DIY Fish Finder Table. Step-by-step instructions.
I ran into trouble buying a fish finder table. Modern fish finders run on powerful and relatively bulky batteries.
All the tables I saw for sale had a niche for small batteries! Maybe I was looking in the wrong place, but I couldn't find a table with a niche for my battery.
I decided to make one myself.
I bought waterproof laminated plywood, made templates, and assembled the table. I planned this table as a temporary solution. Later, I wanted to make it out of HDPE (low-density polyethylene). It's a durable material, impact-resistant, and frost-resistant. But to process this material properly, you need a CNC milling machine. If we decide to launch small-scale production, I'll definitely write a CNC program.
The waterproof plywood table turned out great, but now I'm wondering if I'll make it out of HDPE. I sealed all the ends with high-quality sealant, and oiled the exposed parts with three coats of OSMO outdoor wax, drying between coats.
The previous table from an old fish finder lasted 20 years without any problems. This one will last even longer.
These tables are especially useful for small PVC boats like mine. Space is limited, and there's nothing to attach it to. Could I glue in some fasteners, like PVC zip ties? Of course, I could come up with something, but I decided to go this route.
Enjoy!
