Vintage EFGEECO The Optonic Bite Indicator X2 With Sounder Box

These are my optonics from when I was a lad. All working and in nice condition for the age. Theyve been in a box in the loft for years

Hi and low tone alarms.

9v sounder box battery connector has been replaced.

I alarm has two fin wheel for less sensitivity and other has four fin for more sensitivity.

Alarms have longer brass bolts and nuts to take wind defender ears

One of the two brass bolts is mission on the back of the sounder box that hols the speaker but doesn't affect the operation.

Please check photos before purchasing

Any questions please ask
