The reviewer found it provides noticeably smoother level readings than typical swingarm senders thanks to its magnetic reed-switch design, and the 316 stainless steel construction is a clear advantage for corrosion resistance and long service life.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFiner Resolution:\u003c\/strong\u003e The 8' (200mm) short sender offers a 10mm resolution that gives more continuous and detailed level readings in shallow tanks compared with coarser 21mm units.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNon-linear Signal:\u003c\/strong\u003e The sender outputs 240-33 ohms (240 ohms empty, 33 ohms full), matching standard non-linear gauges for accurate indication.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRugged Construction:\u003c\/strong\u003e The body and mounting flange are made from 316 stainless steel to resist corrosion and extend service life in marine and RV use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNo Swingarm Slosh:\u003c\/strong\u003e Magnetic reed-switch design eliminates the float-on-arm mechanism, reducing slosh-induced fluctuations for steadier gauge needle movement.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete Kit:\u003c\/strong\u003e Includes NBR gasket, five SUS 316 mounting screws and quick wiring terminals plus clear illustrated instructions for a straightforward install.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReadable Gauge:\u003c\/strong\u003e The matching gauge uses stepper motor sweeping, an 8-color selectable backlight and a curved lens for improved daytime contrast and nighttime visibility.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThe 100TECH sender is ideal for boat owners, RV and truck campers who need a compact 8' sender for short tanks where higher sensitivity matters, or anyone replacing a failing swingarm unit who wants smoother readings in rough water.
