  Current Imaging Atmospheric Cherenkov Telescopes for Very High Energy
$\gamma$-ray astrophysics are pointing instruments with a Field of View up to a
few tens of sq deg. We propose to build an array of two non-steerable (drift)
telescopes. Each of the telescopes would have a camera with a FOV of
5$\times$60 sq deg oriented along the meridian. About half of the sky drifts
through this FOV in a year. We have performed a Montecarlo simulation to
estimate the performance of this instrument. We expect it to survey this half
of the sky with an integral flux sensitivity of $\sim$0.77\% of the steady flux
of the Crab Nebula in 5 years, an analysis energy threshold of $\sim$150 GeV
and an angular resolution of $\sim$0.1$^{\circ}$. For astronomical objects that
transit over the telescope for a specific night, we can achieve an integral
sensitivity of 12\% of the Crab Nebula flux in a night, making it a very
powerful tool to trigger further observations of variable sources using
steerable IACTs or instruments at other wavelengths.
