You’ll get a compact, corrosion-resistant 6061-T6 aluminum mount with Type III hard-anodized AMPS round bases, a 1.5" TPU C-size ball for vibration damping, and a 3.5" double-socket short arm that locks solidly for most small Garmin, Lowrance, Humminbird and Raymarine units (confirm AMPS pattern and weight). It’s CNC-precise, powder-coated on the arm, and durable in salt spray, though screws aren’t included and reach is limited; keep reading for full fitment and installation notes.
Some Key Takeaways
- CNC-machined 6061-T6 aluminum bases with Type III hard-anodize resist corrosion and maintain precise AMPS hole alignment.
- 1.5" C-size TPU ball and double-socket 3.5" arm offer 360° adjustability plus vibration damping for steadier electronics.
- AMPS-pattern round plates fit many Garmin, Lowrance, Humminbird, and Raymarine units, but confirm rear hole pattern and weight first.
- Powder-coated short arm adds impact resistance, though the coating can chip; anodize on bases won’t flake.
- Installation requires drilling AMPS holes and customer-supplied screws; recheck torque and fasteners after initial use.
How This 1.5 Ball Aluminum Mount Solves Common Marine Mounting Problems
Because you need gear that stays put in salt spray and chop, this 1.5" ball aluminum mount tackles common marine mounting problems with a few targeted design choices. You get 6061-T6 aluminum bases and arm that resist wear; the Type III hard-anodized and powder-coat finishes reduce surface degradation shown in corrosion testing. The AMPS-pattern bases provide positive engagement and simple installation on flat decks, while the 1.5" TPU ball and double-socket arm let you lock position quickly. Vibration damping from the TPU ball and secure clamping limits image shake and electronics fatigue, so you stay mobile and unfettered. Made for paddlers and small-boat users, it pairs well with marine GPS units and fishfinders commonly used by kayakers.
Fit and Compatibility: Which Garmin, Lowrance, Humminbird, and Raymarine Units It Works With
Which units will fit this 1.5" C-size ball aluminum mount? You can mount a wide range of fish finders and chartplotters using the AMPS-pattern round bases and 1.5" C-size ball arm. Garmin compatibility covers smaller Striker and echo series up through ECHOMAP Plus 42cv–45cv and ECHOMAP UHD2; larger Garmin units may need adapter plates. Lowrance models fit typical Elite and HOOK series that accept AMPS patterns or RAM-style ball adapters. Humminbird and Raymarine devices with AMPS or compatible adapter plates also work. You'll confirm fit by checking each unit’s rear mounting hole pattern and weight limits before purchase. For kayak use, consider the mount's weight and low-profile design to preserve stability on small boats.
Build Quality and Corrosion Resistance: 6061-T6 Aluminum, Anodize vs Powder Coat Explained
After confirming your device’s mounting pattern and weight, you’ll want to evaluate how the mount will hold up in saltwater and sun. You get 6061-T6 aluminum for strength-to-weight and fatigue resistance; CNC machining yields precise AMPS hole alignment. The round bases use Type III hard-anodize, offering Anodize benefits: thin, wear-resistant oxide layer, excellent corrosion protection without hiding tolerances. The short arm is powder-coated to add color and impact resistance; note Powder coat durability vs anodize differs—coatings can chip, anodize won’t flake. For freedom on the water, choose anodized contact surfaces and powder-coated components where aesthetics and extra protection matter. Silicone spray can help protect moving joints and reduce creaks on marine mounts for paddlers, especially when used on moving metal parts.
Installation and Adjustability: Using the 2.4" AMPS Round Plates and 3.5" Short Arm
When you mount the 2.4" AMPS round plates and the 3.5" short arm, start by confirming your device’s AMPS pattern and weight capacity so you can position the bases where they’ll support the load without interference. You’ll mark and drill per the universal AMPS holes, remembering screws aren’t included. Fit the double-socket arm to the 1.5" C-size ball, tighten progressively, and check torque limits guidance to avoid overstress. Use quick release mechanisms if you need rapid removal, but verify engagement before use. Adjust 360° rotation and socket clamping for sightline and vibration resistance; recheck fasteners after initial outings. Consider mounting near the cockpit for easier access and minimal obstruction to paddling deck-mount compasses.
Is It Worth Buying? Pros, Cons, and Who Should Choose This Mount
You've set the bases and adjusted the arm for proper sightline and vibration resistance, so now ask whether this mount gives you the durability, flexibility, and compatibility you need for the price. You get CNC 6061-T6 aluminum, Type III hard-anodized bases and a powder-coated arm that resist marine wear. Pros: solid build, AMPS fit, 360° adjustability, clear installation tips in guides. Cons: no screws included, limited reach with a 3.5" arm, check weight limits for heavy tablets. Customer reviews note toughness; alternative materials like stainless or plastic offer trade-offs. Choose it if you value rugged, compact freedom. Perfect Kayak Fish Finder Mounts offers a range of products designed for kayakers and beginners seeking reliable mounting solutions, including options that match this mount's specifications like AMPS pattern compatibility and durable construction, which can help you compare models and accessories; see mounting options.
Some Questions Answered
Can I Mount Multiple Devices Simultaneously on One Base?
No — you can’t reliably dual mount multiple devices on one base with this setup. The single 1.5" C-size ball and 3.5" short arm are designed for one device; attempting dual mounting risks poor stability. If you insist on dual mounting, you’ll need a purpose-built dual mount or separate bases to manage weight distribution and maintain secure positioning. That preserves freedom to reconfigure while protecting your gear.
Are the Round Plates Compatible With Non-Amps Hole Patterns?
No — the round plates use the AMPS hole pattern, so they won’t directly fit non‑AMPS patterns. You can, however, use alternate adapters or perform custom drilling to match different bolt layouts. If you value flexibility, you’ll want a properly sized adapter plate or to drill precisely and seal holes to maintain strength and corrosion resistance. Keep fasteners and alignment consistent to avoid stress on the arm and electronics.
What Screw Sizes and Lengths Are Required for Installation?
You’ll use M6 bolts; length dependant on your surface thickness and device base — typically 12–20mm for thin decks, 25–35mm for thicker mounts. Choose Hex socket stainless screws for corrosion resistance and secure seating. Pre-drilled AMPS-pattern holes accept standard spacing; countersink or add washers as needed. Verify thread engagement (minimum three full threads beyond nut or into blind hole) and use marine-grade lock washer or threadlocker for vibration-prone environments.
Is the 1.5 TPU Ball Sold Separately as a Spare Part?
No — the 1.5" TPU ball isn’t included as a separate spare in the package, so you’ll need to source a replacement if you want one. For replacement availability, check RAM-compatible suppliers, marine parts stores, or online retailers that list C-size 1.5" balls. Spare sourcing is straightforward: search “RAM C-size 1.5 inch ball” or contact the seller/manufacturer for official spares and exact compatibility before buying.
Does the Mount Interfere With Wireless Signals or GPS Reception?
No, the mount generally won't cause signal interference or gps blockage. You get aluminum bases and a short arm that sit beneath or behind devices, and the ball-and-socket design keeps antennas exposed. Still, metal near antennas can slightly attenuate signals in tight placements, so you should mount devices with antenna sections clear of direct contact. Test placement on your boat to confirm reliable reception before final installation.
