RAM® コンポジット ドリルダウンマウント (Garmin GPSMAP 73、78、78S、78SC対応)

I was a bit skeptical about the composite cradle holding up long-term, but it's been rock solid on my boat for three months now—no wobble or cracks. The universal AMPS hole pattern made it a breeze to bolt onto my existing dash plate.

The double socket arm and diamond adapter let me angle my GPS perfectly on the boat console. It held firm even through some rough chop on the lake this weekend.

The double socket arm locks down tight with zero wobble once I got the angles dialed in, and the AMPS base pattern matched my existing mount holes perfectly. Only gripe is the composite cradle feels a bit stiff when snapping the unit in place the first few times, but it holds the GPSMAP securely.
