Macro Racer 2 with big deep coil

[sky3]

Hi, could Racer 2 match one of these detectors especially Relic Striker(same price), with coil deepest possible on Racer 2. There is video where compare Relic Striker vs PULSE STAR II vs XP GMaxx vs Sovereign GT vs GPX 4500, interesting, could Racer 2 match one of them with deep coil?

I don't understand that language so I cant say what's even going on in that video.
Sorry

I am curious, could racer2 with 15 inches coil or bigger reach same deep like detech relic striker did, or others detectors in that video, maybe is somewhere video where racer2 plus 15 inches coil is comparing with one of these detectors?
