RT, and about 4 times the range of an RT Plus.

How it mounts on the bird

Match the photo to the hardware you ordered. The bird photos show the leg and tail methods. They use a GPS transmitter so you can see where the hardware sits.

Point the receiver

1. The signal from the Turbo is strongest when the receiver antenna lines up with the transmitter antenna.

2. A bird on a perch holds its tail nearly straight up. Hold the receiver elements straight up.

3. A bird on the ground can leave the antenna nearly flat. Turn the elements flat and listen again.

4. If you can hear the signal both ways, use the flat position to pinpoint the bird.
