Mala GPR Easy Locator HDR

Post by topgpr »

Has anyone used this GPR before? It's center frequency is 450MHz. High dynamic range helps its penetration depth, but how is its penetration depth compared to a regular 250MHz antenna?

it's about same
hdr pro 450 mhz reaches about 600 cm in normal conditions, on same site 250 mhz shielded antenna might reach 800 cm.
obviously hdr data has much more resolution -thanks to direct sampling technology- than 250 mhz but you can not tweek the settings (stacking, number of sampes on a trace etc.)
mala uses some "hidden menus" which are sadly not user-accessable
i personally hate that.

No change of number of stacking? That sucks.
