Vladimir 06660 Posted August 17, 2023 Share Posted August 17, 2023 Test F5 on the pit .... the soil is dry chernozem mixed with loam .... the goal is flat gold. Gold weight 0.4gr...... located in the plane - the detection depth is 10 cm plus .... on the edge - the detection depth is 5 cm. with a plus . Gold weight 1 gr. ..... located in the plane - the detection depth is 15 cm . ..... on the edge - the detection depth is 10 cm. The ground , if the target is a little deeper , drifts into the iron sector . 1 Link to comment Share on other sites More sharing options...
Vladimir 06660 Posted September 4, 2023 Share Posted September 4, 2023 Сегодня искал F5 во время дождя.... первые 20 минут всё было нормально....потом детектор начал терять чувствительность - оказалось, что вода попала в защиту катушки - пришлось снять защиту и все восстановилось - дальше искал без защиты катушки. После пары часов поиска передняя пленка с кнопками напиталась влагой и началась проблема с кнопкой включения пинпоинта - он включается хорошо, но после отпускания кнопки пинпоинт стабильно включенным - чтобы его выключить, нужно выключить аппарат и включить заново.....теперь думаю как все Исправьте на другом F5. Обнаружено 38 целей, из них две ценные монеты, остальное - мелкий мусор и монеты СССР. Проверил количество проходов F5 с помощью детектора CTX3030 - процент попаданий в пределы 30 процентов, но еще большее количество промахов было отстрелено патронами из малокалиберной винтовки калибром 5,6 мм... .достаточно маленький патрон и он при нормальных показателях в этом грунте - даже Крепление на территории 5 см - дуэт в железном секторе. Я решил попробовать настройку Fisher F5 для работы на этом грунте, не теряя при этом удовлетворительных целей... и вот что получилось: Чувствительность 99.....THRESH 8.... tones 4 ....а потом перейдем к изменению EMI (кнопки FREQ) в положение 2 (нижняя частота) - регулируем баланс грунта - потом переносим EMI на 3 положения (выше частоты) )....начинаем охоту за сокровищами ...с этой целью глубина обнаружения увеличилась до 20 см.

Sven1 Posted September 4, 2023 Share Posted September 4, 2023 Above long post by Vladimir translated with https://www.deepl.com/en/translator ----------------------------------------------------------------------------- Today I searched F5 during rain.... first 20 minutes everything was normal....then the detector started to lose sensitivity - it turned out that water got into the coil protection - I had to remove the protection and everything was restored - then I searched without coil protection. After a couple of hours of searching the front film with buttons was saturated with moisture and the problem with the pinpoint button - it turns on well, but after releasing the button pinpoint is stably on - to turn it off, you need to turn off the device and turn it on again..... now I think how to fix everything on another F5. Detected 38 targets, of which two valuable coins, the rest - small trash and coins of the USSR. Checked the number of passes F5 with the detector CTX3030 - the percentage of hits within the limits of 30 percent, but even more misses were shot with cartridges from a small-caliber rifle caliber 5.6 mm ... .small enough cartridge and it at normal rates in this ground - even Mounting in the territory of 5 cm - duo in the iron sector. I decided to try setting up the Fisher F5 to work on this ground without losing satisfactory targets..... and this is what came out: Sensitivity 99.....THRESH 8.... tones 4 .... and then move to change EMI (FREQ button) to position 2 (lower frequency) - adjust the ground balance - then move EMI to 3 positions (higher frequency) ).... start treasure hunting ...with this purpose the depth of detection increased to 20 cm.

Vladimir 06660 Posted October 25, 2023 Share Posted October 25, 2023 Made a new acoustic device for F5. The result was good side and rear sound suppression. The sound is directed towards the operator - even weak signals from the target are heard. I tore the dynamic head away from the body (installing it on metal stands), which weakened the low-frequency signal - which improved performance in areas littered with iron.

Mike_Hillis Posted February 24 Share Posted February 24 I enjoyed reading your posts on the F5, Vladimir. I liked the modifications too. I didn't like using larger coils on mine just due to it being too nose heavy and how it strained my arm. You fixed that pretty well it looks like.
